What'd they do, run it on urine? The right side of that combustion chamber looks terrifyingly clean. What's the air filter look like?

Lifted the hood and found that they had chopped the air piping all the way back into an open fender (missing fender liner) and stuck on a K&N pod filter which had clogged up with dirt, collapsed and had an open airway directly to the MAF where the seam on the filter had torn. Closed the hood.

I'm in the same boat, I hate on their stuff pretty hard and people in the groups go no no no it's good!!! Yes because when the filter collapses in half and sucks in enough dirt to kill a turbo you have a great reliable product. I seem to think of someone had two similar toyotas with different filters and there was a long term filter test, but I could never find the article or post again.

Welp, my 90 Quattro designed to imitate a Land Rover and spill enough oil that the dipstick shows naught. Refilled, and now has a nasty lifter tick. Son of a bitch.

Those 5 cyls are notorious for having lifter tick if the oil pressure drops at all. I would even give it a second thought.

Sick of driving in the heat of Hotlanta, I finally broke down and devised a scheme to recharge the R12 AC system. By filling it with PC Duster, which contained Difluoroethane, AKA R152, which is an EPA approved replacement for R12 and alternative to R134A.   First snag: The Can Tap (green oil filter wrench looking thing) needs a pin to open the schrader valve so you can fill via the AC manifold, so I had to cut a small piece of metal rod and use it to push open the schrader valve on the tap. Then, filled like a charm. Success! After evacuating the system to zero, and then filling it with the R152, the compressor kicked on a couple times, then stayed on steady, the gauges showed good fill pressure, and the air is blowing cold. Then drove 150 miles to Guard Weekend, blew cold all the way, enough to start frosting the front window.

That doesn't surprise me at all. There used to be a video from some crazy Finns where they strapped a D24 to a dilapidated 740, stuck a stack out the hood (complete with flapper valve) and thrashed it in a field to the sound of Jessica Simpson's rendition of Take My Breath Away. I'm pretty sure at one point they put an Audi I5 diesel on there. https://www.youtube.com/watch?v=nZ-kZc0vlyg Here's more of that same car making the poof poofs. https://www.youtube.com/watch?v=rfNi6QXxva8 Later, it made more poof poofs. https://www.youtube.com/watch?v=uGpn3w0qigo It goes without saying that I would daily drive this fine automobile.

I'm going to be honest with you. Yes. It's water injection and not at all a clumsy hack to keep the engine working for long enough to survive an entire filming with that China Syndrome radiator leak.

Unless your compressor has its own oil supply, you're going to have to change it. R12 systems use mineral oil, which is not soluble in r152a, meaning it's likely accumulating someplace until your compressor goes dry.

Its PARTIALLY soluble in R152, its completely not soluble in R134, at least according to the tests I'm finding. http://docs.lib.purdue.edu/cgi/viewcontent.cgi?article=1443&context=iracc http://infohouse.p2ric.org/ref/22/21162.pdf So yeah, I probably need to change the oil out, but its not likely to be a major issue right now. Wrar posted:My parents had a Volvo 240 Diesel and it was a massive piece of poo poo. Apparently the design was modified from a 4cyl and it never oiled properly. It spent more time in the shop than out of it. From what I've been reading, the issue was exasperated by people not letting the engine warm up before use, and it demands synthetic only oil.

Considering that we lived in Miami at the time and we idled it out of the neighborhood being warm wasn't really an issue, and my dad was a huge believer in synthetic oil. It's just an awful engine.

It's just an awful engine. Warming up for a diesel doesn't just mean temperature, you have to sit and let the engine get the oil moving around. For instance: Detroit Diesels recommend a 5-10 minute warm up period before use in order to get everything lubricated before use or they will wear out prematurely.

I am glad to hear your conversion is working out well. I am planning on doing my Range Rover Classic AC with R152a, but my system doesn't have a low side cut off, just a TXV valve. I assume this will do all the poo poo that a low side cut off will, but I need to pick motronics brain a little more.

I found out why the 90 refused to idle properly with the AC on: The Throttle Valve Closed switch was pushed back and could not get contact, so the ECU was assuming that the engine was always at partial-full throttle, causing the Idle Air Solenoid to open late.

I think we chatted about it, and it got bypassed. I've got a bunch, and no VWs onto which to install them. I keep one set for the wife's Fit (wrong taper lugs instead of wheel bolts, yeah yeah yeah), but the rest can certainly go away.
