[yorke58]

Hi

I have a jdm h22a, does any 1 know where to get the correct piston rings. Ive ordered stardard rings but the gaps are incorrect.

Incorrect as in too tight?

Yep, if too tight you can file the ends to open up the gap.

If too large, then I presume you have oversize pistons? If so you'd need to source oversize rings.

No experience of this make of rings at all (Hastings), but here's one source for standard/oversize/double oversize rings:

They show as out of stock, but contact them and they may be able to get them in?

Or these guys:

If you contact these guys, they may be able to get you Mahle rings.

You probably know this already, but be careful to get the right kind of rings - whether for the OEM block, or a cast iron/ductile iron lined block (if you've had that done).

nb: vtecmec knows far more relevant detail for H22 rings, than me!

Ive measured the bores and the piston and there 87 mm and the rings ive got are to large i can get a 0.80 feeler guage in.


The original rings fit and can tell they are original. I ordered standard rings for 87mm. Ive done little googling and it looks as though the H22a are different?

The block must be lined cos the engine shop i took it to couldnt hone it as its lined. But can tell its original.

Its a H22a 1150095 bbbb

Thanks for help and anymore

Cheers

B pistons are slightly smaller than A pistons so that might explain the gap. Might be best if you check with Honda and see if they can supply.
Info from HondaTech
A 86.993-87.006
B 86.983-86.996

Hope this helps.
Also I would double check with machine shop - the bores have frm liners from the factory and this is hard as hell hence worn rings.

Ive placed the new rings in the bores only, wirhout any pistons,and still have a big gap compared the the old ones. When you lay new and old rings on top of each other the new rings have a bigger gap but same diameter.

It looks as though the rings ive got are incorrect for a h22a. Ive just checked the new rings and it looks as though there for a A2 or A4. I just cant find rings just for H22A.

I might have to ring honda as youve said. With hard bores i want them to be right

Cheers
