On my 1988 F150 replacing the oil pan gasket is a nightmare of a job. Loosen motor mounts and transmission mounts. Remove upper intake manifold. Jack up engine. Drop pan a few inches and then reach in and remove oil pump and pickup tube. Then work the pan out between the bottom of the engine and the support beam. Sure wish I had known that the rear seal could be replaced without removing the transmission.
Thank you. I painted it about 10 years ago with John Deere blitz black. It's been pretty good paint for the money and I plan to repaint it later this year with the same stuff.
Did you lubricate seal with oil or something else? I’m having a hell of a time trying to push mine around the top. By the time I get to halfway it won’t move a millimeter no matter how much force I use
On some blocks there is a pin that kept the rope seal in place. If that pin is still there you will not be able to slide the seal around. I’ve read where some people cut the new seal in half and put sealer on the two ends. I’ve never tried this method so I don’t know if it works. Good luck.
Just bought a F100 with a 351w that’s got a leak somewhere back there. I assume it’s the same seal you just did this video will be helpful! How did the base pan gasket work out?
It's a much better option than the 4 piece gasket. If I were going to do it over I would still put a dab of RTV in the corners just to make sure. So far mine hasn't leaked a drop but old pan rails might not seal in the corners. Good luck!
Offsetting the seal is a myth. Those seals were made to compress towards each other, one half full in the cap, the other half fully in the block. Watch uncle tony’s garage and his 383 engine build. he goes over this in much more detail
@@jameswalker5143 those seals have to be offset. Set aside what anyone is trying to tell you, and just think about the basic logic of it on your own… you’ll find the answer. Or I can just give you the shortcut, but please think about it from a logical stand point… those seals need to be offset.
Going to do this on my 351 next month. Thanks for taking the time to upload this. Very helpful

Great video, nice truck! What color or type of paint did you paint it? I know it’s black but like what brand or paint code?
Thank you.

Did you have to lift the engine or drop the tranny?
No but I have more room than a stock truck with the QA1 front suspension.
You should of showed us, you doing the replacement. 😭😭. Good grief
That part starts at 4:40 thanks for watching.
You didn’t offset the seal
Check the seal at 10:40. Is down 3/8th or so from flush on the right side. It doesn’t need much.
