parrallel measurments of Cylinder to cylinder face's

Post by Gnasha » Sun Mar 01, 2020 12:59 am

I’m rebuilding a type 4 2.0 engine. I have ground all cylinders to a machined deck. The top of each cylinder has been ground into their respective head. When I place a straight edge across no’s 3&4 cylinders and I get a 0.002” feeler gauge under the straight edge at one end.
Is there a tolerance for this dimension?

Tell us how the cylinders are being held on right now. Spacers, washers, nuts?
What do you have for base shims, and what sort of sealant did you use between the cylinders and the case? What are the specific deck height numbers?
