Should I add the one quart of ATF on top of the 6 quarts of oil? Should I drain it and run 5 quarts oil to 1 quart of ATF? Just want to be sure that I'm trying this the right way.

You can add the extra quart. It is not that critical and you are going to be keeping the revs low and the motor mostly idling. Higher revs, and it will throw the extra out.

Someone said STP. STP is a thick band aid for a very high mileage motor where the parts are worn out. The theory is that the extra thick oil helps fill the gaps. Also, STP is very 'sticky' and in fact most folks use a 50:50 mix of motor oil and STP as an engine assembly lubricant. STP has excellent film strength. However, you have an acute lifter problem (one or two) caused by crap stuck in the lifter, as opposed to a chronically worn out motor due to way too many miles.

Personally I don't care for WIX filters although for some obscure autos they are the only ones you can get. I also do not use Fram. I usually stick with Purolator or AC.

Also, the problem arose after he had the head off, and he acknowledged that some gasket detritus could have fallen inside. Since the problem followed, it is more likely that a piece of gasket material is at fault as opposed to a wiped cam lobe.
You can have a smooth idle with a bad cam. Now when a rocker is making has much noise as the OP is describing then either one or more of the following items are the cause cam itself worn down, push rod worn or bent, worn rocker or a bad lifter that is either worn or on the edge of failure.

Personally I would like to heard this noise before I would spend much more time in a discussion about it. With the fact that he can push down on the rocker to quieten it down real does not mean alot. It could be that him pushing is masking the loudness of said noise.

When I was younger ( in my teens ) I drove a car with and wiped out cam lobe Due to a stuck valve. Idle smooth ran ok . In fact drove it clear across the country ( west Texas to Fla to East Tenn. and back to TX )

A 89 yj with a 4.0 aw4 sye out of an 92xj. Now the hard part is done time to get it up in the air just a bit. Working on 8.8 with 3.73 and lsd for the rear. and new D30 hp with 3.73 .
For those who have not figured this out I'm old school but can handle the new too.

EZ way to confirm, as I believe the OP already has the valve cover loose.

OP, pull the cover and take the center wire out of the distributor cap so the engine cannot start. Crank the motor and observe the valve action. Do all of the intakes move (open) the same amount? Ditto for the exhausts. You will need to take the slack out of the loose pushrods. If yes, the cam is OK.

I just got back into to town and I've got the next couple of day to figure out whats up. I will go through the list, taking measurements, flushing with ATF, and I'll try to get a video up if the problem persist.

My question is, what would be a good way to disengage the fuel injectors or fuel system. I want to crank the motor with out it firing. I know you can just take off the center wire on the distributor, but that still leaves the injectors firing, which extended cranking can cause fuel pooling in the manifold or cylinder.

PDC is the fuse block under the hood and the cover has a list of all the relay and fuse locations.

Well, dumping a quart of ATF in the crankcase worked. After a few cold starts, and some prolonged idling, it quieted right up. Now it's running smooth and awsome. Thanks guys for your help, and preventing me from having to pull the head off. This site saved my a$$ once again.
