cork oil pan gasket

A gasket is the correct way to do it but when I built my BA I did not use any new gaskets and if I needed one I used silicone form a gasket. Those gaskets where the valve cover and the oil pan that U sued the form a gasket on and that was 3 years ago if not more
 
You use the cork gskt. and IF you MUST put something on it then use either copper coat or Permatex . NOT SILLYCONIE . As i have seen more then one engine go south because some IDIOT used guppy goo and it ozzed out on the inside of the oil pan and fell off and plugged the pick up screen and guess what the engine lost oil pressure oh my wonder how that happened . I have spent hours on Hyd. systems that some wizz kid used the stuff on Hyd systems . It has it's place and engine and hyd. systems are not one of them.
 
My preference is always to use gaskets when appropriate. If the mating surfaces are CLEAN and not distorted, the gasket is the only way to go.

Now, if there is pitting, distortion, or some other imperfection in the mating surfaces, then a sealer of some type is in order. There are 3 things I use, and all are dependent upon what area/application it is being used on. I use Permatex #2, Aviation gasket sealer, and silicone. The only time I use silicone on an engine is for water jacket or related applications. Anything where fuel or oil is present, I use the permatex or aviation sealers.

Hope this helps, and as always: IMHO, your mileage may vary.
 
I am backing up the below statement. DO NOT use silicone on a cork gasket ever! It will "ooze" out and get into places it DOES NOT belong.Also,It will tend to break the gasket apart.(My transmission buddy knows this TOO WELL!)


My way of doing it: Make sure your oil pan rail is straight.if it is NOT,then either make it that way,or get another pan.(Be sure to get the bolt "dimpling" out of the pan bolt holes. A little work with a ball pien hammer, flat punch on a flat surface works good here.)

Take a SMALL amout/little dabs of something like 3M weather strip adhesive or Permatex "Hi Tack" and glue the gasket to the oil pan's rail,then oil the block surface where the gasket is sealing to the pan.Tighten the pan down evenly and DO NOT over tighten the pan bolts!!!!!

The ONLY time I ever use silicone on an oil pan is like on a BB Chev pan where the cork rail gaskets meet the rubber end gaskets. ONLY in the corners.;)

Was that "long winded" enough???? lol
 
Where do you find a cork oil pan gasket!?! My MD gasket a couple winters ago was synthetic right from the dealer.
 
Cork or synthetic, either works and works fine. Depends upon the mfg'r and kit you buy. I have seen both.

The point I was trying to make doesn't preference cork vs. synthetic. Also, the point around DO NOT over-tighten is spot on. You want a very small amount of "crush" to seal.......over doing it is very very counterproductive.
 
Silicone works fine a long you use it sparingly and let it dry. There should never be enough of any sealer to ooze out and if you don"t have time to let it dry completely don"t use it at all.

I agree that overtightening is the main source of trouble with sheet-metal pans (and with similar valve covers). It"s also a good idea to tighten the bolts in a pattern similar to that for a head.

That's what the HF 3/8" torque wrench is for. I torque just about every bolt on my tractor.
 
I glue the gasket to one of the surfaces with hitack and put a dab of sealant in the corners where things meet up.

Clean all surfaces with brake clean or lacquer thinner.
 
Just the opposite--Comes with the kits I buy--I don't think I have seen a synthetic one. Have not bought an oil pan one from the dealer for several years -- they were cork then.

My MD gasket was bad. It came folded in half around a toilet paper tube and was pretty thin. It was tough to get it straight on the pan. I just used grease to stick it down. No magic potion.
