19J piston clearances

TR3a · Jun 18, 2020

Can anyone tell me what the piston to bore clearance should be at the crown end. The manual states a skirt clearance but I want to see if I can reuse my existing pistons. A diameter measurement of a new standard piston would be useful.
Thx.

you need to do it at the skirt bottom,pistons arent perfectly cylindrical till they warm up

Yes, but I need to know what the top clearance should be.

I have always worked on 0.001" per inch of bore but I have never done a diesel engine before.
