Just got finished putting on the intake manifold on my 06 wrx. I had to replace the turbo inlet and a pcv hose. Went for a test drive and the car is staying in vacuum. Cruising at max throttle reads -5.9psi steadily. It also is really hard to start, it takes some cranking over and pressing of the throttle but once it starts it idles and revs just fine. Some things that seem suspect:
-turbo isnt making any spooling noises at all. Its a td06 18g. I plan on removing DP or inlet to test the spindle. It seemed fine when i had the intake off.
- i forgot the gas cap was loose and it rained outside. Im not sure if any water got into the tank but it was at 1/4 and i filled it up and it made no difference at all.
- soke water got into my intake ports from the rain but the valves were shut and no water appeared to have entered the cylinders. However if it did maybe it fouled out my spark plugs and thats my power loss cause?
- lastly, i think i snapped one of the throttle body bolts. I was tightening it and it was tight then it just let go. I left it in there and didnt try to unscrew it yet. I dont think one busted throttle body bolt would cause a constant vacuum condition though.
So thats everything, let me know please what any of you guys think it could be. She ran like a champ before, only reason i took off the intake was to fix a leaking broke pcv tube and the turbo inlet and now this is happening.
