Vortec Intake Leak
I've got a 97 Z71 with P0107, P0122, P1107, P1122. I replaced the TPS and cleaned the throttle body. When I pulled the throttle body off to clean it, the intake had a good bit of sludge...some wet oil...in it. I think I've probably got the notorious vortec intake leak again. I was thinking about doing this myself this time but i'm having a hard time finding a good DIY or sticky on any other sites. Anyone got any info?

Grab a service manual. I have the GM dealer manuals made by Helminc.com for my 98 gmc. I've done my intake gaskets alot. Though my truck has never set any codes.

Make sure you get the upgraded Fel-Pro gasket set. They redesigned some areas to help keep them from crushing and moving around. I did mine on my 99 Tahoe several years back and its not too bad of a job.

Its pretty straight forward unless you split the intake than it takes a bit of figuring. Any service manual should tell you the majority of it tho.

Unless you have a catch can,you will always see oil residue inside the intake.

The story turned funny when I got aggravated and started debating a new truck anyway. I was looking at it with the what's next philosophy and the fact that my family and job have totally out grown the truck anyway. So I went to look at new trucks and the damn thing spun a bearing getting off the interstate. I was passing a few cars with the rpm's way up there and got off the exit ramp to hear it knocking. I few years ago I had some oil pressure troubles and started running 20W-50 with a quart of lucas in it. It hadn't had any oil pressure issues since but I think I'd only put a bandage over an open chest wound. It held for a little while but I have no complaints. I beat the piss out of the truck for 8 years. My dad beat the piss out of it since 1997. It had a crap ton of miles on it and I got a new truck out of it. RIP.
