Porsche 911

[02SE]

I don’t know about that, I see a lot of young guys in corvettes all the time . Most of the people I see in Porsches are getting up there in age of which I am one. In my defense I bought my first Porsche at 50 as a gift to myself when my daughter graduated “on time” And didn’t have to pay for an extra year or two of tuition!

It's all tongue-in-cheek. I'm just joking around.

If I were really concerned, I wouldn't have bought a very clean, low mile, last of the manual transmission C7 ZR1's. It was also originally ordered/owned by a guy I consulted for (now deceased) and has a plaque with his name on it from the factory. If I decide to sell it down the road, that provenance makes it more collectible. This car was bought to be a milder, more streetable sportscar, than our other sportscar which has become a bit excessive for the street.

As for Porsches, I've owned a couple. I always enjoyed them. My Brother In Law has a car fetish, and goes through vehicles faster than I do socks. He has had a string of Porsche 911's. Turbo S's in particular. He always offers them to me, but so far I haven't taken him up on the offers. Maybe someday I will. But I need another car like I need a hole in the head. I'm really trying to cut the number of vehicles that I need to maintain.

The '99 through '05 or so are replaceable while doing a clutch or similar, later ones aren't replaceable without splitting the engine case and the 'fix' there is to remove the bearing seal allowing splash lubrication by engine oil. This seems to work.

This LN link provides a lot of good information, but take it from the perspective that they are selling something, quality products, but still a sell: IMS Summary LN

If you are seriously considering one, talk to your local indy about the cars but also about any they know of for sale. There is a good shop near the Seacoast, but I don't have the info handy, and two excellent ones in Mass; EPE in Framingham and Sports Imports in North Falmouth. I have learned the best cars don't always get advertised publicly for sale and there is something to be said for finding a car via a knowledgeable shop familiar with the vehicle.

Actually, removing that seal was/is a preemptive fix for all of them. That bearing sits half submerged in oil in the sump, and removing that seal ensures its well lubricated. Lack of lubrication is often cited as a reason for its failure, and some outfits sell lube kits to "prevent" this. Totally unnecessary bc it sits in oil! For comparison, two stroke engines run upwards of 10k rpms and oil mist is the only lubrication for its ball bearings

I'm in the same situation; I replaced the Clubman, the TJ and the X1 with the Sahara 4xe. That does leave me with one extra garage space, so I may yet fill it with something different yet entertaining.

Problem is per his comments in this thread he sold his after only putting on like 25k miles. Some expert

If he can fix Mi8, he can fix 911.

Agree. Is someone now selling an oiler for the ball or roller bearings? I know the LN Solution is a pressure fed plain bearing, basically an add on to back date the motor, bit wasn't aware of any other pressure fed mods. The Solution seems successful, but I'm not one to mess with the oiling system and adding a spin-on seems a bit kludgey, and I know there were some problems due to filters.

I know LN says it is "sitting" in the sump, but is it actually? The shaft and sprockets are not really visible from the sump, it appears to be in a sort of V part of the engine case...almost looks like a dry sump case w/ rectangular drains inside of the wet sump. Now there is a lot of oil flying around and maybe when full, oil pools in the area around the bearing and sprockets or that is above the water line when full. Been a while since I was that deep in one.

Ain't that the truth

EPS, if I recall correctly, sells a modified oil pump shaft that fills the IMS with oil

I base my opinion on knowledgeable ppl, that I trust, on Porsche forums claiming it does sit in oil. I know of at least one source of an oiling kit for the IMS ball bearing. (It's been a while since I was researching all this and maybe not available anymore). More than enuff oil available just from it flying around during operation. In my opinion, the "problem" arises from overload, not lubrication (if oil is changed at reasonable interval). The 6204 appears to be too small to handle load while the larger 6205 and double row equipped cars have lower "failure" rates. Same oiling system, same oil, same load but better (larger) bearings that can handle the load, IMO

IIRC there have also been some engines that were machined with a misalignment that overloads the ball bearing.

The 996 is a wonderful car. The M96 unfortunately has more than one potential failure mode, especially in larger displacement form.
