Funny you say that I also read do one at a time and keep other plugs in . Other than spark plug 4 we pulled all plugs to compression check 1 , 2 , and 3. So when we did those no spark plugs were installed . Didn’t make a difference really . We also didn’t warm the motor up like we are supposed to .
I wanted to mention after I get it running right (hoping to put the new gaskets on today) I plan to do a new test on a warmed up engine both dry and with oil. Seems healthy enough so far :) hoping it does well
@@mikhailSRT4 yeah I didn’t see the logic either . I think though that if say there is a head gasket leak from cylibder 4 to 3 and you pull the spark plug out of 3 to test 4 it would measure worse than if cylinder 3 had a plug . But at that point it’s clear something is wrong so what would be the point . I’ll have to test both ways and compare just to bust whatever myth is going on out there :)
Ur supposed to take all the spark plugs out then do compression test

Not true , plugs won't affect the compression. Cus gasses escape from the intake and exhaust .
