Yeah, it wasn't amazing for the price, but still worth it, I think. 15.5k. A bit squeaky, paint 7/10, a few other niggles.
Can't beat your 10k one for sure.
Local shop can do LN bearing for 1850, or oil squirter for 3250.

Lower-optioned GT4 goes for 90.5 on a 94.25 MSRP.
The seller showed me the car (since I'm local, I def wanted to see it), and it's not much different from brand new, so while it hasn't been used much, definitely impressive that it only lost 4k in a year and a half. That's going on the seller saying the dealer didn't mark it up; I dunno if he actually got a discount off MSRP.

Looks nice. When the GT4 came out I was a bit too early to get one, so I ended up with a 2015 CS. I love it, but there's a part of me that misses not caring about my daily driver. I think about going back to something invisible for a DD and buying an old 911for the weekend.

I know where you're coming from dude, but the sheer number of IMS retrokits with failed bearings is making me think the cure might be worse than the disease in a lot, if not most, cases. Only one I'd consider is The Solution.

Given the price point, I'm more inclined to gamble on fixing it. The Boxster was always a temporary car, so I felt much less guilty about riding that timebomb, especially for 40% of purchase price. Here, I think I'll do it in the spring. And the differential cost to do the squirting isn't that much.

I'm on the fence about doing the one on the C2. It's at 130k miles on the original dual row but the PO included an EPS kit which looks really solid so I'm torn between spending money fixing what isn't broken on a cheap car or looking like an idiot when the IMS goes while I have a retrofit sitting in a box next to the car. I think the current issue with the LN kits is that people think the original ceramic ones are a lifetime fix instead of an extended wear item which isn't helped by LN also having a true lifetime kit that's not always well differentiated. Also I think Raby has been huffing his own farts a bit much after the Solution kit came out like it's the only thing that would ever work.

I appreciate both Flat 6 and LN defending their solutions as their form of marketing. It's a pretty simple choice, imo -- risk it and run stock original, replacement bearing, or oil squirter. So makes sense that they would upsell whenever the topic comes up.

I have the ball bearings to do it but haven't gotten around to it yet. I'm also seriously mulling over the CMS shift arrester on the turbo, maybe on the C2 if I end up doing the IMS and clutch.

My rationale is this: I think it's pretty clear the OEM bearing isn't ideal, but it's also not clear the typical aftermarket solutions are really any better. Ceramics, cylindrical bearings, etc, aren't a panacea. Additional to that, removing and installing a new bearing is far from risk free. You can screw up mounting it (any number of ways), even cause damage to a new bearing before it's even installed. Keep in mind I'm saying this as a guy with over 25 years in the bearing industry so I might be a bit biased. I'm not even considering the non-bearing related things that can go sideways during the procedure.

In the grand scheme of 996/986 ownership, relatively few people would have actually gone through the effort of changing them as most people aren't ~enthusiasts~ but a browse of Rennlist and 6spd threads you'll see no shortage of threads where IMS bearings have failed and they were aftermarket solutions. How many were due to a lovely bearing and how many were just due to poor installation? Who knows. :shrug:

Since I have an early 99, personally, I won't be cracking mine open. If I had an OEM single row though, boy, that is a conundrum. I'm really not sure how I'd proceed.

Taking as gospel the 8% failure rate in the suit, and that it could fail without much warning at any point, I really want to do the oil squirter fix.
But I won't feel awful owning the car for a while without doing it.

Yeah, he's still the best but I soured on him when I actually ended up with the C2 which came with the EPS kit and from what I could find he dismissed it for dumb reasons. It has an optional oil feed part that has a really slick implementation but he got weird about how he would never do something like that and the Solution was the only correct way and that poo poo pisses me off because there's no way he could know since he had never seen it before. It gave me the impression he had just enough materials science knowledge to be dangerous and as one of the largest engine builders he went a safe and fairly obvious route but crowns himself as the gatekeeper of all M96 knowledge and technology.

Here's the EPS kit https://www.europeanpartssolution.com/ims-bearing-upgrade-kit/ and check out the oil feed modification. I was impressed by how simple and effective it should be.

It probably can't hurt, but it gets back to the failure mode of the OEM part.

Are they failing because of improper/inadequate lubrication? Are they failing due to fatigue? Or contamination? Poor factory install or part? Improper bearing selection in general for the radial/thrust loads in the application? Mixture of the the above? Rolling element bearings actually need surprisingly little lubricant for the load film (a properly selected sealed bearing can last for decades), but lubrication also assists with cooling and removing (and unfortunately also introducing) contaminants. The photos I've seen of failed bearings are so catastrophic I don't know if a person could realistically do a root cause analysis at that stage.. other than something blindingly obvious. I would be curious to know if someone actually found one at the earliest of stages and did an analysis.

The IMS fiasco due in large part to Porsches general denial and lack of a proper, endorsed fix other than replacing it with a like part is forcing people to do to shotgun approaches and I'm not sure which is the best way to go.

I believe the working theory is that the originals are grease packed sealed bearings but the engine oil gets past the seals and washes out the grease. If the engine isn't driven hard enough to get the oil viscosity down and regularly sloshing onto the bearing then it overheats and breaks down. It's backed by a ton of anecdotal evidence and theorycrafting but it's the current best guess and sometime I can definitely see showing up as an edge case.

slidebite

:colbert:

Yeah, I've heard that too. I'm not convinced of it either. If/when the seals start to fail enough to let oil past, any amount of oil that can get through to "wash out the grease" should be ample to lubricate the bearing. Reading threads about people talking about "rancid" or "acidic" grease and the like doesn't really make sense to me either.

That said, if I were to ever did one I'd probably be inclined to just remove the seal from the backside of the bearing altogether and let it be lubricated by the engine... which I guess is in essence what that oil feed kit does anyhow :v:

I am certainly late to this game and there is near 20 years old backyard/enthusiast knowledge into it (some of which are probably engineers and know far, far more than me) so I'm probably not going to help solve the mystery either.

So I took my 1986 n/a 944 in to get the brakes flushed and bled today by a local shop. I picked it up, and it's idling funny:

It was doing this briefly when I bought the car in April, but not once since then. I thought maybe it would clear up once the car was warmed up (normally it runs rough for the first thirty seconds) but it didn't clear up.

Vacuum leak? Idle control valve (which looks like its under the intake manifold)?

I fixed this this weekend. I believe it was the throttle position sensor. This link pointed me in that direction.

I still need to take it apart and clean it, but to fix it for now I just went WOT while driving and it apparently unstuck. Car drives fine now. Italian tuneup indeed.

Yeah in my '00 C2 you had to pull the door handle twice to get out of the car. The first pull unlocks the doors, the second will let you open the door. Obviously if they're not locked it's just one pull.

I can't remember if I've heard it autolock. I'm not even sure where the lock button is. Oh, the red light with the key symbol on the console? Why is it lit red? Should I read the manual at some point?

Drove it in the rain today, came around a tight but steady corner, heard Alec Guiness whisper to me "don't lift," didn't lift, but still felt the rear end step out a bit. Was ready for it to happen, so unwound just a little bit and got going straight, but the PSM kicked in and waggled around a bit.
For how slow and seemingly undramatic the corner was, the 911 doesn't mess around dynamically.
