Case cast date?
I’ve searched around and while I found out the location and decode of the m96 head cast date marking I could not find anything about whether the case halves have cast dates in them and where that may be found. Does anyone know?
Background - the heads in my March 2003 C4S (door sticker) with first sold date of June 20, 2003 show a cast date of November 11, 2003 - so clearly they were not in the car when it was first sold. The engine number is from 2004 (M96/0366408445) and I’m trying to ascertain the history. When I bought the car some 8 years ago the previous owner told me that the engine was replaced by Porsche after it had repeated issues with the RMS.
The car was serviced by Sonnen Porsche - unfortunately they were bought out by Indigo and they tell me they have no records there of previous Sonnen Porsche work. Any help in my detective work would be appreciated.
