un stuck the b

[klg]

i posted the other day my new b was stuck, well after looking at it i went ahead and pulled the head and oil pan and one piston was hard stuck i got piston and liner out. my question is there is 2 hairline cracks between the liners the cracks go down into the water jackets there very small cracks but is this a problem to be concerned with looks to me looks like the head gasket will keep water where should stay but i dont know

Probably not a problem. As a matter of fact your lucky if you can find a block that does not have those cracks so yes the head gasket will seal them up just fine

glad to hear you got it unstuck, and I have one bare block w no cracks and one I just took out of a ca that was stuck, that block also wasn t cracked so that means I have two ....I must be lucky

If you find you need a sleeve because of that one that is rusted bad let me know I have a few of them laying around form engines I have built form junk engines

i cant make my mind up whether to try to fix that one or go ahead with new sleeves and liners on all of them. im going to have the head reworked because of the rust.

A lot depends on what you want or have to spend on it plus you do know if you rebuild the top and not the bottom you will be doing the bottom sooner then later. You might get by with new rings but you will not get by with less then that is you rebuild the head. BTDT and found parts wear about the same and if you do one area you better do it all or none or you pay for it in the long run. Sort of like the engine in my little truck. I did a cheap fix and replaced the head gasket and got 3000 or so miles out of it but right now I have the head sitting here in the house because it is cracked. Could have saved $100 if I had, had it checked instead of just doing it part way

I would put in a new sleeve kit. Have the crankshaft measured for wear at your local auto machine shop. They can probably get new bearings too. Hal

When I find small cracks on the top of the block or on the head, I "finger spread" JB WELD into the cracks.I don't know if it does any good other than helping me feel better.
