LS was pimping ceramics for years with questionable benefits. Their plain bearing solution should be good though. e: But surprisingly seen a few failures of even those. I'm not planing on touching my OEM 2-row as long as I have the car. If I had a single row, I don't know what I'd do; probably look at changing it. Jake Raby said himself if he had an early year dual row car at this point he'd just leave it. slidebite fucked around with this message at 14:22 on Oct 6, 2016 |

Sell it to carmax and then buy it back with a 7 year warranty.

Originally posted this in the October thread by accident Happy turkey day fellow canooks. Had our get together yesterday, so today was catching up on weekend chores and I had a bit of time to work on the 911 a bit and continue on with the AOS job. Today's step was removing the rear boot joining the intake plenums. Because motors are assembled outside the car, the clamps holding the boot on were pointed up in the back of the boot, not on top of the boot facing forwards so someone working on it could actually get a hold of the head with tools. Compounded with incredibly tight quarters and a grand total of about .5" to work, it was an incredible pain in the rear end getting them out. Not even close to enough room for a 1/4" socket and universal. Luckily a buddy of mine has a flexible shaft driver so I borrowed it and wedged some spacers on top of the intakes to push up the sound deadening/insulation around the motor and the rear deck. With that flexible driver and and the 7mm socket right on the end of it, I wasn't able to seat the socket but luckily they were loose enough that I was able to just barely bite it enough times to loosen them. Elapsed time for 4 hose clamps? About 2 hours. I'll finish this job later, now I deserve a rye. Photo: Already loosened at this point, bolts were about 30 degrees rotated backwards facing up. e: Anyone have any ideas at "compressing" that center boot so I can pull it apart? It's quite stuff and I don't want to squeeze the middle too much because there is a vacuum operated flap there. I think that's the pivot point you can see in the middle of it. slidebite fucked around with this message at 14:20 on Oct 11, 2016 |

slidebite posted:I am certainly not convinced by a longshot that most of the IMS cures were any better than stock. Regarding that Boxster with the failed IMS bearing -- BaT took the auction offline, as LNE offered to repair it for the seller at a discount. A couple of points: - LNE makes various grade IMS Retrofit kits and an IMS Solution - the Retrofit kit requires an ok engine and IMS before installing. It shouldn't be used with an IMS that has already failed - the Classic Retrofit kit's bearing isn't lifetime, and is supposed to be serviced 4yr/50k mi. This kit was designed as a stopgap for dealers who wanted something in inventory for the IMS issue - the IMS Solution is permanent I wasn't aware of the distinction, and it seems like the seller got burned by that, too. His shop diagnosed a failed bearing and still put on a Retrofit kit. So even though the car was repaired in a way that LNE doesn't regard as proper, they're gonna help the seller out. Direct :sperg: quotes: LNE posted:Engine needs to be properly diagnosed and all of the details surrounding the failure including everything prior back to the original installation needs to be looked into. LNE posted:To answer your question about the cost differences between say, an IMS Single Row Pro Retrofit Kit and IMS Solution. The IMS Retrofit has a service interval where the IMS Solution is permanent. Nothing to fail and it’s proven itself pretty much impervious to wear. Case in point, we had a shop forget to install the oil line. Car left the shop without the oil leak and was brought back a hundred miles later because of the obvious oil leak. The plain bearing had no wear and was perfect. Proof that the IMS is indeed submerged in oil AND that a plain bearing should have been there in the first place, like in the Mezger engine. The IMS Solution is a much more complicated part to make, costly to develop and manufacture, and was in development and testing before any other IMS product. The other problem is manufacturing capacity. We cant get the volume any higher and get the price down more. We just can’t make them fast enough – it takes 4-5 months start to finish to make a batch. LNE posted:Everyone here asked for full disclosure. Here goes. My staff is well trained and do their jobs as instructed. We did receive a call from his Porsche dealership and there were notes taken and recorded in our system regarding this exact car and failure report: Hard to read, but lnengine's comments in the thread have got to be one of the most authoritative discourses on the issue: http://bringatrailer.com/listing/2002-porsche-boxster/ e: also, holy poo poo: FYI, we’ve verified that the cylinder bore material is very hard – high silicon and it contaminates the oil and will guaranteed damage the IMS bearing and even score an IMS Solution plain bearing. It’s analogous to the cash for clunkers liquid used to kill engines, just in small doses. kimbo305 fucked around with this message at 21:52 on Oct 12, 2016 |

It's pretty common to stuff pistons with high quantities of silicon these days so I'm not at all surprised a cylinder wall is the same.

I concur and it is good of LN to help out the owner. [Bearing guy hat ON] However, I am still very skeptical of the replacement bearing products on the market, especially ceramics. There are a few reasons for this. Ceramics serve 2 main purposes in the bearing world: 1) To prevent electrical conductivity through the bearing 2) To help eliminate rolling element skidding under low/variable loads That's really about it. Electrical fluting is not a problem on the Porsche and I don't think there is any evidence to suggest that low load skidding is what's causing the failures on the OEM bearing. If that were the case, the double rows should be more susceptible to failure and they're not. I guess it's possible you might be able to work something with a higher load capacity going ceramics but keep in mind only the rolling elements are ceramic. The races on the bearings are still carbon steel, typically the same as a standard bearing, and those have to be capable to work with the load just as the elements do. Even if you have elements which are capable of carrying massive loads, but that's not going to do you any good of the races they run on aren't up to the task. Furthermore, and this might be a bigger thing than most give credit to, even with "trained" technicians, you run a very real risk of damaging any bearing on install, especially a rolling element bearing in an awkward location. I literally cannot say how many times I've had people bring me a failed bearing that had only been running for a short while and I can either see evidence of terrible mounting OR when I ask them how they mounted them, they describe textbook examples of at least a few things of what not to do. Cylindrical bearings, depending on the design (I have no idea what the aftermarket ones are) can actually be more susceptible to being damaged due to incorrect mounting procedures than conrad ball bearings. I genuinely think based on the horror stories I've read about with failures on low mileage retrofitted cars, that it is entirely possible, if not likely, the OEM bearing would have been safer to run with than muck with it at all. I can say with confidence that I certainly would not open up an early model year car with a double row bearing under any circumstances short of direct evidence of the bearing being on its way out. If I had a single row bearing, I'd still probably not screw with it but wouldn't feel as comfortable as a double. That said, I am hopeful that the "IMS Solution" with the plain bearing should be a good fix if it's engineered properly and I am optimistic that it is.

It seems like LNE is at least aware that installation is critical, though they're still letting any shop out there do the work: "tech (which they fired) when they found he was using a zip gun to tighten the center nut of the bearing on the install tool used to drive in the bearing. He pretty much set those up for failure. We actually changed the installation tool so that you couldn’t put the nut on to prevent anyone else from making that mistake ever again." I'm guessing the tool amounts a cylinder or something to guide and press the bearing on?

kimbo305 posted:It seems like LNE is at least aware that installation is critical, though they're still letting any shop out there do the work: Gross generality for mounting cylindrical fit bearings Diagrams are for a single row ball bearing, but the theory is the same regardless of bearing style. Basic bearing install is to only put the mounting force through the interference fit race as per the red arrow. So, let's just say for an example you're putting a bearing in a block of a motor and the crank/cam/whatever is a slip fit. You would want to use even pressure around the outer race to drive the bearing in with a full circumference tool. So in this diagram, the red arrow is how you want to apply a nice even the force (outside race for a typical install) The inner ring is just along for the ride. Reverse if for an inner ring interference fit. Ghetto tool if you don't have a proper driver? A piece of pipe or even a socket that has the same OD as the race you are driving on. Don't have those? Clean the old bearing up and use it as a tool. Alternatively, if you have an application where you have an interference fit on both the inner/outer race, you need to evenly apply mounting force to both at the same time The absolute last thing you want to do is apply any mounting force exclusively through the race that doesn't have the fit and you are then forcing that mounting force through the rolling elements to the fitted race and will almost guarantee some brinelling and premature failure. This is absolutely a, if not THE major cause of failure due to improper mounting especially for ball bearings. Also, for the love of god, don't open the bearing until you are ready to use it and don't have it on your workbench next to where you are using your emery cloth to polish/clean up the shaft. I have literally seen brand new bearings on a work bench being showered with sparks from a retard with an angle grinder. Cleanliness of the work environment and your hands/tools is paramount.

God drat, trying to get the rear left intake manifold bolt out is absolutely kicking my rear end. It's literally the only thing holding me up getting at the AOS. I think I'm going to try and drop the motor a little bit to get me more clearance but holy poo poo, even if I get it out I'm a little concerned about getting it back in when I start buttoning everything back up.

Love the blue and it works with the tan leather. The previous owner sounds like a bit of a pretentious douche. I would be surprised if you can get a "free" set of tires on warranty. Tire warranties almost never work that way, especially on a sports car so you might want to do some deligence on that.

Are you kidding? He knows more about the car than even Porsche's top engineers. Tire wear from doing burnouts is totally covered under Michelin's warranty, that's why no one has ever bought another set of tires ever again in their life. Just go into any store of any type and they'll happily eat the $1400.

No, he was totally out there at 3 years old stealing newspapers and selling them. and of course he dropped out in grade 6 and everybody was cool with that. The deer he hit was named kevin and works at subway. He's leaving the country in a hurry and the cops totally aren't looking for the blue porsche that killed kevin. He seems like a rich kid still living on daddy's dime who was never told when he did something wrong, so doesn't believe it's possible.

Article with a $9K 250,000 mile 911 came up on Jalopnik and Jake Raby commenting that the early 99s were the cars to get. http://rennlist.com/forums/996-forum/958602-the-243-000-mile-99-just-popped-back-up.html#post13681487 Just furthers my confirmation bias that my 99 with relatively few nanny options is probably the closest modern water cooled to an "old" Porsche you'll ever get and I'll never crack that IMS open.

Tire warranties almost never work that way, especially on a sports car so you might want to do some deligence on that. I figure I'd get a rebate or some fractional discount to a new set on tire-wear warranties? I've never taken my tires back for that, anyway. Ether Frenzy posted:Just go into any store of any type and they'll happily eat the $1400. A tangentially related story that might belong in another thread: I did have a recent tire issue. I had a flat on a new tire and used fix-a-flat to hold it over until I could get it to a shop. I later noticed there was a nail through the crown, ok, should be an easy plug fix? As far as I know the tire never got lower than 20 (or even 25) psi, should be OK. I took it to Dobbs Tire, where I got the original tire, maybe two weeks after using Fix-A-Flat. The first tech who looks at it said it should be easy to plug, but I get a call a little while later saying they need to replace it because there was significant damage and that the tire was totally torn up. They didn't have any of the same tires available and that the only one that was in stock was ~$75 more, after warranty. I'm pretty surprised but agreed to a replacement under warranty. I later go in and ask to see it, the tech and then the manager pointed to the Fix-A-Flat residue as the tire damage. I told the manager that it was clearly Fix-A-Flat and not rubber. I scraped off the residue, offered him to feel it, and showed the tire below it. He deflected, said that Fix-A-Flat is a liquid and cannot be a solid, and said that the inner side wall was damaged. I asked him to show me and he had trouble finding the few creases, ~1 mm deep and a few cm long, from sitting at low pressure. I said that that sort of mark isn't structurally compromising, to which he said that the nail had not gone in the crown. It was pretty unbelievable listening to him come up with new things that we could clearly see weren't the case. I imagine tire shops get refunded if it's a warranty replacement? If so, this seems like a classic bait and switch bilking the manufacturer & customer. I imagine hardly anyone going through that shop asks to see their old tires. I contested it with the credit card because the tech who informed me of the damage on the phone was a loving moron and misinformed me. guidoanselmi fucked around with this message at 06:59 on Oct 18, 2016 |

There is a lot of anecdotal data that build years of <=99 have the best reliability for the motor at least for a 996. I bought a not quite dirt cheap 99 (still well priced) and while I admittedly haven't driven it a ton all my work is just maintenance. I have every intention of selling it next year as long as I get a reasonable offer. The car itself is rock solid, drives exceptionally well and everything works as it should..

So about two weeks ago the stars align and I finally manage to get the Cayman serviced and ask the shop to arrange the biannual safety inspection while they are at it. Car returns with a 985 EUR price tag for the service, but no safety inspection due to a number of defects. Fine, it has not seen a shop in three years or so, so get me a quote to get it fixed up. Quote arrives today after some prompting: 4,673.77 EUR, for sundry work on the brakes, suspension, and the a/c Thing is, I really only need it to be fixed up to sell it. It basically will not sell without the safety inspection, and it will not pass the inspection without some of the repairs Possible solution? I asked the shop if they weren't willing to pick it up. I'm sure they will lowball me, but it's not as if I'll get the full value of the repairs out of selling it either. Bollocks.

Can you do the brakes and maybe suspension yourself? The big brembos on my 911 cost a small fortune at the dealer but pads and rotors are reasonably available on the aftermarket and simple to do.

Motherfucker. Out. Finally. What a royal pain in the rear end, the final insult was after I had it exposed 2 of the hose clamps were those pinch-type and the eye to wedge open was in the most inaccessible position possible. The squeeze connect on the big bottom left hose refused to budge. Took me almost 2 hours just to free it. Then, as I was pulling the AOS out 1 of the hose clamps fell off and I don't know where. I have to find it - crankcase had an open port and if it fell in there I am having a bad day. The good news is I put my snake camera over it and don't see it in there - so that's a good sign - but I will not be able to sleep if I put this thing back together without finding it. Hopefully in the daylight tomorrow I will be able to snag it, then start on re-assembly.
