My rings went last night on my h22a4 block... im going to replace them but im also thinking of replacing the rods , pistons and bearings but my problem is my block has no oil squirters ..can that be the cause of my rings? Jw and also does any one know what kind of pistons can handle a block with no oil squirters?

Why were the oil squirters removed? The help cool the pistons. Not sure that it would have anything to do with your rings or not. You will be able to tell for sure once you tear the block down what the cause was. Could be your piston ring lands that went......
If your block is still running stock FRM sleeves. The only piston and rings that will work in your block are the ones that are made for FRM sleeves. OEM H22 or Mahle are your choices.Last edited by GhostAccord; 03-27-2012, 01:02 PM. -
I bought the car years ago off a friend it had an h23 head with a h22a4 block i think thats why he took out the oil squirters .. But the car ran perfect and fast.. I was wondering will these pistons work http://item.mobileweb.ebay.com/viewi...id=58531354785Comment

I don't see why they wouldn't work, the description lists everything. It mentions a Teflon coated side skirt but nothing about being FRM compatible. I guess you would ether have to ask them. Or assume that they are compatible. Just remember, you usually only get what you pay for! When it comes to internals and tuning, cheap is very rarely the best option.
Not sure why putting an H23 head would require removing the oil squirters, but too each his own. I would put them back in if it was my block. I always wondered why people removed them. I don't see any benefits. Unless you are sleeving the block or going for a longer stroke. Then you have to remove them.Comment

Yeah i just talkd to the seller he said there frm compatible. but that you need to hone your block lol ..i guess im going to have to pass on those pistons .... Im just going to stick with oem pistons with lighter rodsComment

I'd be careful how far I trusted the seller in that respect. But if your rings went out on FRM sleeves I'd open it up and check it out before I ordered anything. If you have gouges in your walls then you need to resleeve or get a new bottom end.My Members' Ride Thread - It's a marathon build, not a sprint. But keep me honest on the update frequency!Comment

also, if the rings went due to the sleeve surface being worn. You will probably need to go up to a set of OEM 0.25mm OS pistons and a proper FRM hone anyway. Not just any hone will do! A shop that regularly works on Porsche engines will know what they are doing.Comment

ive opened up a worn h22a4 block and the sleeves were toasted. not even going .010/.25mm over would clean it up. just a little precaution.Comment

I'm with those guys. What I would recommend as another option is using Darton Replacement Sleeves. Supposedly I've heard they're OEM strength or slightly better. You could go forged pistons and have more power when you drop it back in.'94 JDM H22A: 178whp 146wtq

White smoke is coolant not oil. Should do a compression test on your cylinders and or a cooling system pressure check.Comment

Will do , if it was coolant will it cause it 2 overheat? my temp seems preatty normalComment
