Preferred Oil Pan Gasket

[SHELB66]

Is there a preferred oil pan gasket for the '66 Shelby?  I'll be having some work done on my Hertz and may need to source a part or two.  Any recommendations would be greatly appreciated!

I asked this question a few years ago and was told the following gasket was highly recommended. FelPro part number OS1326OT I used it on my oil pan and it worked great and I've never had a leak in the last 5-6 years.

I still like cork oil pan and valve cover gaskets. I glue them to the pan or VC then put a light film of grease on the exposed side. That makes it so it won't stick to the block or head and you can adj the valves (or check the bearings) without destroying the gasket.

It depends if you are concerned about the original look or not. The blue color of the Fel Pro OS1326OT oil pan gasket screams aftermarket but is a good modern replacement. Where as a cork gasket blends into that assemblyline vib.

Totally agree.  The reason I used the Felpro was I had issues with the cork gasket that was on it.  I am also not planning to have the car judge so functionality was more important than looks to me.

Thanks everyone!  Since functionality is the key for me I'll probably go with the FelPro.  My car is "leak city" as I'm faced with a stripped oil pan plug hole, leaking rear main seal, and leaky trans due to what I believe to be a bad shifter shaft seal.  It should all be taken care of within a couple of months.  Turns out this will be the perfect time to get my correct HiPo trans finally installed in my car.  I came across a freshly rebuilt trans several years ago that actually came out of a '66 Hertz!

brand, definitely FELPRO that would be my choice

which one would I use ?

Depends on how CONCURIOUS you are


Me, I would go with their blue oil pan gasket

But if in a "judged" event, once they look at your oil pan, the monkey poo will get flung and it's back to your zoo cell, no bananas for you

The cork gasket is the original type used and will last a good long time

wishing you the very best with what ever decision you decide to go with

have a great day, laters !

What a great find!  Like finding Inca gold when various rare pieces are found.
