Sucks for @Dryslick13 - hope you get out of it in the least painful way possible man.

Sent the IMS receipt to mechanic. He said he will contact LNE and at least try to get a refund for the bearing. Purchased in 2018. Will see what happens. Now have some things to worry about for my DD. 2015 Lincoln MKS EcoBoost. Changed plugs and found oil in inter cooler pipe. Installed a catch can to catch oil vapor hoping that the oil is just from the PCV system and not a turbo seal. If seal, will be upgrading turbines to billet. Power transfer case is also on list of things to work on. Going to drill a drain hole and tap for plug so lube can be changed. Seems like Ford also had some issues with mechanical design.

Honestly I think you know what I’d pick but for the sake of the OP and this thread… I won’t say it publicly. It’s a terrible situation.

Well this suck$ bad, so sorry.

This is way to common an occurrence at <100k miles (or on some engines much less miles) for a brand like Porsche, manufacturing this time bomb for over a decade knowing about this problem, along with all the other catastrophic engine problems this platform historically suffers from. Disappointing to see this type of German engineering, supposedly the best in the world...? Some say this is a direct result of the 'Porsche bean counters'. Well guess the bean counters were successful as this era in Porsche history proves to be very profitable and some would say successful... I'm an M E, so this is not my take on success...



Well, I'll give my failure analysis (2cents worth)...Tthe chain dragging, dragging sounds, marbles rattling in tin can, etc... all sounds from the last cry of imsb going south... When the imsb gets lose enough( or comes apart) it lets the chain bind maybe break or cause a guide to break up, maybe just jams the shaft . As soon as the chain binds up/breaks, shaft/chains stops spinning, and cams get out of sync with pistons, engine stops suddenly never to start again till 25-$75k is spent at a qualified Porsche indy shop, or an industrious owner does a diy rebuild for 15k or more. Or a 15k, LS or 2.7T engine swap

1) imsb comes apart or throws out *****/rollers etc, and gets loose enough to bind things up.
2) the shafts (cams,ims) then stop spinning with the crank probably doing an extra 1/2dozen revolutions till valves jam up on pistons with possible/probable catastrophic engine damage
3)This isn't like what came first, the egg or the chicken, nope. The imsb finnally 'hatched' and caused probable catastrophic engine damage imho...

B) any ball bearing that is pressfit in place can be damaged during install if not done correctly, the races can easily be pitted and the bearing will have a short life.

Don't know about this case but I've seen plenty of YouTube video of "mechanics" hammering bearings into place via the inner race

Dryslick13

IMS was installed by Ralph Lauren’s personal mechanic. He works on 918s, GT3 RS, Carrera GT, etc. Would hope he knew what he was doing, but who knows.

allcool

Ya, regretfully seen it too.
Wouldn't call anyone that beats in a bearing by its inner race a mechanic.

"Getting a full rebuild. Car will be better than new once finished."...This is simply not true. Most of the time rebuilds have issue that will require multiple trips to the mechanic afterwards, furthermore, other things can break during the rebuild process. Additionally, it's not only about the skills of the rebuilder but also the quality of the parts. Unfortunately, most rebuilds are disappointing. Lot's of threads online titled "engine problems after rebuild". Be realistic, not overly optimistic.

996-CAB

LN Engineering has a fact sheet on its site. Fact 9. To date, there are no confirmed failures of qualified installations of the dual row ceramic bearings used in the Single Row Pro IMS Retrofit, Classic Dual Row IMS Retrofit kits, or of the pressure oil fed plain bearing IMS Solution.

Did they mean to say there are no failures within the warranty time and mileage? Replacement for the first version was 4 years. 6 years and 75K miles for the newer.

For those of us riding on the Retrofit, please keep us up on this story.

Single row pro IMS retrofit kit was what was installed in mine. $799.

996-CAB

Single row pro IMS kit was purchased 3/18/21 for $899. Inflation. I would have gone with the Solution for another $1k, but I was looking at 20 hours of labor for a lot of other things and the extra $1K just wasn't there. Bought the '02 Carrera sight unseen from Porsche dealer, had it trailered from Chicago and had my indy build a needs list and execute. Cautionary tale for old car buyers. 20 year old car budget for a 996 is 25 hours of labor and more if you own a cab. But I love my car and it is a show winner, I track it, autox and drive daily in the season.

No that means they have not accepted a warranty claim. Even if you go the "certified installer" route there are so many gotchas in the warranty. Read it it's comicaly written, so they can make a claim like that. It's like the sign "best Chinese food" It's a fine product but don't kid yourself that it comes with a warranty.

Chris(MA)

Oh in that case I'm sure it was installed correctly
