Miller Trailblazer 55G further questions...stuck valve
Gunner wrote:
Ive found that several of the valves were stuck as a result of rust...and with a bit of lifting and tapping managed to free all of them, except #1 intake valve, which is closed and stuck tighter than an 80 yr old nun. I backed off the tappet adjustment, to get enough room to put the tip of a screw driver between the valve stem and the lifter..no movement Tapped on the screw driver..no movement. Banged on the screw driver with a small hammer trying to wedge it upwards...no movement Now what? Use a cold chisel as a big wedge and a bigger hammer? I worry about dinging the adjuster, the cam lifter and the cam lobe Any suggestions would be appreciated. And yep..the engine is still frozen. Ill pull all the valves next week..assuming I can get this bitch loose and see if I can turn over the engine..if not..Ill have to drop the pan and drive the pistons up and out Gunner Try some Kroil and some patience ..

Grant The valve is in the full down position, and its been liberally G soaked with PBlaster for over 2 weeks, by spraying and keeping a puddle of said penetrant on the valve/block juncture Gunner |
