hrmm.... did you take the 12mm bolt out of the back of the engine to make sure the rear balance shaft was in time? (you can slide a crwe driver through the hole)

ya the first time, but the cam caps i put on where wrong so i took them back off and retimed it again, so i think the valves are messed up again, but they could have been before i even put the new head in, not sure

yeah it'd be kind of weird to have some compression in 1 cylinder but not 3 other, especially since 1 & 4 and 2 & 3 rotate together. You can take the head off, make sure all the valves are closed, turn the head upside down, pour water in each combustion chamber and see if it leaks through over a period of an hour or so. That is a "quick" easy and diy way of checking without any special tools to make sure all the valves are seating.

ya, the head had alot of corrostion on it when i got it but i got most of it off, looked like some was holding the valves open a bit but i cleaned it out and it wasnt doing it anymore, i could do that though and thought about it but was trying to get around that, but i spose i gotta right, well ill do that this weekend shouldnt take long, but ya i thought it odd to have compression in the #3 and not the number 2

remove the lifters and manually collapse them in a vice until you are able to compress them with your thumb and index finger. then reinstall. this will need to be done any time you remove the cams. stupid i know, but go ahead and do this and let us know the deal. it can be done without removing the timing belt if youre really good.
