Im pulling my liners and pistons to try and resolve head gasket issues due to 0 liner protrusion,
First copper composit installed by previous owners shop went 22k until major blowout.
Replacement Moss copper composit only lasted 2k.I was hoping for another 20K
I then installed a racerorations Stainless and composit and ARP head bolt kit and it leaked after 1k
Liners are 86mm JRF with 25k,piston are 4 ring,two oil .155 one piece and two .062 comp.
Liner top to figure 8 flange is4.4483,protusion with 17-18thou (measured after removal)copper 8 gaskets was 0.
Thickest gaskets seem to be .021 from rimmer.
So it looks like Rimmers .021 copper would get me to .003 protusion which is still on the low end and I still need correct rings..
Option 2 is a new liner set if the flange to top is longer than my 4.4483.I dont know original dimension.
Any thoughts on currently available 86mm liner sets appreciated,or does it make sense to go 87mm.
Thanks
Tom
