Doesn't sound too good. Either you have a sticking valve, or some broken rings, or something else pretty major wrong.

I think you have a blown head gasket, with the fire ring blown out between 2 cylinders.
Good luck.

i found out the cam i had in the car was no good (i hope). the guy i bought the cam from said he had some problems with it eating lifters and ate som of the cam (lol)he never told me this until after the cam was installed. i will replace the cam tomrrow with a trick flow stage 1 cam. i hope this will solve my problems.
