New to forum and have read previous posts about stripped drain plug threads and whether or not to use crush washers to prevent stripping (I've always used them). My problem is my drain threads are already stripped, likely due to over tightening by garages in the past.

Now the drain plug will not tighten completely with the washer--it gets to a certain tightness, then loosens, then tightens, etc. But if I don't use the washer, the drain plug will tighten all the way. So my question is since the threads are already stripped, is it okay to go ahead and use the plug without the washer? I realize the long term fix is to replace the pan. Currently, the drain plug with washer (as tight as i can get it) has a slow drip and I can't imagine it would be any worse without the washer. Thanks.

 

Welcome!

What about a thinner washer especially one made of some softer material?

Also consider a HeliCoil or TimeSert to repair the threads. A new pan is $$$ so try some alternatives first.

This is realy just a welcome/intro place, so I'm gonna move this over to General Tech.

 

Go to your local AutoZone and have them show you the tool to rent or buy to fix that problem..they most always have them in stock..

The softer material washer may work like JimBlake suggested. For example, Toyota has used a softer drain plug washer/gasket; I usually have to use a flat-head screwdriver to pop off the washer/gasket from the drain pan after the plug is removed, as the washer/gasket seems to mold around the drain pan hole.

 

Thanks. So I assume installing the plug without any washer will be as bad or worse than the slight drip with washer? Could I use a nylon washer as a substitute for the crush washer you suggested?

 

If you can find it, I would try a gasket made out of fiber or synthetic material, as the Toyota OEM washer/gasket with the fiber or synthetic material kind of formed into the shape of the oil pan drain opening.

This Dorman washer/gasket inner diameter is just slightly smaller than the Honda one and may still fit fine.
