HG seperation
 

Real quick, engine re-assembly commences tommorow(sat) I have a 3 layer z6 and want to take it down to 2. Whats the best procedure for removing the rivets without damage?

RE: HG seperation
 

Are you serious, no one knows how to do this, or has done it themselves?

RE: HG seperation
 

i wouldn't do it......Do it if you want, but consider the fact that the middle layer has staggered coolant orifices to help evenly cool the head and block.

RE: HG seperation
 

so which layer out of the 2 on a Y8 has this orfice?

RE: HG seperation
 

the middle one

RE: HG seperation
 

Y8 is 2 layer right? so there would be no middle. Either way fine, can i use the middle and one of the metal layers? How do i remove the rivets

RE: HG seperation
 

Why are you wanting to do this, the most you will be able to change compression is around .3 points and that is hardly worth altering you head gasket to acheive.

i just wanted to squeeze as much compression out as possible, but if its not worth it, screw it
