I needed to rebuild after 140,000 miles, so I put in .020 over JEG pistons. I know that the 7M is supposed to be a non-interference engine but the piston actually comes out of the block a little bit!!
There was .009 taken off the block and the head has been shaved twice .005 the first time and .006 the second. A total of .020(.5mm) I plan on using a 2mm head gasket.
Does anyone have a pic of the stock piston in the block? Does it actually crown out of the bore?
