Good to hear the COME method worked for you. I've only ever heard positive feedback. The method he uses really makes sense when you are doing it. Every time you fit the crank and remove the cap to trim the seal you can see more of the sealer squeezing out from under the seal, which means it's really forcing the seal in against the cap, making a good seal. Took many shots to get it right, but yeah small price to pay for a dry rear seal. I hate oil leaks, it was the only leak this engine had and it bugged the **** out of me. Every time I was under the car I'd wipe the inspection cover clean and anything that had blown back to the gearbox, because the rest was dry
a couple of photos of it's current state at the moment
I also ended up replacing the oil pump drive gear as for many years I was running a JP High volume pump, until I found out the risks of drive gear and shaft failure. My old gear was showing some decent signs of wear, so I didn't take the risk. Over the shoulder and found a NOS gear (for extortion money...). Surprisingly the main bearings in particular were shot. Big ends weren't much better. Not sure if it has momentarily lost oil pressure at some stage on those track days. Also looking at some of the scoring on the bearings, I'd say when it wore the tips off the pushrods a while back, the abrasive particles went through the bearings. I plastigaged the crank journals on new bearing shells and the mains were measuring up around 076mm which is too much. Big ends weren't too bad but had a fair marks in them as well. So decided to get the crank machined and order some 020 oversize bearings. So if anyone wants some brand new 010 ACL race series bearings only fitted for measuring purposes, I've got a set here lol
Oil pump. It's a brand new JP std volume pump I bought for the engine recently. It's done less than 1000km, so it's in good order.
I'm going to generally follow TK's thread at the AV8 forum. But don't like the idea of removing the bypass valve.
So basically will be cleaning up all the galleries/ports and see if I can find someone to make up a shim so I can shim up the relief spring pressure.
