I was reading through the LSJ build guide for reference when it comes time to do motor work..... Im curious is to why they reused the piston rings.... I was planning on doing a rebuild and wanted to get new rods and pistons then it came to thought that would I need to bore the block out or can i get away with just rehoning the block and using new rings. info from people that have rebuilt there motors would be helpful cause I would like to make this like a weekend project.... but if worst comes to worst I will get a new block and stuff.

one other question was what are some other options for rods for the LSJ. I seen j-body performance has them but I just wanted to see if there was other options out there. I remember reading about someones signature and it said they have crower rods. So I was curious if crower did actually come out with rods for our motors.

sorry if this is a repost but info to what im looking for IMO should be in a sticky somewhere on the forums for everyone wondering this same question.

 

if the motor was never fired, you can reuse them

 

If you use differnet rings your cylinder walls need to be honed. If you use the stock ones they don't.

 

if you're serious about building your motor i would look into pistons and rods (aftermarket) for the 2.2L or 2.4L ecotecs... i.e. a stroker. I'm sure there would be hiccups along the way, but at the end of the day, the added displacement, in conjunction with the beast LSJ head would be well worth it.

 

bump for more insight

 

NEVER reuse piston rings. in taking them out using the piston ring remover you can and most likely will open the gap between the two ends of the ring and that can create problems. if your doing a complete build and you can afford it. spend the extra 30-50 bucks on new rings...

lol... guys your piston ring are constanly moving. they dont sit in one spot they twist around in the ring lands. so the wear shouldnt be constant on the rings. you will have more wear on the thrust side of the cylinder walls, but the rings shouldnt be out of round. PUT NEW RINGS IN. dont be cheap when it comes to a build. because you'll see it in the end.

 

Takin right from the build book.

"While the stock pistons need to be replaced,
the stock rings are more than ready to handle
big power."

You have to transfer them to the same piston and in the same order.

 

try this on for size.

say you have a motor, you just put pistons and rings in, fresh walls. never fired, never had the heads on, or head on. notice that said piston is in wrong.
what happens
you take the piston out, flip it around, and stick it back in.

does this require new rings?
ONLY if you mess them up.

 

thats what i thought. besides the fact that theres better rings out there besides the stockers

 

Does it say in the build book they reused them?Cause by reading that,it sounds like to me,there just using stock rings.Meaning,they go to the dealer and buy brand new stock rings,not reuse them.

No you dont have to replace the rings,bacause you arent removing the rings from the piston.
