AMC 360 help

Sorry for your loss.............
Now, all is not yet lost.
Theres a good chance that one or both valves in #2 are bent. But its not a for-sure thing.It needs to be proven, cause there is a slim chance that one is just not seating,due to varnish on the stem.

This is what I would do;
I would put #2 (passenger front) at TDC compression. I would pull the valve cover off. I would check the positions of the valves and the valve lash. If there is a sloppy loose arm, thats the problem valve.
So what we need to find out is if its bent or just stuck near closed. If the lash is more than about .150 down, its probably bent.If the lash is just about .150 or less, then it may just be stuck.
I'll tell you what has worked for me;
I have removed the rocker arm assy,and if there is an umbrella seal (or was at one time) I raise it or break it to allow the application of some deep-creep penetrating fluid. Then I leave it overnight.
The next day, I have injected air into the cylinder (piston at TDC compression, and anchored)and then tapped the valve stem a wee bit. You have to be careful to not drive the valve into the piston. If it was stuck, then after a few taps air pressure may drive the valve back up to the seat. If it does then I work the stem back and forth a few times. I listen to the sound that the valve makes when it returns to the seat. If it changes, as compression builds, then I know I'm getting somewhere.
If the valve sticks further and further down, I stop air-pressurizing, and move the piston down, to provide room. I dont bother going to coil-bind. If it doesn't come back with a few taps, it likely wont, and that spells tear-down time.
BTW, if you noticed a metalic noise during cranking, similar to a rod knock, but yet different; That's the sound a valve makes when it is slapped by a piston. Dont ask me how I know that,lol!
