With the stripped bolts in the doghouse, use some, not a ton, of black silicone on each layer, the intake, the powerplate ( both sides) and the doghouse. let it cure before starting and you will eliminate any potential leaks. Makes removal harder but if you do it right you should never have a reason to remove it again. Even if you take out a headgasket in the future you dont need to remove it to remove the intake.
That bolt on my car was stripped also, used the silicone and put a slightly longer bolt there and its all good.

Yes, the changed MAF did work much better. I wouldnt think O2's in the 790 area would create knock? I had to put the working powerlogger ECM back in my car so no logs, and the SM cycles slower without it, but the knock reading also jumps to high ( 5 to 7) numbers right away. I though real knock built slower.
other than tweeking the knock sensor, I also need to do a new search for ANYTHING that might be hitting/rattling or that is loose that it might be hearing.

Well, freshly cleaned and flow tested injectors and......same crap. Its definitely not a fuel delivery problem, and if its getting un metered air i have no idea where It could be coming from. When the knock shows up on SM, O2 is 790ish. I'm convinced its false and sensor is "hearing" something else. Next try will be some serious Teflon on half the knock sensor threads and instead of using torque wrench to 14 pounds just hand tight and try that. Have not switched the spark module yet, want to try this first. Then that. Running out of ideas. It runs so good with no boost, blms at 128, just really smooth and nice, starts great and idles smoothly...... I just don't get it

My best advise is read Steve's Vortex buicks site , beginning to end. If you have one of these and plan on running that kind of boost your life will be better if you understand the basics of these. You end up with 2 options, find a guy that knows these cars to work on it for you, or learn as much as you can and fix things yourself. The first option will be hard to find.
On your scanmaster readings, 875 is very rich to have a knock recall of 4 degrees.
Turn down the boost,, read the site, correct the basics. And go from there. People on here will help. Good luck!!

At 30 lbs boost. How bad was the knock and how long did you run it that way?

Pulled plugs in kids car, was hoping to find a couple really white ones. They all look fine to me. Top row is passenger side.. the front one looks a touch whiter than the rest.. was thinking maybe an injector or 2 might have some trash in them causing my problem from when I first fired the car, lines were pretty dirty I found out then when I was checking fuel pressure. I still might pull them and get them cleaned again just to rule it out. This cars O2 just run way to low when you lift off throttle. My car doesn't ....it drops to some 350-400 numbers, kids car drops to alot of below 50 numbers, sometimes it even reads zero.

I read that also, but today when I removed it to torque it in correctly, the threads had all cut through the Teflon, had to be grounding ok.....you would need a massive amount of Teflon to effect the grounding I would think

When I swap the ESC if that help can a guy get a replacement anywhere? I read a bunch and can't tell if they are available anymore

okay, didnt have time to swap modules yet. I did remove coil and bracket and torqued knock sensor to 14ft lbs. reduced fueling to 130, attached 2 logs. I dont know what to think as I think I can hear timing rattle with windows open as i did the runs but O2's on these runs are not lean.  ?? I need to get the module switched

I will try that and report back!! Thanks

turned up the boost, adjusted WOT fueling to 135, made a test run, attached files. was only pushing 10 lbs boost so turned up again, this time to 15 for a much shorter run. I think I put knock sensor back in to tight?? logs show knock but O2s are good....I think its false and I need to remove/reinstall knock sensor? Maybe replace it???

Its a real good time trying to use a torque wrench with that bracket in the way....I went with Steve's hand tight specification
