Do You have a leakdown tester or compression tester w/a detachable hose that has a std. Milton or I/M quick disconnect? If so, take the light-springed schrader valve out, screw it in & plug the air hose on.It wont matter w/the rocker shafts off, if You put 100psi in there, there's 300+ pounds of force holding the intake closed..200# on the exhaust, piston up down, it won't matter. If You hook the stem hard enough to unseat one, You'll be dressing it for a good gouge/nick, that's for sure. Carefully stuff some paper towels to block keepers from escaping into the valley, then You can concentrate on the task, yeah it's not too late to get/build a better means of compressing the retainers...but it's frustrating to be there then stop to do so.....oh, a steady-handed helper is a plus for sure.
Thanks, great idea, I have one and removed gauge, looks like it might work, but why remove Schrader valve? If I remove it all the air will come out(like a tire)??
The schrader traps air in the hose/gauge, that means it only lets pressure out of the cyl., not in...just leave the air hose plugged on until that cylinder's finished & move to next.
. I called and asked if I could buy an old hyd rocker, he said to come look at his compressor and he'll dig out a rocker.
Glad You got that accomplished, now on to enjoying Yourself!!
Glad to help! Mine is ugly, but it is one of my most prized tools!Success! #1 intake done. #1 ex and int in ONLY 24 hours.
Thanks again @KnuckleDuster for the idea. Used a spark plug socket with the hex end for wrenches Double wrenched it and ez-pz.
I already had rope installed so left it while I did intake.
Next I'll do the air trick, thanks to @Killer6 I'll use the compression tester with some extra hardware I bought at hardware store.
Thanks folks!
