Oil Drain Plug Gasket Suggestion
I changed the oil on my Roush 402 and installed a new copper washer on the oil drain plug. After test driving it (test drove, cleaned the area thoroughly, and test drove the car again) I noticed some seepage around the drain plug.
It's not even enough to drip on the floor and I know it's not coming from another source. The drain plug can't be tightened any more. Anyone have any suggestions for another type of gasket (rubber?) or a gasket to use in conjunction with the copper ring? Maybe a little dab of high temp RTV? |
Sometimes that seepage stops by itself after a couple of heat cycles, so don't rush. If it continues to seep, I've had luck with Dorman's rubber/steel combo. Available from Summit.

Thanks Patrick. I'll put some miles on the car and see if it stops by itself.

Doug - guess what...mine does the same. Only when I really inspected it looks like the drip is actually coming from the threaded fitting plug (some us it for the oil temp gauge) and wisking back a few inches. Never actually forms a drip so i am not touching it. This fitting is on the pan a few inches forward of the oil drain plug on the drivers side.

work it a couple times back and forth to get the parts to wear together then put the final torque on it and see if it holds. soft aluminum washers work also.
|
I use a thick rubber gasket from NAPA. No seepage at all.
|
i had the same issues with my canton pan drain plug, no matter what gasket i used it seeped. i wrapped the threads with teflon tape problem over. it takes a minute extra but it never leaks.
|
I installed a permanent quick release fitting. I never have to remove the drain plug. I simply remove the protective cover and snap on a drain hose.

Anyone know what size the drain plug is on Roush 402? I just changed the oil and don't want waste it measuring the plug. |
Just the rubber gasket all by itself. I don't use any thread sealer, either.

This is the quick release system from Aeroquip. Roscoe |
smear a little Hylomar on the threads. That fixed my seepage. It never dries out so removal is easy.
you can get the Hylomar Universal Blue Racing Formula easily in the USA thru the Permatex brand number # 85249 http://www.hylomarsealant.com/_resou.../products.html http://www.hylomarsealant.com/index....ckingid=672074 Z. |
GM uses a Aluminum washer 1/2" with a rubber insert. Available at any GM dealer, maybe NAPA too? Ford uses something similar on there vehicles with aluminum oil pans.

Thanks for all of the suggestions. I went down to the Napa store this morning and the parts guy brought out a drawer with a bunch of different types of oil plug gaskets. They had the Dormand, but the diameter of the copper ring was too large to be effective.
I ended up finding a rubber gasket (Napa PN 704-1964) that fits tightly around the oil plug with a perfect diameter to accommodate the copper ring and the pan surface. I put the rubber gasket on first, then the copper ring, the the oil plug. Seems to be working so far. |
