The earlier two piece per bank V6 cam cover gaskets are GM part number 90511451, whilst the later one piece gasket per bank on later V6 models is GM part number 55351456.
Can anyone confirm either the engine no. or approx year of the change in the gasket? I am looking at doing the cam cover gaskets on my 2002 3.2, and wondered which type is likely to be fitted, or do all 2.6 / 3.2 engines have the later one piece gasket?
I would like to get the correct ones prior to starting the job (rather than hearing a suggestion to get the later one piece and cutting the two link sections between them should the car have the two piece fitted :-X).
TIA

2001 when they switched to coil on plugs...

The small extra bit of rubber that joins the 2 doesnt have any oil to stop so you could fit either without issues.
My 2003 has had the 2 separate seals fitted for the past 3 years without any issue.I suppose you could just run a bead of black sealant across the channel in the cover but my experience says it makes no difference.
