Guys I need some help.
I have a customer Mark Caslin from Ireland. He has 97 Mondeo 2.5. I sent him new rings and gaskets for the 2.5. He says his compression is now 15:1 instead of 12:1.
I do have to tell you that he got a crank from a Nissan (don't what model) and had it machined.
Do you think the piston rings are the problem or the crank?
Or could it be osmething else?
