An intake valve was stuck open. Luckily, it was directly under a spark plug hole. I was able to shoot in penetrating oil, and then finally carburetor cleaner to soak the valve overnight. I gave it a good tap with a wood dowel and snap! It released back in to place. Then it would stick open again on the next turn of the starter, tap, snap, repeat! Finally, it moved freely on its own. I got the inspection plate and hold down back on without removing any intake or exhaust manifolds. It appeared to me that all the intake valves had a brownish-gold film on them that I believe is residue from ethanol that was used before my switch over to only non-ethanol. I have some engine wash that I will mix with the oil to clean it all up. I understand you let it run for 2-3 hours and then drain it when it’s still hot (ouch!), then refill with new oil. The photo shows the valve stuck open.
Thank you to Lynn James for the help!

Well, I got in there without taking the manifolds off, but deeming it a successful after work venture decided to stop while happy, and admire the fact that I didn't ruin anything (yet) while drinking a cold beer.
The good news, I think, is that there are no broken parts lying around and nothing looks out of order. I need one of my helpers this weekend to turn it over while I watch to see what's going on or not going on. I'm worried that I'll have to remove a lifter, which means the manifolds would have to come off. Otherwise I'm not sure how you compress the springs. I imagine also I'll have to remove the head to get the valve out. Not sure yet. Anyway, here is a photo of the suspect area.

My 33 KA developed a clicking in the valve train while idling. It appears by looking through the spark plug hole that one valve is not opening. Initially I thought it was maybe a sticking lifter, but none of the miracle additives made a difference. It was hardly noticeable to the running condition.
My question is this. Is it possible to remove the valve inspection cover and do anything without removing, at a minimum, the intake manifold? I think I will remove the carburetor and the manifold that it sits on, but was hoping not to fight with the bolts that attach the intake and exhaust manifolds. The problem is in the driver's side rear of the engine.
Any help is appreciated, and thank you in advance!
Jeff
