| Before - when you said compression was fine...did you test all the cylinders? I only ask because so many times people test a couple holes and figure it's good...but it doesn't work that way. All holes must be tested... What makes you think it is your valves? I'm not convinced just because it holds 80 and goes no further that it is valves. Both rings and valves have to hold the compression. Just because it is at 80...doesn't prove either way WHY it is at 80, and given the only history I know about (incorrect installation of o-rings) I'd say it was rings. Have you tried putting oil in to that cylinder before doing the compression test and does it change the compresion value? Cars with washed rings often dip quite low and if you don't give them some oil from the top, they stay that way for a while even after operation. Hopefully you've changed your oil already. In my first post in this thread, that was mentioned (and filter!)... I think before you remove the heads you need to really prove what is actually wrong. If you haven't added some oil in to that cylinder before doing a compression test, you need to first do that and see what the end result is. If compression does not change, yeah, you've got some kind of problem. If it goes up a whole bunch, perhaps it was just all the oil was washed away by the fuel. Either way, you need to prove what is going on here if you haven't already done that... If you are going to tear it down to the short block, IMO it is easiest to simply remove the engine from the car and do the work on an engine stand. ALL your plugs fouled with oil - that's interesting. But based on the fact you've got this oil in or near the throttle bodies, it's sounding more likely to me that the oil is coming in with the air, not that the source is inside each cylinder. Obviously you need to identify where the oil leak is (or leaks are)...sounds like a nice mess now. :-) Oh well, live and learn. If you didn't get to take it all apart...you wouldn't get an opportunity to learn it. But remember before you tear it apart, right now you're just looking at possibly washed rings, and oil leaks somewhere. You need to do whatever you can to find out exactly what is wrong before you tear it down...
