180 Compression in 3 Cylinders!!!! HELP!!!

[19Eclipse90]

But 0 in the other. I don't have a clue what could be left. The head just had a valve job done. From the front of the engine it is the second cylinder. This is on my N/T, though I don't think it makes that much of a difference. It doesn't make sense to me because even a leaky valve, rings, or crack would give a reading of compression but gradually would go down. This cylinder is flat out reading 0. I talked to the guy that did the head and he said that the valves are definitely not leaking but check the rocker arms. I don't know what there is to check with the rocker arms, so I called another engine head who said that the springs if not seated correctly can keep a valve open a bit. Even so, all of the air isn't going to leak out immediately. He also mentioned the head bolts stretching and what not but that's not an issue as they have been re-torqued. I don't know what else to look at. There aren't any gaping holes anywhere and the piston is still in there as well as all the valves. Someone point me in the right direction! TIA

Edit: I don't remember what the problem was here. The head looks great to this day. But this car was swapped to turbo using a '91 engine, transmission, harness, and ECU within the following year.

0 usually indicates open or bent valves, take it back to the shop.

They shouldn't be bent but then I've never dealt with bent valves before. When people say bent valves I visualize like a 90 degree bend or something like that. Can you always tell with the naked eye if valves are bent or not?
How else would they be open?

do not reuse head bolts,their only good for one time

Thanks buddy but the head bolts are not the concern here.

Do a leak down test to find where you're losing compression. 0 Psi usually means bent intake or exhaust valves, hardly ever rings. A bent valve doesn't have to be bent that severly to give you 0 compression. I've pulled off heads before with bad valves and they 'visually' looked ok. Removing the valves and rolling them on a flat surface is one way to tell.

The reason why he had mentioned not to reuse headbolts is because it could cause your 0 compression if your reusing them, since they may not sit right. Although 1G headbolts aren't torque-to-yeild like they are on a 2G, it's still never recommended to reuse them.
