Sorry this thread has taken so many twists, I'll cover each issue;
 
Wastegate solenoid has 12 volts to the pink wire, solenoid must be bad? :013:
 
Oil leak.....its very small, coming out where the hose connects the turbo outlet to the intercooler.
 
controlling boost tuner style now, at about 13lb boost so I dont have to deal with knock while working on the WOT tranny issue.
 
I adjusted the TV cable per Steve's site instructions, tested it out while on the way to the shop this morning. I dont know if its when the converter locks up or when its shifting into overdrive but it would turn about 3000 rpms for a long time around 60 mph and then it would lunge into "high" and rpms would drop to 2000. I didnt like that lunge so I stopped and adjusted the TV cable back toward the firewall one notch. That seemed to be perfect.
 
Got to the shop and he hooked it up to a scan tool and we went for a spin. Normal driving and he said everything looked as it should. Got on a side road and hit it from a standstill and of course it performed flawlessly, pulled good in first and shifted good right when the first red light on the LED tach lit up, went through 2nd and 3rd and each time it shifted right when that first red light lit. Held 13lbs boost solidly all the way. Did this 3 times and each time it ran perfect. He said the scan tool never showed any problems. I can only speculate that whatever that cable hooks to in tranny wasnt operating properly and dicking around with the adjustment corrected it??? :icon_eyes:
 
On a side note, Steve might remember me chasing this issue. I thought it was making a lifter ticking noise since I bought the car, everyone told me to check drivers side header for cracks or leaks, none. This morning the guy said he thought it was piston slap, he said thats what it acted and sounded like to him? If that is the noise, its slight, he had a really hard time hearing it, should I be concerned?
 
Think that covers everything that has cropped up on this thread :chin:  Thanks for any and all help :icon_lol: , I didnt waht to start a different thread with each new issue!!

probably not piston slap with factory pistons...but, who knows for sure.  Tearing the engine apart might find a problem with a piston pin or something else, or it may not.  I quit worrying about noises even before I lost a lot of my hearing....

Long as it does not get louder, I would concentrate on the next problem in line...there usually is one. :)

Usually, you can hear the solenoid buzz when you ground it if it is working.

Yes, I'm done worrying about the tick noise.
 
I was thinking of getting an RJC boost controller and just eliminate the electric solenoid. Tuner style is ok, kinda lazy buildup, but I assume with the boost controller in line from what I've read boost will build similar to how it did using the solenoid.
 
Yeah, my car seems to create new problems every trip out :icon_lol:
