View GarageGuys, searching for some opinions on this one. Just put new rings and bearings in the 202, have only had it out for a few short runs and i noticed coolant weeping out (only a tiny amount) from between the gasket and the block and sitting directly below plugs 2 and 3 on top of the block between the top of the side plates and the gasket/head.
The block was decked a little more when I had it honed for rings and the head im running has only done 2 months worth of occasional weekend driving since I last had that shaved. So, both surfaces should be flat and true. Used a monotorque head gasket, ARP head studs were torqued to 75 ft lb's. Studs were sealed using GMH sealant.
Since first noticing the leak I've done the following: compression test, all 6 pots @ 175ish psi. Plugs out, wound it over and no coolant came out the plug holes so this all says to me the gasket hasnt blown.
I torqued the studs to 80 ft lb's and dropped a bit of coolant and added water to thicken it up a little. Took it for another strap yesterday got back and inspected and no leak. I went and checked today when I got home and there is still just the slightest hint of green coolant showing between gasket and block under plug #3.
What the hell is going on? Nothing else has changed and I have never had this problem before. If I have to I will rip the head, inspect and try a new gasket. Or is this one of those things that can happen on occasion and should not be of major concern? The only other things I can think of are the block was not decked correctly, or maybe with the lesser original torque on the studs and a highly pressurized cooling system (i run a 20lb rad .cap) the coolant was simply being squeezed out past the gasket.
Im going to take it out tomorrow with a standard rad. cap and see what happens. In the meantime I could sure do with some feedback if anyone else has encountered this.
