Repainting Throttle Body Cover
While my Z slept for 10 months awaiting her transmission, the antifreeze in her motor ate through the gasket and did a number on the finish as shown. I sanded off the damage part of the throttle body and use a paint that I got from Lingenfelter. That fixed that but how do I match the paint on the rest of the plenum? That's the question at the moment.

Re: Repainting Throttle Body Cover
Get rid of the paint issue, just start rubbing

Re: Repainting Throttle Body Cover
I'm sorry but that makes no sense. Rubbing with what? Specifically, what are you talking about? Roy

Re: Repainting Throttle Body Cover
If i were to guess, I'd say he meant to polish your LT5 like he showed in the pic.
Polished motors are pretty for sure, but I'd yuess it takes a ton of rubbng. Crabs

Re: Repainting Throttle Body Cover
Does anyone know, for sure, what product was used to paint the engines?

Re: Repainting Throttle Body Cover
The color may be hard to match, especially if you're considering NCRS. If not, I would have the plenum, cam covers, snorkel and throttle body powder coated and dress it up a bit, then it will all match.

Re: Repainting Throttle Body Cover
I agree with Joe. Contact Marc Haibeck about it. --Bob

Joe, not doing NCRS, I just want the throttle body to match up with the rest of the plenum. The color on the is the original color for that year as it was stored and then put in the body. It looks like a different color than my 92 was. Another thing is that Marc said don't powder coat the engine as it can warp the cam covers. He said to paint it. Roy

Re: Repainting Throttle Body Cover
I thought I would relay my own experience with this. I too, repainted my plenum cover with the Lingenfelter paint. Trying to do it correctly, I removed all traces of old gasket material and cleaned up coolant residue under the cover. I recut and used my own bulk gasket material of the same thickness. Inside two years, the paint lifted again.
THIS Time, after cleaning everything up and repainting, I used permatex (orange, I think) to coat my cut gasket material and then let it dry. I reassembled. That was 20 years ago and I haven't had a problem since with electrolysis, or whatever causes the lifting. And yes, this on a car, that still runs the coolant through the throttle body. As far as "match", for the fact that it was the Lingenfelter paint and somewhat close (but not perfect), I decided to leave it alone as is. Case in point, I seem to think that coating the material helped against electrolysis. I did not paint the underside of the cover (not that anyone would), but I think that is important too...not to give avenues for the electrolysis to travel if it gets under any paint and just continues on... I only painted the top and sides of the cover (masked off bottom). Hope my post makes sense and provides some degree of insight to someone. -Meanmyz. |
