Hi All help pls ,
I use 76mm pistons 1000km after start problem
I removal engine I look gasket problem I added photo old gasket

This a new gasket size 72,5mm I use 76mm pistons I find answer this new gasket problem no problem

 

Your new gasket appears to be 75mm... you would need a 76.5mm opening if you are using 76mm pistons. You will likely need to buy a custom gasket since you are using such an odd sized piston, not something from your local auto parts store like you have pictured.

 

I look 2.5mm 76.5 head gasket
I don't want again problem for my turbo setup
My pistons 76 cp 1 year before replacement gasket now again
