    So on the last invoice I have it says special sc500 with a part number 08-502900-00 price per set is £46 including vat. Now if anyone has problems ordering these from GSF let Me know as I'll get a few sets and just sell them at cost plus postage.

    Just phoned GSF and gave them the part number n it's not one of theirs. So they looked at one of their outside suppliers and found them but apparently they're out of stock and have superseded.

    Ok, so after quite a few pms over the GSF piston rings and people not being able to order them from GSF I have just ordered 5 sets from GSF with collection tomorrow. Lemons3 has taken a set so have 4 others up for sale. I'm not making any money on them cos I'm nice like that :) rings are £46 per set. Postage £3.50 recorded. £1 per set for fuel for me to collect and visit post office. Total is £50.50. PayPal is good as long as fees covered. Pm with your interested.

    Positions are quite important too I think but I dont know where the ring gaps should go for each ring.

    On your crank to block

    Involves lots more bolt replacement and is a pita with having to remove the crank pulley which is bloody tight

    Just thought I'd plant the seed lol ;)

    Yeah but does it matter where you start? For example, bottom ring gap is at 12 o'clock on the piston, middle ring is 5 o'clock, top ring 9 o'clock.

    Ooops lol ;)

    But to be honest mate not worth doing them as it is such an agro to do, i would omly change them if removing the crank for a rebore or something

    iirc think the ring positioning on 1.8t's was 120 degrees rotation so would be 12, 4 and 8 oclock but will check elsa when at work tommorrow as left the car/work laptop at work.... Doh

    You may well need a diamond tipped needle file to gap the rings as when we was doing mine my normal needle files werent touching them and would have taken all day to file them down as they're rather hard and luckily managed to borrow a file off of a local engineering firm :)

    I've rebuilt two, and both didnt need the rings gapped. The rings were already the right size.

    Just space them into three parts (120 degrees), that's what I've always done.

    Do I HAVE to use a set of piston ring pliers to fit these or can they be done by hand?

    Just looking at the oil scrapper rings the set on the left, they look completely different to the stock ones and ones I've used. Not saying yours wont work, as I don't know that but they look a different type.

    Stock ones are a metal U shaped ring that has a metal spring like coil with a wire running through the middle. That one above looks like the scrunched up Zigzag style with a ring underneath.

    Like I say, not saying it wont work, just different.

    And in answer to your question. A piston ring tool is good to use but it can certainly be done perfectly well without one.

    I bought mahle ones, and they had the U shape and spring arrangement.

    I'd seriously suggest using pliers. The rings are hardened steel and the pistons are very soft alloy, mash them together trying to prize the ring on and you'll easily take gouges out of the piston.

    I have a set of these:
