That is the best course of action.  One thing at a time...
Yes, one thing at a time, and as you can see in the photo the GN is up in the air again
I wanted to make sure when I use the smoke machine, by removing both front tires I can see headers crossover pipes flanges for no leaks.
The reason for this I was hearing a small ticking noise and I though possibly an exhaust leaks, the other could be the cam sensor.
I did replaced the cam sensor, checked for oil pressure (10#) was good enough to start the engine.
Nearly scare shit out of me when the engine started It sound like I had no oil and every bearings was singing
I immediate shut down, took a while to compose myself, and only thing I did was replaced the cam sensor. I removed the cam sensor and installed the brand new backup cam sensor. I removed the #1 spark plug and place a wine cork to find TDC, and let me tell you trying to move that little fan is no joke. Finally set the new cam sensor, rechecked the oil pressure again (#12) and the engine started with no problem and no noise.
The existing cam sensor that I removed and took apart, what I found the lower brass bearing closes to the worm gear was spinning freely.
After this is complete I will check again for vacuum leaks

I will stop by and put a bullet hole in the engine so you can find a leak!  Nothing less than that will convince you!

A lot of broken parts does not make you a racer; it makes you a slow learner.

Hi Steve,
 Well I finally installed the cam sensor, and I also replaced the shifter cable since the existing one was about 1/2" too long and that cable came from of the Buick Vendor.
The replacement I got from Amazon - ATP Y-651 Transhift Cable and fitted pretty good.
MAF translator settings as follow:
sw1-on, sw2-on, sw3-on, sw4-off, maf base#3
scanmaster readings:
02-675
AF-05
LB-35
BAT-13.4
INT-124
BL-124
NPH-0
CLT-176
ATS-121
R-725
TPS-.42
IAC-25
CC-140-249
NAL-0
OIL PRES-26
VAC-15.5
A/F-15.1-15.6
I drove it down the block, and it felted really good, but I didn't go WOT.
Washed the car and place it inside the garage as it started to rain, and this rain will continue until next week.
I will post in a couple of weeks of results
I really do appreciated all of your help :cheers:
