In the quest to solve my overheating problem I’m doing a compression test. WTF am I doing wrong??
It’s been awhile since I’ve used a compression gauge…I had a handheld tester that you just hold up to the plug hole…the tip was rubber…you just jammed it in there and have someone crank the engine a couple times. Boom, instant result. Accurate too. The tester I “borrowed” from AZone is the screw in variety which everyone uses.
The instructions say “remove all spark plugs, set at WOT. Remove the coil wire, screw in the tester nozzle, crank engine. I did just that. The results I get say exactly 90 psi across the board…all 6, no variation. Since the truck runs and idles fine, doesn’t smoke, and has power…I’m thinking the results are in error.
What am I doing wrong or is my truck so f***ed up that for some reason ALL my cylinders are running at 90 psi??
