JDP does do used car reliability ratings. I don't have one from them on 5 year old or older. I think it's pretty much a given that a 5 year old or older car isn't going to be reliable, some exception to that yes.

JDP's 2015 used car reliability results. Porsche didn't make the cut in any category.

I think because this topic has been absolutely beaten to death. Hey - there is a rule about cats....can we get a rule about the IMS???

[Jamesp]

Cats will only take out Timco's engine. The IMS can take out anybodys' regardless of bearing choice. That's why it's worth beating to death.

Perhaps they don't need to respond.

The attacking party is wrong on at least two points which undercuts the credibility of his posts.

LNE retrofits come without outer seals (see attached photo from LNE website) and the expert claims they do.



Pictures shown in the two cited LNE failure examples show bearings with outer seals, which means they aren't LNE bearings to begin with or have been doctored

[Jamesp]

You cannot see the seal in this picture, its on the other side of the bearing. I don't think Porsche-land is lying. Any bearing can fail. The bearings shown do have the correct number of balls for the classic ceramic bearing and also have the correct number of seals which is one. What is not clear is what the operating environment of the bearing was. If there is contamination in the bearing it will fail, and as it does it generates more contamination. There is a reason the engines get screened.

Of course one cannot see the seal because its is on the inside of the inside and that's the point. Both the LN critic and his cited failure cases say / show respectively there's an outside seal. If so, they aren't talking about / showing LN bearings.

BTW: I fully agree with your comment that debris in the oil will kill a perfectly good IMSB once it contaminates the bearings / race(s)

It has already been confirmed that it is an LNE ceramic bearing, so this is not even worthy of discussion. I'm appalled by how quickly some of our members are to demonize anyone that doesn't worship Jake and/or LNE.
MB Motorsports has nothing but good reviews and personally, I feel that information regarding IMSB failures can only benefit the community.
Jake is also very valuable to the community.

Are we confusing the ball cage/shield for a seal? I think so
