I just bought some of the silicon based oil pan gaskets from Vech and I have a quick question. Do I use any form of gasket sealer on these when Iinstall the pan?

I would never use any sealer on any oil pan gasket, OEM or not.

No sealant, but all surfaces

No sealant, but all surfaces must be clean and dry or the silicone gasket will squeeze out.

Oil Pan Sealant

I realize you already have a silicone gasket, I would use a cork gasket with Motoseal from Permatex. The sealant is grey in color and wipes off easy. More importantly than the pan gasket sealing is the bolts sealing. I use Motoseal on the bolts and gasket with excellent results. Without it, oil will weep from the bolts. And of course don't over tighten. If you use sealant, once it sets up don't tighten the bolts anymore. You will crack the sealant.

I never have used silicone

I never have used silicone gaskets on my /2 but have done so on my Ural valve covers.
Original primitive gasketing from Russia sucked and the cork ENGO ones were not any better.
Someone came of with these silicone ones and I have never had any problems with them at all. That's barring a mechanic friend of mine who over tightened and crushed one of the gaskets which came apart the next time I went to adjust the valves. Have to buy in pairs so I changed only the damaged one. On the other side of the engine I'm still using the same original silicone gasket going on 10 years now.

Here's the odd thing that I had to get over... smearing a fingerfull of oil or gasket sealer on top or under the gasket as I had always been taught. That's a big No-No. Silicone gaskets need nothing and will leak like a sieve if you do that.
Recommended good practice is to clean them and the two surfaces you are mating with alcohol prior to installation. Have to be absolutely clean for them to work properly.
Never, ever a leak of any type.

Thanks everyone, I decided to

Thanks everyone, I decided to try these gaskets from Vech because my oil pan was over tightened by the previous owner. I spent a very long time hammering it flat with a a small body hammer and a dolly that I made to fit. I plan to seal the bolts and clean everything very well.

Ha. I agree. Been told they are that color so you can better see any leaks but not sure if that is actually true.

+1 on using a cork gasket

+1 on using a cork gasket with a high quality sealant on the oil pan. I've used silicone gaskets on the valve covers with good success, but had issues with leaks using a silicone gasket on the oil pan. A decent quality cast aluminum deep sump will tend to provide a better sealing surface than the stock steel oil pan.

If you're not a stickler for originality, consider replacing the oil pan bolts with studs and nuts, using thread sealant on the studs that screw into the block. This allows for removing the oil pan by removing the nuts without disrupting the thread sealant.

now that's a good idea

Studs sound like a better idea for the sump.

Thanks for the idea.
