There is a coolant passage in the bottom of the TB. Did it look like any was in the intake tract?

i just had to take my TB back off cause i put the tps on wrong and i did have coolant in my air way (where the air from the air box to the */c it was in the */c) now what does that mean? maybe a bad TB gasket?

Maybe. Has it run since you put it back on?

Eh, my guess would be the TB gasket or loose TB bolts.

when i put it back on i put rtv around the gasket just enough to seal better but not to much were it will interfere with flow. when i do my */c coupler ill find out if it is still leaking.

If it'* leaking..you'll be burning coolant.

Did you clean the gasket surfaces well before reinstalling the new gasket?

On the RTV, I used to use it on everything that looked like it could use a dab. Over the years and working with my mechanic buddy I learned that adding RTV to anything is adding another cleaning from he ll in the future. The factory assembled many gaskets dry and they work 100% for years. You can do the same unless the directions specifically call for RTV. To make your job cheaper and easier.. don't use RTV if it didn't exist there to begin with.
