How To Replace a Rear Main Seal - Without Removing Trans or Engine!

Replacing the rear main seal in a 351c without removing the engine or transmission. yes, a lift was involved, but there engine and transmission is still in the car. this all could be done for a few hours of work. saving you lots of time!!!

"If I can do it anybody can do it", he says standing in front of his car up on a lift surrounded by a garage, tools, spare speed parts. And it's pretty obvious he's done this stuff his whole life and so has his whole family. 🙄

If I had that garage, I'd pull my engine 2-3 times a week .

Here I am, on my back, oil running down my armpits... at least my 65' Ranchero doesn't have a cross-member in the way.

Good video, but you have a Rack that allows you to do this with ease. For those that use floor jacks, limited room and using a floor jack to jack up the engine from the front crank pully is a little more intimidating. Use caution when using a floor jack on the Crank Pully. Make sure you don't run into hitting the Engine Fan into a radiator shroud or flexing the upper and lower radiator hoses where you damage these parts. If doubtful ask a professional or someone that has worked on cars. A question not asked is where we run into problems. UTUBE or Google is not always your friend. Good stuff.

Man, if I just got a new transmission and the seal was leaking, I’d be pissed. It’s cool you were able to get it without taking them apart though.

I'am Your Newest Subscriber Great Videos. I Just Got A 1999 Astro Van That Leaks Oil From The Rear Main Steal Hope This Video Helps Me

ALL ENGINES with a 2 piece seal can be done like this. THAT'S THE DIFFERENCE. All one piece seals CANNOT BE DONE without removing engine or transmission!!!

Thank you for the advice. Unlike some in the comments it's not all about the best tools it's how you use them

Nice video thanks. I have a sbc and my crank shows about the same or a little less wear than the one seen in the video. Was the crank journal wear anything to worry about? Did you have any trouble with the crank bearing not lasting?

Helpful video for those with a rear main seal problem. Also, your patience with what I assume is your kid is nothing short of saint-like! I kept waiting for you to holler "STOP IT" to your restless child banging on something for what seemed to be no reason other than to bother you while making a video and not paying attention to him. I must say, you are a better man than I.

Yep, it can be done. I’ve replaced rod bearings on all 8 rods of a 351C in a 71 Torino without pulling motor. I did the rear main seal on a 69 mustang with a 351W without pulling motor.

All half moon rear main seals need silicone or permatex for leak prevention between the two good job

Thx 🤓
I had to watch it a few times to understand because I never seen a rear seal in an engine so I didn't know where to look without being pointed at it.
I also noticed you unbolted the motormounts and raised the engine to free the oilpan.
You might wanna mention stuff like that cause I think thats a big step for folks that are attempting this for the first time, I understand it's not necessary on all cars.
Also wondering what greas to use installing the seal 🤔
All&all a usefull video, have more confidence doin this job on my 460 now.
Oh hats of to the drummer 😉

Never knew that could be done great knowledge and can do attitude 👍👍

[patrickszar]

Great video . I didn't know the rear main could be in two pieces. Just need to determine if that's true of my Chevy 305. I gotta say though, whoever was making all the racket in the background towards the end made it hard to hear what was being said without rewinding.

Wow bud really great video! I am really impressed! 👍👍 Rang your bell. Really cool car. Amber is jelóus! Keep it up you are on your way!

I would subscribe to anything Bacon. It doesn’t hurt that this dude is cool as a fan and smarter than any mechanic in my town. Sub #319

If the guy before you went crazy with RTV it can be a different story getting the old one out. Been there.

I like your video and know that your removal technique would work but I'm in a quandry over a 1956 Ford jubilee tractor engine with a rope seal. Have the bottom main cap out, that half of the rope seal removed, but wondering if you have any tricks to remove the top half of the seal. My two possibilitiees would be 1) running a screw up into the rope and hopefully pulling out (after loosening the other 2 main caps of course) or 2) finding a thick piece of relatively stiff copper wire to punch one side upwards and then grab the other side, if it comes out, with needle nose pliers like you did with the rubber seal. Let me know if you have any suggestions. Worst case scenario, what if I left the top alone and just replaced the bottom half with the rubber seal from the gasket set?

I wonder if it would be a 2 piece rear main seal on my 292 V8 🤔
