Hi RichLo,
Thanks for the advice.
Today I ordered the parts, and will install them when they arrive.
Then the guy can run it for a week or so.
Then back to me to check on it.
I could not find any replacement parts for the intake leak.
Maybe you know a source where I can get them?
It's a 1998 Tahoe 5.7L Vortec intake adapter that mounts to the throttle-body.
I've done that (bringing everything back to OEM spec) on a badly butchered 2000 Silverado LS1 V8.
Did that 5 years ago, and the thing keeps on running and running w/o problems.
But this guy is different.
My thought was to get O2 emulators for the aft O2 sensors and get a guy to do a PCM update for the EGR system and tune it to the cam.
But first I need to learn the procedure for determining what cam is in it.
Not sure how to do that.
I think when the new plugs arrive, that'll fix the #3 mild misfire.
As for the intake adapter leak, I bought a couple Buna-N square seals that I can super-glue together so they will fill into that hole AND seal. But that's not as secure as the rubber-coated metal double lip seal that came from GM. Anyway, hopefully that'll fix the leak.
Cheers...
