Rebuilding Ford 4000 engine

[Jbrandon]

I am in the process of rebuilding the engine in my 1970 ford 4000 3cyl diesel. It had a broken crankshaft. I put everything new in but the rods and the piston height above block was .028 to .038. I figured the rods might be stretched because of the broke crankshaft so i installed new rods and now piston height is .022 to .028 above block. Is the height okay for a .056 head gasket?

I would have to look it up, but I believe that is right. The thicker gasket would be correct. The rods would not stretch though.

Thanks for the reply Tractor Tech. A mechanic mentioned that the rods could have stretched and i didn't know what else to try

I would probably stay away from that mechanic...

I would DEFINITELY stay away from that mechanic. His imagination may have stretched, but your rods haven't.

Haha, yeah, stay away from this "mechanic". But if you do see him again, ask him how the rods stretch. I think we all want to hear this.

I know he has rebuilt a lot of gas engines. He mentioned it after i told him the crankshaft was broken and it did lower each piston about .008 but i don't know if that is enough. Thanks for all the comments
