Initially I'll probably use the bleed-down method when I pressurize the halves of the engine. If it shows results I'll start looking for specifics. |
I must have got confused somewhere earlier. Yes soap is a great test. Obviously you know all about leak tests in your line of work. You don't need me to tell you that.
OK it sounds like the intake is totally ruled out, and the intake gaskets maybe not totally but very low probability. I agree the next step is pressure test the block and heads together and go from there.
One question on picture #1. The block deck seems to not be solid where the intake and heads mate up. Is that a drain path to the pan or what?
