    For sure that's the right repair kit its a tricky business. My engine is on a stand and I still have skinned knuckles.

    I'm a bit irritated and confused just now because the long block isn't that old and I've found nearly 5 mm gap in the top piston ring of number 4. That can't be right can it? Who fitted these things?

    Yeah for real.

    What's your mechanic's opinion on the ring gap? My manual says 0.9 mm is the limit for end gap. A quick measure with calipers puts the bore at 94 mm which is big if the long block is an 1800 as supplied. New barrels/pistons do you think? I'll have to measure some more I guess.

    you seems to have mismatched parts.. yeh take a good look at everything, 5mm ring end gap is huge, wrong parts fitted there i'm afraid.

    Well it got a good measure up today (sorry for the thread hijack).

    The barrels are 1 mm oversize and just about at the wear limit. Ring gaps are all over spec but nothing like that one on number 4. And you're right DakDak this isn't from wear its from some dodgy engine builder using the wrong parts. A pro too.. So its new barrels and pistons for me. I wonder what else is wrong with this engine.

    Is that the ring gap in the barrell or just after you pulled the barrell from the piston?

    In the barrel. An inch from the bottom. No kidding.

    Does the 2nd ring have the same gap,is there obvious wear in the bore? do you run foam air filters and have you been on unsealed roads? I rebuilt a type 3 1600 quite a few years ago and the customer had a long dirt drive,the dust got in somewhere and wreaked havoc with the rings.

    So the plot thickens...
    Did a compression test on the weekend and all cylinders were 130psi, except number 3 which was 120psi. Not sure why the compressions are now good, but if the compressions are like that then I won't be needing to take the engine out - happy days!

    I keep thinking maybe on the weekend I accidently checked one cylinder twice, and the compression is still bad. But I'm sure that's just mind games and will confirm again this weekend that all is well. Will be happier once I've checked it again.

    With good compressions, I'm looking forward to doing my first full tune-up. Got the synchro and tacho in the mail so watch out carbies! Not sure about engine timing, so I've started another thread on that...

    Thanks for the feedback here guys. Your assistance gave me the confidence and allowed me to arrange the necessary jacks etc. so would've gove ahead with the removal had the compressions not suddenly gotten better.

    This looks like as good a spot as any...

    Whats the go with the "support bar vw 784" in bentley, engine and clutch, p5, fig 3-2? Obviously a support which is installed to hold the transmission when you drop the engine, but i'm sure most wouldn't do this? Are people just jacking the transmission? 1600 engine, 3 fin box, 73 bus btw

    I jacked this from a couple of months ago Mike. Just trying to keep things together.

    just put a small jack under the gearbox, that way there is no strain when the back support bar is removed

    Thought about using a ratchet strap onto the chassis?
