is there that much difference in them? any recommended rings? im gonna pull my motor to put in a new clutch and to put a new cam in. while i have it on the engine stand im debating popping out the pistons and re ringing them. and honing the cylinders. also in the event that i do decide to pull the pistons would i need to change the bearings or would i be ok using the ones that are in there assuming they are still in good shape in the same cylinder?

If the bearings and journals are still within spec of the owners manual and they aren't all gouged to crap from oil passage left overs then reuse them.

Rings are a different sort of animal, you might want to see how 'egged' the bores are if your engine has not been rebuilt yet.

Most likely a hone and ring job will be for standard rings, I normally use moly rings in my builds, but those are fresh bores and need a finer hone to finish after the overbore, not sure I'd recommend going that route on a hand rehone.

2 cents,

is there a way to check for the egging of the cylinder without the fancy tools?

Home hone job........cast iron rings.

My 360 munched up the #2 exhaust valve and spit it out the exhaust before I bought it. We hand honed the cylinders. Dropped in new pistons, iron rings. Over 150K on it. Never has burned oil. That cylinder was pitted. Head was destroyed.

You may be able to check with a new ring, and feeler gauges Just guessing!

Gday.
Do you own a set of vernier calipers?
If so you can get a set of "T" bore gauges for around $25.
they are a bit fiddly to use but with practice and patience you can get decent measurements with them.
Here is an interesting article on honing cylinders.

how would you use the vernier caliper to measure down into the cylinder?

that offers information on not having to rehone the cylinders when not boring the motor. it doesnt offer any info on checking the roundness of the cylinders

With these two items you can measure the dimensions of the bores for egging.

When I purchased my hone and stones, I also purchased a dial bore gauge to make sure that I didn't "over do it"...


-D.Idiot

ok now it makes sense. given slantsik's article im not gonna hone the cylinder but i would like to make sure its not too out of round and needing a bore before i go through the trouble of putting new parts in it. im going to get the bore gauge and borrow a caliper off of a friend.

thanks for the help guys. im sure im gonna have more questions when the parts come in and the motor is torn down.
