ok so by the end of this month i am planning to replace my piston rings and putting new headsuds and intake manifold at the same time. me and my dad just had a discussion about replacing the piston rings. he brought up a very major point that if i put the new ones on the top will automatically crack. so you are saying y would it crack its brand new. he said since im not sending the block to a machinist the groove on top of the wall will make the ring crack/brake watever. so my question is that if i do this will my new piston rings crack. when replacing the piston rings, is it necessary to send the block to get it rehoned (idk if propper term) to a machinist. what are the chances that my ring will crack. he is no mechanic but he had an expreince that did the same thing to him when he was a little older than me. i really dont want to send my block out i dont have that money for that kind of stuff. also on ebay i saw there was a tool to rehone the block should i use that? so give pick and give me advice on what i should do.
1. dont listen to him and replace it. and hope everything turns out perfect.
2. sell the car and include my parts for the buyer.
3. dont listen to him replace it and if it cracks sell the car.
thank hope you guys have some advice for me. (pick the first one)haha

You do don't have to rehone, but it is recommended especially if your cylinder walls don't have any crosshatch. There have been quite a few people who have just replaced the piston rings without any problems. But IMHO, I would just rehone the block, to ensure proper piston ring seal with the walls.

so you are saying send the block out to a machinist? or get that tool to get the carbon build up and pray it wont crack

Personally, I would send it out to a machinist.

Which tool are you referring to about doing the honning yourself? I've heard the stone type ones break and could cause more damage to the piston walls. But I have no first hand experiance with them. I believe there is another type of honing tool but I am not too familiar with it.

I guess you can do some more research on honing tools and if you feel comfortable doing it yourself then it is worth considering.

i dought there is a groove on my c wall that will make the rings crack. but my bro recemended to buy this tool on ebay to get rid of carbon build up. now i cant find this tool again im gonna have to ask him what exactly it is. i want more people to givet their two cents in this and if they still got smoke after the new rings. cause thats the reason im replacing them cause my car smokes. black smoke. white in the morning but thats cause of the weather.

you will not crack your new rings.
the tool you are refering to is a ridge reamer. what sometimes happens if you dont use it is that when pushing the piston out of the block the rings will catch at the top of the cylinder wall ridge. which if you just push on, can stress the ring lands on the piston and could damage the piston... this is while dissasembling the block.. it doesnt really matter when your putting it together. i STRONGLY recommend taking it to a shop to get it honed and decked.. the head also should be checked. let me know if you have any more questions..

oh and uh unless your headstuds are damaged you dont need to replace them they are not torque-to-yeild bolts. they can be reused.

also black smoke tends to be because of a RICH condition.. not oil burning...

burning oil=blue smoke..

how many miles on it?
before you go and waste time and money doing that you should do a leakdown test. it will tell you the condition of your rings and valves... and which need attention

my compression is low too forgot to mension that reason. if just you the ridge reamer will i be fine? also im planning on going turbo in the summer. so i thought getting new arp head studs would help.

toofast4u752

if your gonna boost it, just get it done right. take the block to the shop it wont be more than a couple hundred bucks. i put a motor together without machining it and it burn a quart of oil every other week. just do it right the first time. it will save you the trouble of having to pull the block and doing it over again. it happened to me and i wont ever do it again.

just do it right the first time ESPECIALLY if your going to run it hard and boost it... if anything forget the arp studs and use the money to machine the block.. im willing to bet that a properly machined block can hold more boost and last longer than a half-assed assembled block with arp studs. the studs dont do **** for you if your block is assembled shity.

im not going 500hp im staying 6-9 boost. and im not going past 8.5 rpm. a stock gsr block should hold that. im racing or competing i just want to have some fun sometimes at the track. thanks for the info i appreciate it

even at low boost you still need to be sure the block is assembled right.. a gsr can easily hold that boost but we all know honda assembled it RIGHT... if your just gonna slap new rings on and throw it back together it will not hold boost....
