Blown engine after Dealer Service
Mr. Raby,
The first paragraph in your reply to 20n78x8 above;
“A tremendous amount of M96 engines have seemed to fail just after Porsche service!! I have 1/2 dozen emails that have the exact same words that your post does and thats amazing!”
Made me think about how some dealers might service an oil change.
For instance
I have a Mercedes that gets free dealer oil changes every 10K miles. I change it at 5k intervals so every other change is free. My point is that the dealer has not pulled the drain plug on this car, the glyptol I put on the plug is never broken. They must suck the oil out through the dip-stick port. This leaves some “sludge” in the pan.
If a Porsche dealer were to do this with the “M” type engine couldn’t that also leave sludge in the pan? If that sludge were stirred up when the new oil is added it could migrate to the low mounted IMS bearing and cause failures. Are most of the above mentioned emails IMS failures?
