They are within 10 lbs of each other so I gues I am ok. I got 160 across the board on a high compression '69 head. And you take out all six of the plugs before testing so the motor spins freely. Now if I can finish putting everything back together.Д«y throttle wide open I guess you mean hold the petal to the floor while turning over the engine? I imagine that might seem like a silly question to some of you, but I just wanted to make sure. THAT is much more important than high readings (within reason of course). Ballard pointed out, you'll want them all pretty much the same. If, on the other hand, it does not rise then you've a good indication that it's a valve sealing issue.ДЄs Sr. If, after squirting oil into the cylinder, your compression rises then you know it's a ring related issue. If you find low compression pressure you'll want to determine whether valves or rings are contributing to the problem. Two low cylinders next to each other can indicate head gasket issues. You'll want to perform the compression check with a warm engine, ignition disabled, throttle wide open. for example if one is 80 and the rest are 135 approx then there are a couple of tests to do to see where the problem in that cylinder lie. ThanksД¬ompression readings should be in the 100 to 170 range, most important the readings should be within 10lbs of each other. Does anyone know what value range I should get when I do a compression test? I will be doing the test on a 73 TR6. Triumph TR6 - Compression Reading Evening all.
