Re-checked the compression, and you're right. Cylinders 2&3 are getting about 60-75, but 1-4 got up to 160. The truck will run on the two cylinders and actually doesn't sound as bad as i thought it would. (I disconnected spark plugs on 2 and 3 while it was running and no difference was made telling me that they for sure aren't firing). I put some oil in they cylinders and rechecked compression and it didn't make any difference, so would that rule rings out? Where should I start from here. Thanks again.
