CARRERA4 2000 HEAD GASKET


Recommended Posts

I'm not aware that the cylinder head gaskets can be done with engine in car... it requires a lot of complex specialized tools and engine dis-assembly..

head gasket part numbers

996-104-270-06 cyl 1-3

996-104-269-01 cyl 4-6

Sorry, but perhaps you are thinking about the older air cooled cars.

The 996 has head gaskets and they could be changed with the engine in the car but it is likely easier to go ahead and remove the engine.

Based on my experience the head gaskets could probably be changed with the engine in the car, but what a PITA. I can drop my engine/trans is 3+ hours in the driveway, another 3+ to put it back in. I think it would save that much time from trying to do this work with the engine in the car. Access is really tight and a lot of stuff has to come off. Plus you have a lot of torquing and angle tightening to do with the head bolts, then setting the cam timing, etc. If you are going to do this you should also replace some cam chain pads, etc. etc.

What makes you think the head gaskets need to be replaced. The failure of the head gaskets is really uncommon in these engines.

I wouldn't even dream of trying this with the motor in the car. You can pull the motor so easily on these cars, just get it out, get it in the stand, and get to work. I would pull both heads, have them both pressure checked, at operating temperature, and have the heads rebuilt. You will new new head gaskets and new head bolts, among a bunch of odd seals. YOu will also need the timing tools to re-time the engine.

I've seen a few Boxsters and 996's with blown head gaskets, but it's VERY rare.
