What do you guys use to stop drain plug seepage? My Moroso pan leaks like a sieve from the drain plugs and I can't get them to stop. It's really driving me nuts having a new motor that leaks.

Could you put a washer on the plug and make a rubber gasket?

I vote for a washer of some sort. I don't like anything with silicone near my oil where it might infiltrate the oil passages and clog an artery

Never use silicone, I use a teflon based creme on all my drain plugs. It does two things. It seals and also gives some lubrication so the drain plug comes out easier the next time around

Currently has washers and teflon tape on the plugs. Still seeps though. Front plug is a plastic washer, and the rear is a copper one. Both leak equally. I don't like using the tape, but without it, I lost like half a quart overnight, it was ridiculous.

It didn't leak a drop until after the first oil change when I had to crack them open. I think I just need to find a good set of seals. I'd rather have a factory pan on it at this point, but I just got the car back together and I really don't want to take it apart again.

I heard that they use to make gaskets out of leather, you could try hacking up an old belt and make a washer out of it putting it fuzzy side to the oil. Im sure that over time it would saturate and drip but it would be a quick fix till you could come up with something better. I wouldnt think that a new pan would leak like that.

I'm losing about 100 mils a week as of right now. It was a lot worse before, I'll try the rubber oring/washer thing and see if that helps.

Im surpised a copper crush washer doesnt work. I forget the brand but they make a oringed flanged head that seals against the pan, i'll look for it next outing to my parts guy.

You do know crush washer should be replaced every time right?

Make a washer out of gasket material from advance auto, its the grey gasket roll on the shelf. The plastic washers eventually leak and split. I had a milodon oil pan that i had to file the threaded bung flatter so the bolt tightened flusher against the oil pan.

why not just go to the auto parts store and get a rubber washer gasket in the help section for drain plugs?

Ya I would just bring your drain plugs into Napa and have them match you up with some gaskets

I've tried lots of stuff over the years, and the thing that finally stopped drips for good was pasting some ultra black silicone on the plug threads before you put it back in. Every time you change the oil, clean off the old silicone and reapply. Using this method, my car doesn't drip a single drop.

I'm not sure how that would happen, it's super common (and often specified) to use silicone on things like valve cover gaskets, intake manifold gaskets, oil pan gaskets, etc. Why not use it on drain plugs?

Yeah, I replaced them with the same type that was on it too.

Hadn't thought of this, I'll put it on the "to try" list.
