I just recently had my 3VZE out of my '89 Runner for a dropped valve seat. I decided to pull the bottom end also to freshen up all the gaskets and look things over.

The motor had been out at sometime in it's life and some snapperhead had the pan off. They must have used 4 tubes of RTV on the pan when they put it back on.

Be careful how much sealant you put on, as too much is a bad thing. In my motor it had migrated throughout the oil pan. There was a full handfull of the stuff in the bottom of the pan. The oil pickup screen was 1/2 blocked by RTV that had gotten on the screen when it was liquid. The oil pump had evidence in it that it had passed some RTV through it also.

A little dab will do ya!! The FSM recommends a bead size for your motor, stick to that recommendation.
