atomicdog, it was reading just fine before the plenum blew. Dodge dude94, the clutch fan is completely fine, but i do remember that the bypass hose might have kinked itself. thats my project tomorrow. ham bone, no i did not pour any into the intake, but i have gotten all the air i can out. as for more info, it also has more pressure than normal, enough when hot to spew out the cap. it holds under reg pressure, so i know its high.
