The lid has a spring. Does your lid leak? No? Move on. Yes? The rubber flat gasket under the lid, and/or the 01A-6749 lid bolt seal has failed. The bolt seal is a fiber type material and works great. Twenty years ago when you bought a new FRAM C-3P or equivalent oil filter, you also got in the kit the large rubber flat gasket that goes under the lid and the 01A-6749 bolt lid gasket -see PIX. Nowadays when you buy a new oil filter, even from CNH, you don't get that 01A-6749 bolt seal, and some don't even give you the large rubber flat gasket. Also, the FRAM C-3 (and other brands) filter don't have the little handle on the top if filter to assist easier removal when you change the filter. The good news is the lid seal/washer part is still made and sold at CNH -SEE PIX. Now some fellas may have had better luck than I using steel, copper, nylon, or plastic washers for the seal, but I never did -they always still leaked. About 16 years ago I bought a handful at my local CNH dealer and stocked up. Also good new20 years ago that first seal I bought is still on my 8N oil filter housing so they are reliable. The ESSENTIAL MANUALS and MPC's are important tools, look at the MPC's in our MANUALS forum.
