Quick update on my boost issue:
(1) I was talking to a few respectable people in the Z community about my issue and what they thought of it after explaining my situation to them.
My Situation:
- I forgot to mention to you guys that my OEM idler pulley (the one between the Crank pulley and the A/C? pulley?) is missing. It actually popped out of the engine while I was attempting a pull one night and was forever lost.
Why? Because the person who worked on the engine last and put that pulley in there screwed it up and tried to retap the threads but failed at it, causing my pulley to pop out of it's slot when I was doing a pull that night.
Solution?
We decided to find a different serpentine belt to wrap around the entire remaining pulleys to "compensate" for the missing OEM idler pulley. (See attached image of the blue circled pulley that popped out).
The car ran fine, but the boost was extremely low for what my set up was. I was making an average of 6 - 7 PSI after this solution was complete. And we had no idea why.
At first we thought maybe its the area that the car was driving in at the time? Nope , not that. At my area the PSI was around the same lol.
Fast forward 9 months later (today) and I'm talking to a few respected people regarding this issu. 3 people say it was belt slip, everyone else (5++) say it was boost leak.
I'm like uhh, okay maybe it's boost leak then if majority says~~
Then I forgot to mention to some of those people that I was missing an OEM idler pulley and I told them the same story I told you guys just now.
(See attached images for what they thought and what they think, and also for an image of the missing pulley that popped out).
Unfortunately I don't have an image of the way the engine is routed at the moment, but it is definitely causing belt slip on the serpentine side.
One of the guys in one of the screenshots explains why!
What do you guys think?
Thoughts? Comments?
In lieu of all of this, in 2 weeks, I am going to gather up the following items:
(1)- Front timing cover
(2)- Missing OEM Idler Pulley (+) Hardware
(3)- Upper Timing Cover Gasket (Left and Right)
(4)- Front Main Seal
(5)- RTV
(6)- K071040 Belt
(7)- K080220RPM belt
(8)- Brand new K&N Air Filter (Current one I have is busted somehow, and looks almost like a cup, lol)
Going to replace the timing cover for 2 reasons:
(1) Threads where OEM idler pulley is screwed up, which is originally why we could not replace an idler pulley at the time we replaced the new belt on there.
(2) There is a tiny oil leak on the front passenger side of the timing cover that needs to be addressed. =)
