compression test ?
when you do a compression test , do you pull one plug at a time and the put it back in or can you leave the plug out and go to the next cylinder ,cause i left each plug out and went to the next cyl. and of course the motor turns over faster so i got a higher reading than the first time example pulled number one all other plugs still in 135lbs went through all other cylinders left all 8 plugs out and tested number 1 again 160lbs should i do one cylinder at a time one plug at a time?GLENN
you can do it if you know how it works

well, professionally you take all plugs out then test and that's how we do them at school but at my house, I take 1 out individually and put it back after each cyl test.You don't know what you've got til it's gone

those readings are perfect. the SBC book my dad has says within 6 PSI is perfect for SBC's, in general within 10% is ok.You don't know what you've got til it's gone
