Intake manifold leak. Mechanic says don't fix
#21
It's leaking out of the front center of the LIM? I've not heard that one before. Though on the other hand, I am vastly under experienced when it comes to many others on this forum...so what I've heard and not heard is probably not worth a lot. It is right next to the coolant hose, so I maybe it would travel down that skinny little ledge to come out the middle. Just stirkes me as a little odd
Are you sure it's not the water pump? Coolant ends up in some weird places when the pump is going, going, gone.

but by now it's probably just the stuff I've been adding peak n peak (I did the radiator last February and since it's been losing antifreeze)Here's a pic

The black stuff is RTV. In the center, it seals oil, not coolant. If you're seeing coolant there, it's probably travelling from one of the corners of the intake manifold where the coolant passages are, (Under the AC compressor, and behind/below the alternator).

Looked like it was coming from by the alternator. So RTV good bad? He told me it was to seal the leaks in the intake gasket I don't have any oil leaks (never did)

The RTV is supposed to be there. It seals the top of the block to the intake manifold between the cylinder heads. The RTV only seals oil, not coolant or vacuum. The actual intake gaskets go between the heads and the lower intake manifold.
