EA71 headgasket question...


Recommended Posts

looking at a felpro fat-case gasket.. I recall ea81 gaskets also had some of the passages restricted/blocked.

 

My guess is that is has to do with restricting the flow so it circulates in the block & heads in a specific pattern to maximize heat absorption. the early ea71s did have problems with grenading pistons, perhaps this was a solution to these "hot spots"?

there's a certain board member here who grenaded the #4 on a 78 Brat. :(
