So i just bought my vr4 about a month ago and about 2 weeks go by and i have coolant leaking.
Took off the exhaust manifold and found that the turbo to manifold gasket is pretty much wasted.
Can this be the cause of the coolant leak?

Only thing that should be running through your exhaust should be exhaust. No coolant will be in that area. Best idea is to pinpoint where the leak is coming from and repair as nessisary.

I pressure tested the system and found a mist of coolant coming from the exhaust port on the far right. Head gasket maybe?

Yeah, or the o-ring on the water pipe.

One or more exhaust studs on the cylinder head, do in fact go into the water jacket/come into contact with coolant.

If it's not leaking at the O-ring for the water pump crossover tube, or anywhere on the turbo coolant lines, or the sandwich plates for the oil filter (if your motor has that installed),

then look to the studs on the head.
