Re: really really wierd.
Sorry to bring up this thread again, but after rebuilding my motor in the EA, including the timing chain and tensioners, I found that my o ring was sucked in as well, on both motors (mine and the one from the wreckers) In the kit I had, there was 2 different o rings supplied. One was like the one that was in the timing case, and the other was a thinner one. I installed the thinner one, as I had remembered this thread and others having the same problem. I found the thick one would squash too much and I feel that this is why it gets sucked in, cause that hole is the only place it can expand into. It also moves round in its hole, ie. its not held in place while the case is replaced. I fitted the thin one as this one went around the inside edge of the hole and fitted perfectly so it wont fall out when putting the case on the motor, it shouldn't suck into the hole as it wont squash down, and it just sticks out a bit further than the case so it should seal well.
Just wanted to post this to see what everyone else thought about this and maybe to help people with choosing the right o ring to put in. It's about half as thick as the one's that i found installed and a little bit larger in diameter....
