no that is routed to the vaccume port that WAS capped on the passenger side of the intake.. we popped that (where u normally would put a vaccume gage on...) and put it there.

That is your problem then.Originally Posted by MidwestSS
The PCV goes to vac, but the passenger side should be free air. Actually it should be free metered air.
What you are doing with it the way you have it it pulling vac on both sides. You are effectively sucking all the air out the crankcase, and once the engine is off it is equalizing , hence the squealing.
Either put a filter on the passenger cover or on the line, or better yet, plumb that line into your intake tube after the MAF.
i used fuel filter with the part number Corvette filter/regulator Wix 33737 and it worked just fine and if you look in the end of the filter the holes are different sizes i dont think they can be backwards, i used a nick williams 92mm throttle body, as far a gains i made 22 rwhp and 9 rwtq oh and i did pacesetter longtubes with the swap so them number are intake and longtubes so im not too sure its worth it

I thought both valve covers needed vaccum.... i knew the pcv did, assumed other side did too. When we just had it open, the truck was going super lean, it is holding 14.7 with it hooked up as it is. We could hook it up to the intake tube easy enough.
blown transmissions are about as useful as 97% of the guys on this forum
No the passenger side is the air intake for the PCV and the driver's side is where it gets sucked out by the manifold VAC.
The reason it is going lean with it unplugged is that you are pulling in air through the PCV that is not metered by the MAF. Plumb it to the intake tube and you won't have that problem.
Look at this picture below of an intake like your original 2003:
Notice there is a separate air path from in front of the TB for the port the passenger valve cover line ran to.
Here you can see the point where the air is pulled from the TB, in front of the blade:
Since it is in front of the TB it is free air, not VAC. But it is still metered air since it is after the MAF. You can duplicate this set up by plumbing the passenger valve cover line into the intake tube.

ok stopped off at the Zone and found a 90 degree pcv elbow for a chrysler that fit in the top of the intake and free aired the passenger side valve cover... until we put it into the intake tube
