Will one of these seals work on my 2000 3.8L V6 with 5-speed manual transmission? Having a very hard time finding one anywhere.


  • The Ford Performance Rear Main Seal (83-95 5.0L) will not work with your 2000 V6. This seal will only work for the 83-95 5.0L mustangs.

    Easy and effective

    Had the clutch apart and decided to do the rear main while I was in there. Fixed my leak so well, I ordered a front seal and did it later. No more oil leaks! Great product.

    Perfect fit!

    This part was extremely easy to install on my 5.0 block. Pro tip- Use a flat head screwdriver at the 2-3 o'clock position on the outer diameter of the seal to pry it out. Slide the old ring off and save it. Use oil to lightly lube the new ring and slide it on as far as you can by hand. Put the old one over the top and use that to tap the new one in until it is full seated

    No problems

    Holds the oil inside the rear of the engine like a real main seal should do. I had to replace this on both my 94 GT and the 94 Cobra, both work normally.

    Good Product at a fair price

    I purchased this as part of a larger project to replace my clutch. My old seal was leaking, so I needed to replace it. This part fit really well, was easy to install, and solved the leaking problem.

    Rear main seal

    I had a very slow dripping leak between the bell housing and block....when I did my clutch I found it was the rear main seal, easy install and can't go wrong with a ford product on a ford car.
