How to Replace the Rear Main Seal in a Ford 289 or 302
Рет қаралды 28,820
2 жыл бұрынWhat happens when you go to replace the rear main seal on your Ford 289 or 302 and you find out it's the original Rope Seal?
First, you panic a little. Then, you realize this is doable and you move forward.
Using either a Sneaky Pete or a long wood screw, thread it up inside the old seal and pull it out. You may need to use some leverage, like using a hammer and a piece of wood and pry out the screw. It may sound bad but it works, trust me. :)

@@AndyKruseChannel Well for the one in the timing cover, I would probably just build some tac welds on it to the point of being able to grab onto it with a stud remover. Those timing coves are aluminum so your welds will only stick to the broken part of the bolt. As far as the broken ones in the frame rail....well that might also involve my welder and maybe a cutoff wheel. I've never actually broken one of those off (yet). I usually try my best to anticipate these things working on these every day. So I typically try to focus on the feel of the bolts as I remove them and if they feel like they are going to cause a fight, out comes the wd-40 and my propane torch. I'll be watching for that repair video when it comes out.

I did it, mine wasn’t easy. It took me three attempts. The first try the top seal wouldn’t budge and I had to put everything back together. Every time I tried on my vehicle the crossmember must be removed to remove the oil pan and the engine has to be supported. It’s a little dangerous and I’m alone. The second attempt I hit it harder with a punch and screwdriver…nothing seemed to be able to break it free. The third and final try actually worked. I used a cut off handle from a milk sampling cup handle from a dairy because it was stainless steel and the correct diameter. I am so happy it worked. Whoever built this engine did not overlap the seals and it was probably stuck from several overheating since 1964. Thank you for motivating me so that I got it done 👍🏼👏👏👏👏

@brandongeddes1008 Жыл бұрын
I tore into mine yesterday after watching your videos and reading the forums. Less than 2 hours to take it apart, at least 3 hours to get the upper half of the old rope seal out. It was indeed essential to spin the crank while pulling on a screw t threaded into the seal. I didn’t lube the new upper seal enough and shaved some of the rubber off the backside. It probably would have been fine, but bought a new one and dipped it in STP and filed the sharp edge of the block a little. It slid in smoothly. Another 5 or 6 hours to reassemble but that included cleaning and painting the oil pan. The oil pan has been double gasket-ed at both ends, so I’m curious to see if that warped it enough to cause an issue. Thanks for the great video!

Well here I am again. I'm really uncomfortable with the oil pressure that I'm running. The 84 in a cold start and 40 at warm idol is fine. But the 10 psi for every thousand RPM I am doubling. Need to pull the oil pan and see what pump I have. You made disconnecting the idler arm look a lot easier than it was. I had to use a 4 lb 18 inch handle sledge hammer to drive it down like you showed in the video. Hopefully when I pull the Canton 9 quart oil pan there is a crazy high pressure pump in there and I can replace it with a high-volume or just standard pump.

@@AndyKruseChannel Honestly I'm assuming that the Canton 9 quart oil pan is running a Melling HV pump because that is the pump that is recommended for the Canton pickup that is used with this pan. I will consider a standard volume pump a upgrade as long as it gets me to 10 lb of pressure for every thousand RPM and 30 at hot idle. The current issue is all the bolts are out of the oil pan and it will not come loose at all. I'm going to try a heat gun because I would hate to bend a 460$ oil pan because it was silicone welded

I have used VMF for a lot of research and info. I believe the one-piece seal started in 1983 (or around there) so if your block is from '91, you're correct about it being a one-piece. Unfortunately, you'll need to pull the Trans to get after that seal.

@AndyKruseChannel 2 жыл бұрын
Summit Racing had a sale on this pan (generic pan, no-name), so I purchased it over the Scott Drake pan I used on my previous '66. That was a mistake. The indentation on the saddle of the front of the pan wasn't in the right place and it caused oil to leak out the front. At first I thought I had done something wrong with the install, but I later found out it was the pan. I have since gone back and replaced the oil pan with the same pan (same model number) I had on my previous '66. I didn't bother to make a video because I wasn't sure about everything until later down the road when the new pan was not leaking. So, I'm glad that my procedures are still good for doing the work, but I didn't have all the info until several weeks later when I noticed the new pan was doing the job. You'll notice a blue oil pan on later videos and not that black one from this video. :)

Hey man doing teh same job, my bearing on the main cap looks copper with minor scar marks on it like yours, would you say its concerning? I know the engine may need rebuilt soon but im wondering how concerned I should be. It looks almost identical to yours. If the engine isnt making noise yet, do I atleast have some time?
@AndyKruseChannel 10 ай бұрын
My engine wasn't making any noise to indicate the bearing were on their way out. But once I looked at them, I knew I was on borrowed time. At the time I made this video, I knew that I would be getting a built engine down the road, so I chose to roll the dice. My engine lasted until I was able to pull it for the new one. But, I also chose to take it easy on this engine just so it would last until the new one was ready. Maybe I got lucky, maybe I had another 15k miles before it would have been an issue. In your case, you've got the indicators that your bearings are on their way out. The easy you are on the engine, the longer you can go until you replace those bearings. However, the longer you go, to higher the risk you can damage the rest of the engine. Low oil pressure will be one of the first indicators that she's about done. My oil pressure was in the teens and sometimes single digits, so that was a bigger "heads up" my engine was about done. Good luck! :)
