Thats about the most tolerable difference it should have.
Probaly a little more ring wear, or even a valve seal issue with that cylinder.
Does your car consume a bit of oil? Either way I would not be too too concerned over it... ill post my numbers real quick.
Ok, this is the drivers side... #1 is closest to the radiator.
Now the passenger side, where my issues are...
Now, what bothers me is that the whole passengers side is lower. This is with 126k or so on the engine. Uses about 1 quart of oil between changes, no noticable smoke out of the exhaust.
What I am wondering is about the timing of the cams. I have read (and im sure others have) that even from the factory they can be off as much as 6-8* wich would cause one side to have lower compression.
That doesnt help the fact that cylinder "2" and "4" are definatly showing wear, but it may bump the overall numbers up. Kind of dont think that the cam timing being off is an issue though, it put down some strong numbers for just bolt ons.
