I have a 92 AWD Plymouth Laser RS.

About a week ago my car started smoking and burning lots of oil out of both the exhaust and from under the hood. I did a compression test and the results are as follows, 4-1 150, 150, 150, 50. Yes, that is 50 in the first cylinder. My first though was piston is either cracked or has bad rings. I've been reading around and found that it could be valve seals or bent valves. Also read that timing off could cause bent valves, but i only have the problem in the 1st cylinder. Tonight i opened the oil cap while the car was running to dump some more oil in, and there was smoke just rolling out from the cap opening. This makes me think valves now. Anyone know if its pistons? Thats all i really need to know. I have another head i am working on now. The car still runs and gets me to work and back. Any input is greatly appreciated.

Thanks,
Travis
