What is the sound of one piston slapping?
What is the sound of one piston slapping?

I’ve posted variations of this in comments multiple times, so I’m just going to make a full post once so I can link to it in the future.

The secret to owning any M96 powered Porsche is to factor in an extra $3k. After purchasing the car, go to a reputable independent Porsche mechanic and have the following work done:

* LN Engineering IMS bearing retrofit

* Air/oil separator replaced

* Water pump replaced

* V-belt replaced

* Spark plugs replaced, coil packs tested

* Rear main seal inspected and, if original (doubtful at this point), replaced

* Misc. gaskets inspected and replaced on a need basis

* MAF sensor cleaned

* Fresh air filter, coolant flush

Depending on the miles and transmission type, consider replacing the clutch as well.


Do this all at once to greatly reduce labor costs, as dropping the engine once is considerably cheaper than dropping it multiple times should individual parts fail during ownership. Do this and not only should you have a car with a powertrain that only needs basic maintenance for the next 50k miles, but you’ll have the peace of mind in knowing that all of the common powertrain problems have been addressed.
