So i did a leakdown and compression test and came up with 2 bad rings and a slightly bent valve... i ordered OEM rings today and i am gonna start pulling off the head soon... im taking the head to the machine shop to get it pressure tested etc. Do i simply replace the rings or do i have to do something called a hone? dont know what that is but i read about it a few times..

It depends on how bad the cylinder walls are. If they have some deep gouges in them, then a hone won't suffice. You will need to bore out a little and get bigger pistons. However, if the walls don't look too bad, then a hone should do it.

If you are not too sure what counts as which then best to take it to a rebuilder for a pro opinion and any work done on it...

If you don't know what a hone is or when to use it, I wouldn't be trying to replace the rings myself. Find someone who has done this kind of work before and have them guide you or watch them do the work.

If you have two bad rings, you are most likely looking at a complete rebuild in the bottom end. Replacing rings and honing while the block is still inside the car, is what the automotive repair industry would call a half ass way to do it.

how many miles?

when you replace your rings, you want the cylinder walls to be true. if you just replace rings, your only fixing half the problem, since the bore may be worn as well.

My psychic diagnosis is a broken ring land. More than just a few rings.

You don't need to be honing FRM bores with any hand held type of hone.

Stop before further destroying the bores.

i see , so once the walls are exposed i can have a pro look at them and see if it will need any attention...if i have to pull out the motor to get better results then thats what i will do...i just didnt know what a hone actually was.
