ROFLBOT posted:* Engine mounts practically guaranteed to be hosed if original Definitely get the engine out to do all those jobs. If you don't want to deal with the hydraulic lines, it's only 3 bolts to undo and then you can leave the pump behind in the engine bay.

Passengers' side door at least had the plastic still there but it had been messed with and wasnt put back properly, so although the trim externally looked in reasonable condition, this is what it looked like from behind... The fibreboard base had got so wet it had shrunk and no longer fitted the plastic trim. Also there were only 2 of the 6 christmas tree clips holding the whole lot onto the door 😒 Not really worth spending time fixing that, just need to go find a replacement door trim. I did however manage to fix the door lock which wasnt working, this is caused by the little plastic clips that hold the metal actuator rods breaking and the rod falls out and if youre really lucky, it jams against the glass the next time someone puts the window down - so now you have a door that wont shut/lock, *and* a window that wont go up! The door handle/lock mechanism can be a real bitch to get at as the bolts that fix it to the door are obscured by the window guides. Once i got them out i replaced them with bolts with Philips heads in them because theres just enough room to get a screwdriver onto them which makes removal the next time that much easier.

So i got notified the OEM PS reservoir hose i had on backorder was actually no longer available, so i needed to find an alternative solution. Asking for 22mm trans/oil hose at any of the common retail automotive shops just gets you funny looks so i had to go to a specialist industry supplier to get some. Cost me $40 for enough to replace the few hoses in that size i could see. The OEM hose was L -shaped which is not ideal when trying to replace with a straight length, i'll need to keep an eye on it to make sure it doesnt kink and if necessary get one of those shape-forming coils. Whilst i had the intake out i thought i would start taking out the plugs and get the leads ready to come off for when the new parts arrive. For some reason there were signs of water in every plug hole, the plugs were a bit rusty and so were really tough to undo - like "im going to snap a plug off in the head" tough... Nice.... Not sure how you would get water in there, the plug tubes are pretty well protected Anyway i wanted to diagnose why it wouldnt start the last time so stuck a set of near-new NGKs in, put the intake back on and tried again. It wouldnt fire at all so figured the likely culprit was fuel, maybe the temporary pump i had put in had died. Bypassed the fuel pump ECU via a bridge in the engine bay diagnostics port (gives 12v direct to the pump). It fired right away and sat there idling as if nothing had happened, so another common-ish fault had occurred - the FP ECU had died. Will need to pinch the one off the parts car. Job list is supposed to be getting shorter not longer! ROFLBOT fucked around with this message at 10:18 on May 22, 2022 |

I was back at it again fixing various bits and pieces. Both door trims are now back on, the power mirrors and windows tested and working so all good there. I went to start it for some reason and had the 12v jumper in to the fuel pump as from the previous attempt i thought the FP ECU was dead, however even with a direct 12v it wouldnt start. I kinda had a hunch that the pump itself was the culprit again, so pulled it out... This has only been in since i got the car... it is of course completely dead now. In hindsight i should have prioritised pulling the tank before now but hey whatever, it has to be done because i dont want to stick another good pump in there. While i was in the back seat area i thought i'd pull out all the hifi/nav/tv modules that live there. They come out fairly easily and i figured it was worth getting them out to have a look at them because of the water that was in this area when i got the car, courtesy of a leaking sunroof umm.... Only this one had obvious water damage, the other 3 modules looked ok. Not awesome but not the end of the world as these are not essential by any means so i'll leave them out of the car until i can get hold of a replacement for the damaged one. In teh meantime i have to prepare myself for the fun times ahead replacing the fuel tank and filter....

heh well spotted, that’s my custom ancient Celeron CPU fan mod, theory being one of the reasons these things die so often is because they run hot in a small space with no moving air. With the pump itself being 100% dead it’s possible the existing ECU is actually ok, if so i might see if i can stick a fan on it too just to help prolong it’s lifespan

So this sat for a while as i was in Europe for a bit, when i got back a package was waiting for me Belts (including timing belt), dizzy rotors, fuel filter, complete spark plug lead set and some other bits. Not everything i'll need but its a start. So fuel tank time. First stop, the filter. These can be tough to undo but this came off pretty easily. At least its been changed before! The tank itself i was expecting to be a real PITA to get out, and it was. Theres 3 connections on the bottom of the tank that you have to get at with the diff/rear subframe in the way, in addition the rear suspension struts protrude into the cabin too much so they have to be dropped to make room. Struts lowered, filler neck assembly required a bit of finessing to get out of the way Still couldnt get the tank out because the subwoofer on the parcel shelf was in the way so that had to go Eventually it came out! mmm mud.... The replacement tank is clean and ready to go, just need to clean the fuel gauge sender and fit. Of course its not just a float/resister type like LESSER POVERTY-SPEC cars, its some magical electrical sensor thing. All i know about it is it doesnt like fuels with lots of ethanol in, it starts to give off whacky readings ROFLBOT fucked around with this message at 07:48 on Aug 7, 2022 |

This is what the old sensor looked like Everything in the old tank looked like this. Got the replacement tank all ready to go and tackled the usual fuckery of getting it back in place. Again this would be a piece of piss on a regular Soarer because there arent suspension hardlines and struts in the way. Crawled underneath and bolted the unions up, then started to fill with fresh petrol. This was the first of two noob errors as petrol started pissing out of the unions and down either side of the diff (a lot more than this pic shows) Wasnt keen to get under there and try to re-tighten while getting covered with petrol so slid a bucket under there and waited for it to all drain out To cut a long story short, after dicking about trying to get the unions to not leak, i realised there was a bigger issue and i needed to take the tank out again - gently caress! an hour or so later...

# ? Aug 27, 2022 12:21 |

Turns out there were metal sealing washers that had to go top and bottom of the union bolts but because half of them were already rusted on in place on the tank which i didnt notice, i ended up doubling up on washers with the result that all the joins leaked like sieves. Lesson learned - always seal up the tank, add some petrol and check for leaks *before* you fit it into the car!!! The second noob error came after i finally got the tank back in again and everything tightened up and leak-tested. I left the fuel filter out, hooked up teh battery and let the pump run for a few seconds firstly so i knew it was working and secondly to get rid of any crap that might have been in the line between the pump and filter The problem with doing this was once petrol started coming out i created a syphon and even with the pump off petrol was now pissing out of the line. gently caress! Figured i could get the filter on without getting totally covered in petrol, of course that didnt happen and 5 minutes later sure i had the filter all tightened up but also had hands, arms and sleeves full of petrol I LOVE CARS

it is but i don’t get why people make such a big deal about the starter motor since 1) in nearly 20 years of owning multiple 1UZ-engined cars i’ve never once had any issues with a starter, and 2) it’s really not much harder to take the intake off and have it right there on top of the engine than it is to spaghetti your arms around exhaust manifolds in a tight engine bay It’s really not a big deal.

well, when you compare it to like a normal 350 or something, where its just bolted to the side of the block almost dangling in the breeze, anything more complicated seems like an adventure. well, unless you have headers on that 350 lol plus it just seems bizarre to need to crack open the engine to change what should be an external accessory, even if it's something "easy" like an intake manifold. it would be like if they put the alternator in the bellhousing or the water pump inside the timing cover or something weird like that. sure you could, but you shouldn't.

I am blessed to be lean and compact, I found that day. There was basically just enough room for me to slip the spanner and twist it over the bolt head to get it loosened, and not much room to actually turn the wrench...later I bought ratcheting box-ends and those save my *life.*

I chucked a KMart seat cover over the ripped drivers seat which should do and just need to work on the seat belts so they retract better which is one of the things they always get people on. Then maybe one last tidy up underneath the car. There is a slight exhaust leak on the drivers side near the engine, will see what i can tighten up there but not going to put huge effort in if its something really difficult to get at considering its likely all going to come out at some point, will hope they don’t pick it...

I might have mentioned this already, but check that the sunroof drains haven't shortened themselves with time/age, in the trunk especially mine had popped out of the drain holes and had filled the trunk with water.

Slowly ticking stuff off the list. The persistent airbag light on the dash was a worry, this would be another licensing instafail. Thought it might have been something to do with my cap replacements on the central airbag ECU which would suck as to get at it again i would have to remove all the centre console touchscreen and hvac/hifi controls which is a bit of a pain. Instead decided to be smart and tackle troubleshooting as per the workshop manual. First step was to see if clearing any fault codes/resetting the system worked, of course there's no handy OBD tool to do this so what you have to do is connect wires to two pins on the diagnostics port and ground them to earth intermittently in a pattern. Of course this is fiddly and a bit hit or miss but even after trying multiple times it was obvious this was not going to clear the fault and turn off the airbag light. I struck gold on the next step though which was to check continuity on the airbag cable from the steering wheel through the column. After popping the airbag assembly out of the wheel i checked the cable and it was open circuit. Bingo! Of course i just happened to have a complete steering column spare so pulled it out and metered it the same way to check - it was fine. So it looked like the problem was in the spiral cable assembly (the thing with the yellow stickers above). Managed to get that off the column in the car without too much difficulty and opened it up... What the hell? How does that even happen? Anyway, that went in the bin and the spare one went in the car. Connected everything back up, connected the battery, turned the key and crossed the fingers Airbag light came on, and airbag light went off! Airbag did not deploy in my face. Success!

Someone didn’t remove the steering wheel before doing a steering rack and spun the shaft a tonne getting it back in, munching up the spiral cable? I’ve had to diagnose and replace three of them in Toyotas and Mitsubishi’s now- a 2013 hilux and prado and an 07 Pajero, all of them failed the same way where they wore through and went open circuit. Meanwhile my nearly half million km old 05 100’s spiral cable just keeps trucking along…

If you had to engineer 4WS on a car, how would you do it? Maybe hydraulically, with a couple of lines from the power steering pump to a rack just like the front? Maybe mechanically, with a steel cable to a pulley on the rack? Maybe electrically, with a motor to operate a rack? How about all three! The level of engineering just never ceases to amaze me.

loving hell Toyota! I've got a 2006 Nissan Fuga 450GT Sport aka Infinity M45S and it too has 4WS, or "Rear Active Steering". Earlier Nissan HICAS systems like on the 300ZX, GT-R and others consist of a 2 stage PS pump feeding a conventional hydraulic rear rack, controlled by the HICAS ECU. By 2006 the hydraulic rack is replaced with a fairly compact electric rear rack that connects to the rear lower link/spring mount - in non-RAS cars the inner end is simply solidly mounted to the subframe. Blue circle indicates where the rack end connects. I'm no super high performance driver, and I know people like to disable the earlier systems because they can leak and fail or "feel funny", but I like this implementation, I think it does add to the pretty good turn in this heavy lump has, and also pretty tight turning radius around town.

There's much myth and legend around it. The hydraulic versions - yeah they can leak and fail like a regular rack, and it's not worth fixing if they go. Otherwise, you remove it because race car or you wanna drift, which fair enough, or you remove it because guys on forums say you should. If it's working and none of those things apply, you just wanna drive it, leave it, it's fine. The modern electric versions are seemingly very reliable. I've driven the Honda Prelude version, and you really feel the arse end move around on those things, on my Fuga you simply don't notice it working, it just does its thing. Modern electronics go a long way. Just went on a dive: https://www.autoweek.com/car-life/a1871191/four-wheel-steering-demystified/ Honda’s first 4WS system, launched in April 1987 on the Prelude, was all mechanical, using a shaft to connect the front-steering rack to a slider operating the rear tie rods. Mazda’s 4WS, introduced on the Capella/626/MX-6 used a rear-steering shaft to transmit steering angle to a hydraulic actuator. Mitsubishi’s system debuted on the Galant VR-4 in late 1987. It worked electro-hydraulically on the rear suspension links, with no mechanical connection between the front and rear wheels. Toyota’s Dual-Mode 4WS, first introduced on the Japanese-market Celica in late 1989, was conceptually similar to Mazda’s, combining a steering shaft, rear hydraulics and computer controls. Nissan have been through a few different designs, with the very early (R31) system barely a step above the passive rear angle designs that relied on flex in various bushings in the suspension and subframes, to the hydraulic rack, then electric versions.

Raluek posted:are you sure that's japanese and not german? Definitely Japanese, because it literally never breaks. 5 UZZ32's in 11 years and never once had an issue with the 4WS system. And to be honest, I can barely believe it myself, the cars are now all around 30 years old. I've still got two, 4WS works flawlessly on both. Edit: Actually, there is a weakness. The power steering fluid tank's level sensor is mounted inside the cap, after repeated twisting of the wires when removaing the cap, combined with engine bay temperatures, eventually the insulation on the wires going into the cap can crack, leading to shorts or corrosion of the copper inside. Easily fixed with liquid electrical tape, though, but still a poor design choice.

Current developments - I finally got all the interior back in and cleaned up a bit, i didnt bother too much with the rear seats as these are probably not worth saving, the leather was so dry it didnt survive my manhandling it in and out of the car and the backrest in particular ripped apart which required a bit of gaffa tape repair in order to pass inspection Cleaned and silicon-sprayed the seat belts and sure enough that improved the retracting, enough so that they should be ok for inspection I had to make up another battery bracket as the battery im using is about half the size of the truck-sized ones these normally came with (and imo dont need) Was feeling good about ticking the final few jobs off the list and was mentally working out a timeline for booking the car in for rego inspection so thought i'd take it out for a quick test run, this pretty quickly brought me back down to earth and added more jobs onto the list 😠 The worst one was the Power Steering was doing some weird poo poo, felt like the steering was locking up occasionally. When i popped the bonnet after the run there was obviously a problem as PS fluid was leaking from the bottom of the reservoir - what i think is happening is the right-angled hose that i replaced is kinking intermittently and stopping PS fluid to the pump and/or its causing the leak. Time to take it all off and either fit a hose former coil or put a right-angled joiner piece in there, and hope the leak isnt from a crack in the reservoir... There is an imbalance coming from the rear of the car, feels like a badly defective tyre but i suspect this could be the dreaded bounce that is a telltale sign of the hydraulic suspension not working properly.... which shouldn't be the case as both rear suspension struts were refurbed and regassed so they should be like new? Ive printed out the workshop manual diagnosis sheet and will need to run through this to see if i can pinpoint the cause. The other faults were more annoying than serious, for some reason the windscreen washer pump that i had already replaced a few months ago had stopped working so that has to come out again, and one of the indicator bulbs in the dash isnt working either so the dash has to come out again 🤬 Maybe this year it might be on the road? 😏
