Apply silicone to the outside of the area to be sealed. push the sealer in with your finger and try and remove excess sealer.

Give plenty of cure time 48-72 hours. Now apply a coat of paint, spray bomb works the best. don't be shy and make sure to cover the whole area. The paint will keep the weeping to a min.


I like the 48-72 hours for cure time.

I like the part about the paint keeping the weep down...

When I worked for GM, they had this problem on some S10 pickups, they leaked on the front of the pan, on a u shaped area.
Dropping the pan required pulling the motor, so GM had a bulletin to use a sharp chisel to cut out the protruding RTV, the clean the surface and apply a fresh bead. We did this on several trucks and it worked like a charm!
I guess some people just like to spend extra money to make them feel warm and fuzzy that the job was done fully, I'm just making the point that you don't always have to blow 2 week worth of pay to solve the problem!


To fix this properly required more time and money,I'm glad it worked lke a charm, but I wouldn't have been standing in line to buy those vehicles with this fix.

The RTV is the gasket.
