I can't find a water leak and my snap-on pressure tester does not have a cap that fits my jegs radiator even though they say it uses a regular chevy radiator car, it doesn't. The water leak started when I put the old heads on then I got my new vortecs, water pump, intake, radiator hoses, had jegs warranty the radiator, new water neck and a new radiator cap and it still leaks. It looks like its coming from the front of the block but I cant see a crack, is there a way to test for it or something I can do that will make cracks show up?

You have steel mr gasket head gaskets?

Tear it down to the bare block and have a machine shop bake it and magnaflux it.

Add UV dye to the cooling system and use a black light, you'll find where its coming from. Otherwise you can attempt to magnaflux it in the car but that may be tough....

next, is the water coming from above or below the heads? may have broken the plastic gasket for thevortec intake gaskets. also look close at the water pump bolts, as the go staight into the water passage in the block.
