is it of big concern to have a compression test show 25 psi diff between the best cylinder and the worst? i have a 2000 4runner and the powertrain warranty is almost up, i mentioned this to the dealer and they dont seem concerned abou it at all. called toyota canada and they cant offer any info. What do you guys think? the lowest cylinder is 150psi while most of the others are around 175psi- 165psi. Do i have a case or is this not even really a big deal?

 

is that a wet test or a dry one?

 

that was a dry test i beleive... i dont know for sure- it was done by the dealership

 

10% (17psi) is generally considered maximum variance.
