Help with Oil Leak??

Does this mean I will need to loosen and retighten the nut and also retighten the stud that goes into the block? I did a compression test and have 175 across.

If you find that a stud did not hold its torque rating it is always worth a shot in trying to correct the stud install completly by . That doesn't mean it will work always but it is worth a shot if you can reinstall it correctly (stud and bolt) and torque back to its correct value.
This is a frustrating situation to be in because I believe it is due to the 1 by 1 HS install, I hope it works out though.

If they held the torque rating and if that rating is 85+ ft lbs you will have to pull the head, inspect and put in a new gasket to stop the leak becuase with the leak happening at max torque rating it just won't get better without causing more possible/expensive damage if you aren't careful.

Well it doesn't appear to be losing oil between oil changes and I don't see white smoke either. I hope it was oil that drip out during the 1 by 1 method.
I hope it's something else because don't like the idea of removing the head, $$$$$.

As for the head studs the instructions they come with are not as accurate as they should be in my opinion. Mostly being the torque rating on the nut and the stud, you can't just hand tighten down the studs. You do want to use your hand with a allen wrench but you want to make sure you give it a good turn to be sure it hits the bottom of the block/threads or the stud will back out just a bit. The word hand tighten is misleading and causing people not to put any pressure on them what so ever. If the stud doesn't hit the bottom to seat the chances of it backing out over time are pretty good.
Like I said I feel your pain and I hope you get it lined out.

This is the reason I made a thread on 'signs of improper HS install'https://www.evolutionm.net/forums/sh...d.php?t=148641
Looks like I might have to wait on the alky kit until I get this thing staighten out

Pictures below. If my coolant have oil does this mean that my Head gasket is shot even though compression is still good. Will reloosening the stud and tightening it help?
Thanks.

I'm sorry to be the bearer of bad news, but at this point you will need to replace the headgasket. I have only experienced this on one car i worked on and i had to replace the headgasket as it would not seal after trying to torque down the bolts again.

but thanks. By torque down you mean just re-torque the nut to XX lb vs loosening and re-tightening it?

Man those pics bring back bad memorys and look exactly like what I have seen. Especially seeing it on the Intake manifold support bracket.

Most likley you can verify it comming from the head by first inspecting around the entire valve cover to make sure it isn't leaking and then if you can't find a leak you can continue to inspect the lower head lip (front and back) from under the car visually with a light or on top of the car using a small mechanics mirror.
You should also inspect your cam gears to see if you have any oil leaking out the cam gear seals around the shaft, just a thought.
