Topic: Oil Pan Sealer [oil-resistant]

[Kingchief]

Hello,

What brand or type of oil-resistant sealer would be applicable when installing an oil pan?  My car is an early GT-350 with the Cobra oil pan.  It does not leak now so I just want to remove it, clean it and reinstall.  Not urgent but would like to have some ideas.

Thanks again,

You'll probably get several different sealers or methods, here's mine. First of all I am a line tech with 30 years experience and have taken off hundreds of oil pans.  RTV is way over-used. Assuming the motor is in the car. I would use spray contact cement on the block side of the gasket to hold it and limited use of RTV in the corners and over the top of the end rubber pieces. Install the pan and lightly tighten the bolts. Let the RTV dry overnight and finish tightening the next day.
 Fle-pro makes a nice 1 piece gasket.# OS13260T if your not striving for originality.

You can use Aircraft Form-A-Gasket as a sealant but it may be visible on the finished product some where depending on how much you use and where you apply it to the gasket and or pan. Once on clean up (if you later replace the gasket) is not easy since this stuff is tough but that is what you wanted in the first place.

Here is some advice. I have an FE with the T-sump aluminum pan. DO NOT use the cork imprebnated with rubber!  Use the ultra gray sealer on BOTH sides of the gasket. When the product cures you can literally peel the sealer that squeezes out. Do NOT touch it until it cures. if you wipe it or smeal the bead that squeezes out it will not pull off.
No one will see the sealer that way. Be careful about over-tightening as well. Make sure the sufraces are completely free of oil.

Remember. if your going for the original look, the gaskets were black on the top and bottom surfaces while uncoated (natural) cork on the outer edges

Thank you everyone.  The car does currently have black goop on the top and bottom surfaces with the natural cork.  Working good.  I am going to experiment on my '57 T-bird first.  It currently leaks like CRAZY!

Thanks again.
