Yes, remove the rocker shaft. However before you do that you should be able to easily make this happen. Pull all the plugs to make it easy to rotate the engine. If you can rotate the engine by hand...

Excellent on the oil pressure. You are narrowing it down now. The cylinders with the low compression are probably the culprit. When the piston strikes the valve it can bend it. This usually causes a...
monty509, before I say the numbers look bad, we need to know your process. How did you perform the test? You need to follow the service manual. On a cold engine and in general, we are looking for the...
monty509, I see it still knocks with the clutch depressed. I am thinking its internal. You have run the gambit on everything I can think of. Can you run a compression check? It is the last step...
Wow I thought we had it. What happens when you push in the clutch? Lets be sure it isn't the clutch. Depressing the clutch will also put a little thrust on the crank. Lets see if that changes...
Definitely not firing very hot on that plug. Those chips in the porcelain are kind of weird. I take it this is the only plug with these chips in the porcelain? Maybe a defect? Well can't wait to see...
A chip on the insulator is not good. The smell of gas, also not good. I think you have it fixed now. "Eagle Eye TJones" is the man!
Needless to say we all await in great anticipation, the results...
My God Tim, how did you see that!? Definitely, you found it. The plug is grounding to the block. The arc is traveling down the electrode and across to ground on the block. We are hearing the fuel...
TJ what an eye! I went back and looked and thought the same thing, it looks like an arc on number one. Closer inspection and I think it's a piece of paper or tape flipping around.

I was thinking maybe a wrist pin also gm. I just can't see it coming and going like that. I think you may have something with the RPM gm. monty509, does it always go away at higher RPM? If it is a...
That sounds like you may have a load of carbon or water in the cylinder. The sound of it seems like one or two cylinders. What is the condition of the engine? A lot of hours? Does it burn any oil?...
