Thread: 3800sc upper plenum leak

people do it all the time with ic installs. sounds odd that it would still leak with the gasket rtv'ed. that should have done it.

unless its a injector o ring sicking in the carb cleaner? or the boost by pass solenoid?

maybe smoke test it. then you'll know for sure.

Yeah I figured the gasket and rtv woulda sealed it up tight. Weird thing is I'm getting no smoke out that spot or bubbles from a soapy water solution. Only the carb cleaner makes it stumble, although this time it's not as bad all from the same spot.
