On leaks...
Unfortunately, the Southwest Airlines Flu Virus, Variant 1 (SWAFV1) knocked me out for a few days, but during my convalescence I did a virtual walk around of my engine (IO-360-A1B6) looking for possible manifold leaks -- I think I've identified a few that I should share:
1. Bad sniffle valve -- check ball gets stuck, and the "suck" doesn't close it cleanly and lets air in.
2. Manifold pressure tap -- 45? AN fitting on #3 Jug (YMMV), to a hose, to another AN fitting on to the transducer manifold, to another hose to EI system. If anything along this path leaks it's going to let air in. Use Loctite 565 on those NPT fittings.
3. Gaskets around the intake runners -- top and bottom.
4. Gasket between FI Servo and Intake plenum.
5. Then the more gross errors - cracked intakes, cracked intake plenum, etc.
Personally, I'm going to revisit #2 on my setup as I had discovered that one of the tygon hoses had popped off the Plasma III.
Cheers!
