There is a small oil leak at the rear oil pan seal. I've drained the oil, let it dry a couple days and cleaned the area well. I would like to try to stop the leak without removing the pan. Has anyone had success with a particular brand/type sealer applied externally for this purpose?

Re: '66 BIG BLOCK OIL PAN LEAK
I personally have never hear of it.
But from my personal perspective
JUST SAY NO TO OIL LEAKS
I hate them and will not have them on any of my cars.I had a oil leak I think last year from the rear of the pan.I dropped the pan.(not that hard I think the hardest part was removing the steering link)One of my service manuals gave a very detail description of how to do it including starting with raising the car up on jacks.I also go advice from this board.I also replaced my rear main seal witch is where my leak was coming from. That was the only scarry part making sure I was installing the seal the right was for some reason when I had the new seal in my hand it was slightly different from the one that was in the motor and the description from the instruction that came with the seal was different from the manual I was useing.So I posted a picture of it and asked what side should face the engine and then It was very simple to install.The one that came out was hard and brittle.
Also From personal exspereance I have found that any time I try and put a bandaid on something (spray on magic sealer) I am just wasting my time and effort.Just dig in and do it correctly youll save your self alot of headaches in the future.(This recomendation is not trying to offend you in any way)It just I have been playing with cars forever and personally I have found out I am ALWAYS better off comitting to doing the correct repair the first time rather then having to visit it again because the bandaid has failed.
Case in point I have a post about a TI distributor on this board.And real breifly while I was making a trade with a fellow for a TI distributor for some take off parts from my car I was thinking just to reinstall the distributor that was in a box with a portion of a burnt up TI wiring harness and cross my fingure it didnt burn up again.In stead I decided I WILL send my distributor and module to dave to have it rebuilt prior to installing it.(There must be a reason the harness was burnt up as it was)When I purchase my car I had electrical bugs all over the place and what I had found was that the fellow had extra grounds connected all over the place.everthing had a jumper ground conned to it.He actually had a heavey ground wire connecteing practilly everthing back to the battery then to the frame.Anyways I folllowed the wiring diagram and removed every thing that was not on my factory wiring diagram.I found that the power source for the wiper and heater was actuall sent to a ground instead of power.And since that Day I have never had an electrical problem in my car.So allthough it would be easey for me to assume the harness was burnt because some owner before me could have grounded a power source for the harness I will not take the chance of ruining something else.
I could probably give you 100 instances in less then 30 secounds of short cut I have taken in the past.But now I am a little wiser (still as cheap as I always was)and dont waste my time and effort on short cuts I just commit to investing my time and money doing it correctly the first timeComment
