Thread: 50 ford flathead engine

Not a normal flathead crack area. It's usually at the center two cylinders, across the valve seats and on each side as the exhaust is siamesed. Not an unusual occurrence for a flathead to have one or more cracks, sleeves installed and/or metal stitching at the valve seat area.

Your biggest problem now - to find someone locally that has a sleeve press and know how to use it AFTER you find someone that even knows what you are talking about

I can sleeve a cylinder myself as I've done it before, but was just wondering if a sleeve will do the job w/o welding the crack.

you need to know were the crack starts and stops at if in the chamber then it will need to be pluged . if it needs a sleeve that not a big deal if you have the machines to do the job. there must be someone that can do the job a round you? if you do not have a boring bar and plug kit .i can do the job and have welded blocks and used iron plugs. cold way is the best less you have a hole to fix then i welded them but this has alot to do with were the crack is some spots can not be drilled and plug so it gets welded

Thanks for all the replies. Guess I'll have it checked out to see if it can we welded as the crack is pretty long.
