Welder's penetrate deeper!!
you can rent at most auto part stores, and you can use a comp tester too. Some have a fitting like a shrader valve you can pump some air into, the gage will read, and theres your tester.
Did some homework... I'm learning a few things..
I am trying to get to my cam and i have removed all of the nuts on the top of the cover, it wont budge, so i got the motor hot (let a hair dryer blow through the cam shaft for about an hour) still wont budge. I (gently) tapped into the space where the cover meets the rest of the motor with a flathead to break up any liquid sealer and i can see all around the bottom of the cover, but it still wont slide up off the bolts... Any ideas?
