I would check cylinders around #8 and then see if #8 is in that range.
I would not ever bother tho.

Your symptoms are classic head gasket

OK so checklist:

1) Gurgling water fall sound on accelerate from a stop light: yes or no?

2) Coolant level falls and then rises after you stop the truck and take the cap off - yes or no

3) Misfire on 1,2,7,8

All these are HG issues.

 

I did a compression test on cylinder 8 today, it shows 130psi, what is cylinder compression should be?

 

you need to preasure your cooling system, the leak in the front of the engine could easily be a timing chain cover leaking a common problem.

 

Did you smell it to see what it is?

Just saying...

 

I bleed out air from the upper radiator hose (raised up tank, open bleeding screw, fill up coolant). I don't have white smoke from exhaust, I don't have milky oil, oil cap is clean as well. Doesn't seem like a blown head gasket?! I just don't know where my coolant goes to?

I'm wondering my radiator cap still holds 14psi, how do I test radiator cap? I see coolant out from the tank breathing tube sometimes, is this normal?

 

your radiator/recover bottle cap should hold 18psi, it can also be tested with a preasure tester. But they only cost $20 or so, depending on the age of your truck you may just want to replace it.

 

Man up and pull the heads.
Wishful thinking will not fix the truck.

I did the same thing for a few weeks.

White smoke - I had SOME.
Put in Barr's leaks and it went away.
Coolant LOSS - I had some
Hose pressure - I had a lot.

Misfile on Cylinder #1.

YOU have a crank in the head gasket between the water jacket
and the cylinder on #8. The crack is 1mm by .01 mm.
And, that's it.
Get to it.

Your life is going by and you are fretting.
Just deal with it.

crank typo
Should be crack.

Look at the spent head gasket on my pictures for the crack.
See if you can find it.
I can see it on one of my flickr pictures.

You'll undoubtly have that same crack.

Like old shoes the gaskets wear out.

Pull it apart and then you can brag about finding the crack and fixing it.
