block honing qeustion

[e30m20TurbO7]

so i just rebuilt my motor and honed it then i had to tear it apart 1000 miles down the road ,do you have to hone the block everytime you remove a piston , or can i get away with out having to hone it a second time

only if you change the rings.

Most of the time these blocks are so clean they don't even NEED honing.

A quite hit with a ball hone is the most you'd need but not likely if it were just done.

The cross-hatch honing isn't so much to clean up the cylinders as it is to get new rings to seat. If you don't hone the cylinders the rings will take a long time to seat, if they ever do.

As to the OP's question. Unless you are replacing the rings, they should be seated by now and there is no need to hone the cylinders.

Well, you're wrong.

if the block is under 200k you dont really need to hone. check the straightness and see if the top of the cylinder has a lip developing. and then judge for yourself. but i highly recommend replacing the rings and bearings while you are there. and dont reuse the rod bolts. ( i have reused but was worried the whole time i ran them) they are TTY.

i will be tearing down a block soon. talked to a machine shop guy today. he said a good hone and new rings will be fine. Even the slightest bore with OE rings will work. Not a good idea to re-use the rod or crank bearings?

thanks a bunch everyone , yea i never have used rod bolts over , i would have been so pissed off at my self if i reused them and then had a rod knock a second time, no point in cheaping out on 70$ in bolts. i dont plan on buying new rings though since i had already ran this block with these rings and they're already seated to the cylinders , and what would the lip look like on the cylinder walls if there was one , like a lip that your fingernail could run across or something more suttle

Don't waste your time and money rebuilding an engine without replacing bearings.

Do it right or don't do it at all.
