I think Nitrostanggirl has u in the right direction, even though that is not what u want to hear...sorry dude. Have u drained the oil and looked at it, looked to see if there was any metal in the pan? One of the guys on here wrote a great post on vacuum tests (which I copied into a diagnosis folder), but I can not remember who posted it so I can give credit where it is due. In that post, I am under the impression the vacuum test will help tell if it is rings or not, but I am not sure if it tells u all your rings are bad...or can help tell if just cylinder #5 is bad.
How many miles are on the engine?
