The aluminum piston will expand a lot more than the cylinder when the engine gets to operating temperatures. When that happens your clearance will be a lot less. 3 Share this post Link to post Share on other sites

Thanks👍 @953 nut Be sure you measure at the specified location. I too, think that it is a lot of clearance, but maybe measured at various locations you might find different readings.

Fordiesel69 214 #7 Posted March 16, 2018 Do not use the book to bore, the pistons today are NOT in spec at all. Bore with about 0.0045 for the style D Mahle and about 5ish on the heavy side for the regular style A. Share this post Link to post Share on other sites
