Motor # for IMS Research
I'm in the market for a Boxster, and the IMS debate is a issue, whether you prefer the cautious or the ostrich view. Currently looking at a nice '06, and the owner has provided me a picture of the motor number, from underneath. It looks like: M96/2662600784. I'm not finding anything that decodes like this. Trying to figure if small or large IMS bearing Any help? Thanks

Thank you....that being said, would YOU buy a car with smaller bearing and go the replacement/LN route, or a newer, larger bearing car, and just hope for the best?

Thanks, kind of the way I was leaning. Now, to find one.......

Nothing wrong with the larger IMS. Just be sure you have oil change history and the changes were every 5-8K mi or annually if < 5K mi / yr.

I was just pointing out that, in fact, a company made it possible to service them. And, I too, am concerned about metal shavings. But I'd be surprised if they don't have a way to address that possibility. Weakening the case? Well, I don't know that strength is critical at that point. Especially since the hole will be filled in with a flange. Yes, their flange. Because the hole would then be bigger and you need a bigger flange that fits it. And obviously no one else makes it. If they did, I guess you could use their flange too. :cheers: |

The company you mentioned also has a similar “fix” for leaking RMS which machines out the case crank opening to accept their proprietary crank seal. LN has an update “kit” for the cars with the oversized bearings as well, which converts the engine to a serviceable IMS configuration. The engine does have to be disassembled to do the install, but any future service can be done through the factory case opening. No case modifications are involved. At the end of the day, doing something just because you can is not always a good idea... |

Any boring has to be super precise to maintain the angle of the crank and/or camshaft to case angle or the pressure on the bearing is likely to be off center creating a ball on race (or whatever design) contact that it was not designed for. So in addition to shavings and bearing selection, you have to worry about precision of machining. Do you have the tools and experience to do it right?

:EDIT: So here's what I found in the comments when someone asked about the metal shavings: The reply from EPS: "...The key to preventing the shaving from falling inside the engine is the boring tool used. The shaving are pushed out as the mill tool is cutting by the air that is exiting through the cutting flutes. The engine is pressurized from the inside through the oil drain hole with approx 15 PSI. The pressurized engine will have a constant air flow exiting at the boring site prohibiting any shaving from entering the engine. Therefore, our EPS IMS Bearing can be the external solution without dissembling your engine..." I don't know if that's sufficient or not. Someone also pointed out that the bearing itself also acts as a dam to block the shavings from getting in. |

We should all thank God for JFP in PA. Goodness, I don't know how he has the patience for all of us!! He is, without question, the most knowledgeable person on this forum and also reminds us to use good common sense. Thanks Jeff.

Just so we're clear: I never said that one SHOULD do the IMS. In fact, I opted not to do my own, even though it's the model with the highest risk of failure.
I was simply pointing out that there is, in fact, a company that makes a tool to service the IMS bearings for the motors that people say cannot be serviced. I have nothing against Jeff. I know he has more Porsche knowledge in his pinky finger than I do in my whole body. I was just factually correcting some of his comments so people who read this don't get misinformation. He said those engines have the "non serviceable IMS bearing, period." But in fact, it is serviceable. A company makes a tool for that. If one wants to it's up to them, although I wouldn't. Another time he claimed that the IMS Solutions is the only permanent solution. I pointed out it only had a 5 year warranty, and there's another company that also claims to have the permanent solution, with the same warranty. If we're here to give people information, let's not limit them to just some of the information. Let's give them everything we can. |
Which bearing design used in those kits is more likely to do major internal to the engine damage if the bearing fails? And the warranty, is it good for the cost of the kit? I'd bet it doesn't cover labor or collateral damage.

No DIY. It has to be done by a "qualified installer" |
