Re: Installing Throttle Body Plate, Broke a Bolt, now it leaks ---
How tight did you turn that bolt? They're pretty small to begin with. You can do the bypass or just block the passage making plenum removal so much easier.

Re: Installing Throttle Body Plate, Broke a Bolt, now it leaks ---
I guessed the M4.5 based on the bore diameters of the cover. I've one here that's 4.555 to 4.60 and it seemed the bore would more closely match the diameter of the bolt but after reading your post I checked and the "clearance" drill for an M4 is 4.5 I should have expected that probably because the M4.5 is only done in the Metric fine and that is very seldom ever used by GM. I thought the exception here might have been the Rochester Products Division.

I think the bolts were really corroded (a bunch of tan gunk on them). I probably overtightened it , but it still wasn't tight enough to keep the antifreeze from squirting out HAHAH. The new faceplate didn't have the groove in it like the factory plate, I am sure that doesn't help with sealing against the gasket that has the groove in it ---

Re: Installing Throttle Body Plate, Broke a Bolt, now it leaks ---
The plates are machined perfectly flat and as you noticed smooth providing a perfect seal on a new or reasonably good shape gasket. The corroded bolts have been an issue in the past but NEVER a sealing issue with my plates.
Glad you got the broken bolt out with minimal trouble. Take care

Glad you got it fixed.
50/50 mix of antifreeze and water will not burn.

Re: Installing Throttle Body Plate, Broke a Bolt, now it leaks ---
I did the Haibeck TB bypass.Even though its supposed to slip under the plenum I had to pull the plenum to get it in.I wanted this to be as subtle as possible so I put hoses on the TB nipples and ran them towards the bottom of the plenum.[IMG][/IMG][IMG][/IMG]

Re: Installing Throttle Body Plate, Broke a Bolt, now it leaks ---
Here is some info for your future consideration. Several of us have done coolant delete in the plenum after some info from Locobob (see post #31 if you are a paying member in the Registry and can pull up the old newsletters)
http://zr1.net/forum/showthread.php?t=11425&page=4 I love it years ago and never looked back. So easy and no mess to pull the plenum in two shakes (dry). Not for the NCRS guys of course.
