Slow oil drip from oil pan drain plug

[hpg4815]

Hi, I reused the original oil pan for my 440 RB block when I built it, looked like it was in good shape as it only had a couple light dins in it. After getting the engine installed and running, I see there is a small drip from the oil pan drain nut. I bought a new one that had a nylon washer that came with it. I feel like it slowed it down more, but the leak is still present. any suggestions on how to stop the leak?

THanks

How about a small swear of RTV on the bolt threads? Or the felpro gray bolt gasket

Don't put sealer on the bolt threads. You will hate it. Try different type of sealing washers, like a copper or aluminum, and tighten it up.

The oil plug is straight threads, not meant for sealing, that's what the washer is for. If you put anything on the threads count on it ending up inside the engine.

It could have a crack around the pan hole

Next time you change the oil take a fine file and lightly draw it across the sealing surface of the pan to insure there's not a burr there. I like the copper washers from NAPA.
Good luck to you...

I just changed my oil and bought a nylon washer, that was dumb, not only did it leak but the washer I removed was metal with the rubber insert.

I bought another metal/rubber washer, put some gray gear oil rtv, in the green tube, on the washer, pulled the plug, stuck my finger in the hole, put the washer on, and put it back in the pan as the oil dripped out.

Hasn't leaked a drop.
