oil filter housing leak

[akguy09]

When I bought my Cub I changed out the nasty old oil and put in a new filter. Since that day I get oil seepage around the bolt and copper washer and I don't want to keep tightening it. I will assume that a new copper washer may help? Or if anyone has any other advice.

Thanks

Hardware store for new copper washer or autoparts store for drain plug washer with rubberized gasket.

Marc if the new copper washer does not cure the oil seepage you may need a new lid for the canister. Some were made of aluminum or cheap pot metal and would crush the more you tightened the more it would leak. Found a used at TM and it solved my problem on my 1950 Cub.

thanks, I am going to try a new copper washer and I'll loosen it some since tightening it did not help.

Also, make sure there are no scratches in, or debris on, both mating surfaces, the lid and the underside of the bolt head. Perhaps use some fine emery paper to polish the surfaces.

As Dale said clean the bolt and top of cover surface, I use a rubber washer on top of the copper washer .

Hi,
IH changed to a steel oil filter cover in the early 1950's.
If the soft metal oil filter cover is bent down, or broken, TM Tractor sells the newer style cover.
You can look at the pics.

Sometimes I have needed to use a thin coat of sealer on the copper washer to get it to seal.
Clean off all oil first, wash the bolt head area, cover, and washer with solvent, and dry them before putting on the sealer.

As mentioned above, if you have the early style pot metal cover, replace it with a steel one. The pot metal cover yields it's flat shape, over time and will become very difficult to get sealed up. Used steel covers are readily available.

This weekend I opened up the oil filter housing and cleaned the paint on the bolt head, then lightly sanded the cover, and took off the 2nd copper washer.
Now there is now more leak. The one copper washer was mangled and stuck to the head of the bolt, I'll assume no one caught that before, I sure didn't when i changed the oil about a month ago. Anyway with 1 copper washer and a clean cover and bolt I have no more leak. thanks for everyone's input.
