I know its loose, but it could still work. Not what I would have done, but could work.

Ok heres the deal... got off the phone with TSP... the pistons are 3.908s, which apparently is supposed to be the exact bore as well... when measuring the pistons they are coming out to a 3.905 to the coating, so I take it they have the clearance in the piston? So I do have the 3.908 pistons only with everything Mahle was telling us they are supposed to measure to a 3.905.

Sooooo.... that being said, I got a 3.908 piston (by the P/N) that measures 3.905 (which is correct by Mahle's book) with a 3.910 bore, so I guess I am actually .002 over what Mahle recommends.... mother ******!

No doubt it will run, but like I said if your going to have to listen to the pistons, they might as well be 2618's.....
