Title: Piston Rings (eBay Dispute)
Post by: JamesV6CDX on 28 May 2010, 22:20:20
I sold a set of rings on ebay, gen GM, as I never used them on my astra.

Chap sent me a message, saying both compression rings are there for each piston - but there are no oil rings. He states there is only the "spring" for the oil ring.

Well.... I thought, there were two compression rings, and a "scraper" ring?

Here is a picture... please advise!

Is he trying it on, or is this genuine? If they are genuinely missing, I will refund him without question.

Over to you:

your pic from left to right looks like compression rings then the scrapper/spacer spring.you sometimes (generally speaking) have two thin rings above and below the spring.

see what others say...

Well if they are wrong, they can go back to the dealer!!!!!!

Too much time has elapsed to just take them back as unwanted - but if incorrectly supplied, that would be different...

My understanding of car pistion rings is that the oil scraper ring generally comprises of 3 parts.  Upper, flat ring, spring tensioer type ring, and lower flat ring.

If the two seperate rings are not compression rings then, its an incomplete 'set' as it were....

I would offer to readjust price accordingly, rather than offer full refund, post back, etc etc....

Thanks, Broocie and chaps... :)

I think, given the chaps limited English... I will not get into debate, and give him a refund with good grace  :D :y

a full set of piston rings consists of the following FOR EACH PISTON

top compression ring

2nd compression ring

oil control ring, comprising top ring, bottom ring and expander.

so for a four cylinder car, a complete set has 20 individual components.
