Re: Needing head gasket wisdom

Don’t forget to have cyl head rebuilt( by a good rebuilder/shop) and check it for cracks first

440 ic diesel

I have found a running wreck of a 440 ic but a diesel, the one I have is a gas, 1958 by serial #, is the engine clutch the same- gas or diesel? Trans- or is all diesels 5 spd? Are any of the drive line parts heavy- duty, because of the diesel- S. clutches or brakes and finals?

Re: New OS piston clearance

I guess that is one therory of why cyl walls are honed. I don’t have bad results, because I don’t hone. As I stated, I remove top ring ridge ( to get piston out ) and if walls are relatively ok, install new rings etc and go. No oil burning or blow by. ( I have rebuilt many, both gas and diesel, line...

Re: broken bolt 440 steering clutch collar

I don’t know of any other way to repair that broken bolt. That is why I always put grade 8 bolts, and use neverseize upon assembly, of any bolted together piece. Grade 5 twist off to easy. Good luck!
