2003 996 3.6 Engine Failure

I bought a 2003 996 911 Carrera with 27,000 miles The doctor who owned it only drove the car about 2 miles each day.

On her way to work one morning the engine started to make a metallic noise, lost power and died.

The failure was blamed on the IMS bearing but no metal was found is the sump and when we pulled the heads off we had found a lifter had failed and the IMS bearing looked fine.

We had the heads redone and put in a LN IMS bearing and assembled the engine.

We started to crank the engine and heard a internal noise and then the engine locked up again, except this time it was tighter then it was before.

We verified the cams timing was correct, which it was, so we decided to pull the heads back off and go through the top end again, yet found nothing wrong..

Tonight we plan to split the case and see what has failed.

I might want to send the short block to California depending on what we find.Does anyone know of a rebuild shop beside MM that would do short block rebuild if needed.

We split the case last night, found the #6 connection rod looking like a S, but not broken. Still need to check further as to what could of caused this failure.

We just discovered that one of the mufflers has oil in it from the engine.

I kind of remember that when we pulled the head off that the bad cylinder had a light coating of oil inside.

Now the question is, where did the oil coming from.
