Thanks. Probably just some remaining spill.

X2 on the "all or nothing" thinking. Unless you didn't tighten your valve cover down..... hehe
am I too late?
you cant adjust the valves while the engine's running.
you should set it hot.
i mean hot, work fast.
factoey spek is .008/.012 int./ex.
you should use that spec with firm drag on the feeler gauge.
or, my preffered method:
.007/.011 in/ex
with a tight fit.
works best
A fuel filter is also a thing that should be considered for replacement.
use factory or wix.
fram is junk.
search 4crawler.com for easy to read TPS adjustments.
NGK 1233 Plugs.
Short your TE1 and E1 connectors and set the timing to 8 deg BTDC
or is it 5?
better check into that...
you should use a gasket holder, like Gasga-Cinch instead of RTV. For the half moons.
Nuthin wrong with RTV, just makes it easier to install, and remove later on.
as far as the leak goes, you may have pinchedthe valve cover gasket.

Pin:
Your valve trick does not make sense. If you have a firm drag with a .008/.012 that would not equate to a tight fit with a .007/.011. Maybe you meant tight on the .008/.012 and firm on the .007/.011?
I did not use any RTV on the half moons. I set both of them in the head and then set the valve cover on top. I made sure that the top pf the half moon was aligned precisely with the horizontal of the head i.e. the mating surface for the valve cover.

I mean the .008/.012 should be loose
and the .007/.011 should feel tight.
that better?
ughh.
i could show you so much easier than i could explain.
try it the .007/.011 way, see what happens

Makes sense now. Thanks for the clarity.

Still working on that tank of gas. I am at 100 miles at 3/4 of a tank from a fill of 14 gallons. No A/C.
I am guessing at 300 miles on a tank for 13-13.5 gallons at this point. That should put me at about 23mpg. That would represent a significant increase.
I'll run the tank out in a couple of days.
Getting kind of obsessed with all this ( :

Alright, the numbers are in for the first tank.
276 miles with a fill up of 12.5 gallons = 22.08 mpg.
This represents a 16% increase in fuel economy (from 19 to 22 mpg). Now, at this point, I will have 300.00 into the 02 sensor and 0.00 into the valve adjustment. The O2 sensor should only be 100.00 from CDAN BUT the dumb ass prior owner welded the OE sensor to the cross pipe so I had to end up buying another crosspipe. I do not want to even think about how much a dealer would have charged for a valve adjustment.
So, at a 3mpg gain and a 300.00 spend, I will make up the money in ( I will not bore you with the formula)
15,000 miles.....Damn.
Should be though, at 100.00, ..........5000 miles. Not too bad there.
Since this truck is going to be my semi daily driver, I will put 15000 miles on her in about two years. For me, this is a VERY long term investment within these variables. However, a new 02 sensor and valve adjustment should also increase the life of other components but it is impossible to formulate that in this equation.
Step two coming next.

Thanks for the numbers, even though the 15,000 one kind of sucks..... My MPG just jumped from 18 to 20 on the last tank, and I didn't do anything different........ We'll see if it stays at 20....

Logged a 24.5 mpg on a trip this weekend to Northern OH. ALL highway miles minus a couple of miles off the interstate.

My muffler, literally, blew out on my end as if it was a glued in pancake. Pretty odd. For a couple of days, it was like I was driving a honda civic race car (noise wise at least). The prior owner had exhaust work done but man was it s***ty. So, I went back to a complete OE setup. During this, the fellow noticed a manifold noise and located a loose bolt and consequently a leaking point in the exhaust.
All new exhaust now and tightened manifold bolts. It is SOOOOOOOO quiet I cannot believe it. Looking to get another 1mpg out of this considering the manifold leak.
Stay tuned.
