Rb26 Compression Question

[XKLABA]

it won't be cam timing, they're mechanically spaced from cylinder to cylinder and as such will give even results across the board, dew to the inconsistency between cold and hot I would cold test all again then wet test then hot test incase the tester wasn't sealed in properly, and test all

but I would say from what i have read you will need to find someone that can do a leakdown test, if there is a valve issue like a small chip or crack in one valve it will still give some compression in a comp test, the leakdown will comfirm

to do a leakdown you need a compressor and a attachment to go between the hose that goes to the motor and the comp tester gauge that you can attach the compressor to, to do the test you need to find the point where both valve are shut, pump it to a set psi and then see how long it takes go drop to 0

I don't have a leak down tester that's the only reason I havnt done it yet, are they expensive ?

Google it and it will tell you how to make one or pay a workshop an hour's labour to do it for you.
