It is really going to depend on the person using it also. The best way is with a verticle honing machine, but not everyone has one in their garage or wants to pay to have it done.

damn one of those things i would have known if i would just think i little harder. but thatnks for the 8 valve reminder hybrid. and to answer your question. i bought the car not running so i planed on some problems like a blown motor. but before i had the money for a new one. but now can only afford good shape used pistons with rings. i will check it out in about a week when i get the car port space. it could be the rings but would it be so far off with just the rings? i mean 21-55-60-90 are not exacly close numbers at all. i guess i will find out when ripped apart. oh and how would i go about doing a leakdown check? thanks

It might not even be the rings man, the valves could be destroyed as well, a leakdown will definately help.

Most all race engines and most top engine builders hone by hand, not machine.

like i said. how would i go about doing the leak down testing?

if that valves are that bad, in every cylinder then its more then likely the pistons took a beating as well.

oh and using used rings isn't the best idea in the world, i mean it WILL work, but i wouldn't, used pistons is ok, but rings dont cost that much.

thanks i will look up the piston rings right now for a price. and i could use a head gasket off or a d16 z6 right?

[TheSilentChamber]

You need a new head gasket.

Are you sure your competent enough to be doing this?

[FrodoGT]

Yeah used rings or "iffy" it doesnt take long for them to wear in, and its not a good idea to move them, but if it must be done... Best idea after the leakdown, pull the head..that way you can inspect everything, and either way..you have a new head gasket on there afterwards.

LOL! He's probably more competent than you, Daniel look at your god damn ford. j/k

Anyways, yes use a z6 headgasket, and no it can't be a used one.

[TheSilentChamber]

Leave my ford alone.
