Gasket question
When replacing a worn gasket, what is the proper way of doing so?
For instance i'm going to be replacing a leaky oil pan. I have the gasket but it is a 4 part seal, which has me concerned that it may leak after i install it.
Is there any seal material like a paste or gel i can also apply to ensure a good seal?
Any thoughts would be appreciated.

Make sure the gasket surface is as clean as can be spray it off with carb cleaner(watch your bearings!!) For oil pan gaskets I use the black RTV silicone put a good layer on the pan, a good layer on the engine, let it sit for a bit and then bolt her up make sure you torque in sequence and to the proper spec and you should be aokay!!

Another Option/Upgrade
Sometime in the late 80's/early 90's, Ford went to a 1 piece noeprene oilpan gasket for the I-6. The new gasket sealed much better and was easier to install. The problem is that the oilpan is also different. The old oilpan had each mounting bolt hole dimpled to act as a torque stop to prevent the old cork gasket from beaing crushed. The new oilpan mounting surface is completely flat and the neoprene gasket has metal spacers molded into it to act as the torque stop. You can either get a newer oilpan from a wrecking yard, or pound down the dimples in your current pan and redrill the holes to the correct size. Both options will then allow you to use the new 1 piece neoprene gasket.
I chose the second option and it worked flawless on my 300 I-6.

Hey Etachell, I stopped by my local auto parts store and asked about the neoprene gasket for the 300, they had one in stock and let me look at it. Pretty nice looking part, like you said one complete piece, with metal stops built right in. The only thing different was that it is not neoprene but instead it is silicone. Just as good i hope.
Anyway, eventually i'll take down the pan and probably grind down the dimples. I do have one question to all.
If i have a silicone gasket will adding RTV sealant help or is it a waste?
I'm not sure how it will stick to silicone.
Anyway thanks again.

It will work just fine. I put my gasket on dry and haven't had a hint of a leak. Done this on a couple sixes now. I fount is was better to pound the dimples flat with a drift while the underside of the pan lip was supported solidly. This will cause the bolt holes to shrink a bit due to the extra metal. You can then go around the holes and drill them back out to the correct size. I would then chuck up a wire cup brush in the cordless drill and clean up the burrs from drilling.
