intake gasket is sweating coolant?
Ok just a update, i checked the heads, china walls and intake with a straight edge, no noticeable gaps, there was a very slight light gap when i got to the rear of the intake flange where the rear water ports would be, i could barely see light through in a spot but i doubt its even measurable with a feeler guage. The straight edge could also have a variance in it as well. Dry fit the intake on the engine, fit nice against the heads on both sides, no rock in the intake. bolt holes in the heads were about dead center in the holes on the intake, checked with a feeler guage and made sure the intake wasnt touching the china walls, i think i ended up with about .030 of gap between the intake and china wall with no gaskets. I threaded the 4 corner bolts in by hand until they bottomed out. I had about 1/2” from the head to the bottom of the washer on the bolt. The intake flange is just under 3/4” thick so i have about 3/16” of threads to bolt the intake down in the 4 corners not counting the 1/16” gasket. For good measure i added 1/16” thick washers between the bolt and hardened washer on the 4 corner bolts. I cleaned all the bolt holes with some brake cleaner on q tips and got them as clean as i could. Wire wheeled all the bolts clean. Went over the heads, china walls and intake flange with a piece of old red scotch brite and brake cleaner, wiped over all surfaces several times with the brake cleaner, applied a layer of the gasgacinch on the heads and on the head side of the gaskets. Applied a thin wipe of gray rtv around the water ports and then lined the gaskets up with the intake ports and bolt holes and stuck them on, put a good amount of gray rtv on the china walls overlapping onto the intake gaskets, put a thin wipe of rtv on the gaskets around the water ports. Set the intake on and lined up pretty close, had to shift it a little to the pass side to get the holes lined up, put thread sealant on all the bolts and the all threaded in without a problem. Ran them down until they just made contact with the intake, tightened the intake using the recommended sequence and went over them about 5 or 6 times tightening them gradually, gonna let it sit untill tomorrow night and then fill it with coolant, and cross my fingers. Have to redo the valve cover gaskets tomorrow, think im going to clearance the valve covers some more as well
