NO OIL LEAKS! Rear Main Seal & Oil Pan Gasket (First Gen Dodge Ram, Ramcharger)

[@Yellow12Valve]

Great job! , I have had just done this job last summer with my 91 dodge, but mine had the cummins in it so I was alot more challenging cause i had to remove the transmisson and there were alot more oil pan bolts😅

[@C_71]

I have a 1978 D150 that I bought last October...I drove it from a neighboring state and it died when I got home. Fathers Day i got it running again and have been driving it every since, but I replaced everything on the top end minus heads, an aluminum radiator and all the elected leaders electrical ignition parts. I intend to do the suspension, I have headers for it, but over the winter I want to tear the motor apart and install the goodies with the stock bottom end just freshened up. This is a job I'm tackling this week after installing motor mounts and still need to install the transmission mount which up do after this is done! Great videos and information!

[@theTHiiiNG]

Even if I don't do this exact repair, these videos definitely inspire me to do all the jobs I've been putting off for months. Keep those videos coming!

Brother I just bought a 1988 Dodge Ram D100 literally 6 days ago and I already watched all your old dodge videos, it's really awesome the way you explain everything and make sure all the information is correct, honestly you make it look easy lol, I just wanted to say that this is one of the coolest KZbin channels I've seen and that truck of yours is badass bro. Keep the videos of the old dodge coming, I'll stay tuned. \m/

Thank you for making this. I just completed the rear main seal on my 75 dodge dart, and this was VERY helpful.

[@JasonExplainsThings]

Awesome!

[@trevorshiffermiller2412]

This is a great video. I have a 96 Dodge Ram (2nd gen) with the 360 (5.9) that also has a leak from the rear main seal. There are a couple of small differences that I know about but this is a fantastic walk threw on how to do this job. I am also, like you, replacing the oil pump while I am in there. I have a few more miles (175k) and figure it is just wise while I am in there. Just Thank you for a great video!

Good job again! Love the Dodge truck vids since I have a 1975 D100 with a slant 6 myself. Fixing to redo my valve cover gasket along with the front wheel bearings. Your trial and error hiccups mean you are human and demonstrates the same little things the rest of us will temporarily mess up and fix along the way on these DIY repairs :-) Keep the Dodge truck maintenance vids coming!

[@alexmitchell7083]

If you’re willing to use the silicone pan gasket, felpro typically includes the plastic pins that will not only align the pan but hold it in place so you can install all other bolts. Super convenient and easier than having to make your own. Great video friend. Keep em coming!

[@psychosocial6112]

86 D250 here. 👋 Watched a couple of your Ram videos and just subscribed to the channel. I like the way you break your content down and the quirkiness of your personality. Very helpful information and I hope to see some more content on the D150. Maybe I'll get to my oil leak too here soon like. And maybe a full exhaust system is in the making for you here soonish. 😉 GIVE IT THE BEANS!!

[@JasonExplainsThings]

My exhaust is in good shape! :-) But thanks! Yes, more Dodge content will come for sure.

[@jwbroyles1]

Great job, about to buy the same truck with a bad rear main. Pretty sure I can handle this. Very appreciative of your efforts

[@brettrossi4117]

I've been avoiding this, because thought you needed to remove trans for my 86, but it looks like its a lot like my XJ. Makes it doable!

[@JasonExplainsThings]

Yeah, I thought raising the engine would require an engine hoist. Not too bad of a job at all.

[@peppylapeeeU]

I put a new Radiator and electric fan on my 89 D250 and after I was done and fired it up a growing pool of oil was under it as I looked for Radiator leaks. I heard it could be done without engine removal but got stuck at getting it out. Did some looking and saw where the engine mounts could be loosened so when I get back at it I'll hopefully get it wrapped up. Glad you replaced the pump as they're cheap and good insurance. In case anybody is curious never use a highflo pump as it will starve the crank.

[@PTucker0864]

Good job. With that many miles, I might've replaced all of the rod bearings while it was open. But also, I might've had the cylinder heads off too, then pushed all of the piston/rods out, used a deglazing hone on the cylinders, then replaced all of the piston rings.....I might have to do that while the heads are off right now....my 318's #4 cylinder was lower compression than the rest, and a wet test shot it waaaay up! 😆

[@QuackSuperStar]

[@liambeckemeyer2499]

So I recently did this on my 78 D150...I found that on the 318 you don't have to raise the engine at all to get the oil pan out. I'm not sure if it's simply a difference in engine size or a difference between the 70s and 80s. Either way it made it a lot easier for me.

[@JasonExplainsThings]

That’s awesome. Yeah the manual said some do some don’t. Mine definitely did. Even with raising it things were pretty tight.

[@noahingram8052]

I'm going to be using this video to fix my 318 up with some new parts thanks so much

[@matsgranqvist9928]

Did this same job on a '68 Fury with a 318 last summer. Had no leaks or nothing, it all started with pulling the threads out of the block on one of the timing cover studs and it just started snowballing from there😂

[@PentastarGarage]

I just wanted to say Jason, the one thing I learned being at dodge dealers is the best torque sequence is in a spiral. Go from the middle and just go out. And of course do a double take over all the bolts you torqued.

[@TLDLTD]

Awesome video, thank you. I am about to do this to my ‘84 Dodge and it is intimidating just looking at the shop manual. Appreciate you!!

[@JasonExplainsThings]

Thanks so much! Yes it looks very intimidating. I delayed doing this for over a year because I was scared I would mess it up. Like many things in life, everything was achievable by doing research and taking my time once I started. What’s not in the video are numerous times I stopped and triple checked stuff because I was nervous of screwing it up.

[@TLDLTD]

@@JasonExplainsThings yes I hear that for sure. Mine has a stuck oil pressure relief valve that caused the rear seal to leak. Going to change oil pump and rear seal and then re-gasket. Beautiful truck btw.

Nice truck bro

[@thomasgall5967]

Thanks so much for this video, I have watched probably 15 times now prepping to do the rear main in my LA 318. Every rear main I’ve see. Has little wings to the side as opposed to just being circular, did you see options for wings vs circular as well?

[@citysurvival3257]

I have a 1990 ramcharger 318 will this be the same process

[@ChrisTheBmxGuy]

Recently had my 3.9l out of my dakota (same design, its a 318 with 2 cylinders cut off) one tip is to put rtv in the area where the timing cover, oil pan, and block come together. Mine started leaking there. Its not bad but I only notice it because the engine is orange 🤦‍♂️

[@budlanctot3060]

To prime the oil pump before reassembly I use Vaseline to pack between the rotors so it won't lose prime when the oil drips back out of it over time before restart.

[@timmyneeley3913]

Thank you. That was a very good video.

[@douglasdailey5998]

The newer one piece oil pan gasket fits the older 80's and 70's oil pan and block, which seal a lot better and last a lot longer.

[@valentinoreyes6641]

What would be symptoms that you need to replace that? Mine leaks coolant right there in that area. Is there supposed to be coolant there?

[@JasonExplainsThings]

It would be oil not coolant if there’s a rear main seal leak.

[@judyloper422]

Rob here... I've made dozens of inquiries about door swapping. Will the door hardware from an 84 fit in an 85 door shell. I think dodge doors are the same from 81 to 89 but not sure. Some help figuring that out would be greatly appreciated on finishing my w350 project.

[@JasonExplainsThings]

I believe it is the same, but I'm not 100% sure.

Eventually I'm gonna need to do this on my 79 W150, same engine. Seems about the same as my 97 Grand Cherokee.

[@rodneycorrigan1877]

Did you use black RTV to put in the new rear main seal

[@JasonExplainsThings]

It’s shown in the video. From what I remember I put some black RTV in the spots notes in the manual.

[@AllenSullivan-o2r]

do you know of anyone doing these kinds of things to a big block dodge of the same era? I have a 1978 440 W200 and for the life of me i can't find anyone fixing big block trucks.

[@fourdoormuscle]

Did you only prime the pump while off the engine? I've seen folks priming via pump drive and not sure what's the difference

[@JasonExplainsThings]

I just followed the procedure in the shop manual.

[@thordawgzbackyard1379]

I have all the same pieces the exact same gaskets I even paused video to see if the numbers on the gasket match, n they do, so mine's an 89ramcharger 4x4 5.9 basically same type of engine anyway I have the book also, how long did it actually take, n how hard was it, I'm lil intimidated too!!! N I do most of work on my truck myself but i dont have a shop ill be in a parkinglot

[@JasonExplainsThings]

Hard to say. This took over 3 days to film and do... but creating a video makes everything take 2-3 times as long. At least a full day of work. It can be done outside, but make sure you have all the tools.

[@GregOrloski]

Great video Jason!, Quick question - Depending who you talk to there is a recommendation to add RTV to both sides of the rear main seal on the bearing end cap. Per the manual, this is only applicable to newer trucks

[@JasonExplainsThings]

I can tell you that I did add the RTV in those spots.

[@cassandrahatfield4765]

Love love love it thank you so much for this content

You asked nicely so here you go! Now take this with a grain of salt. The tube was pretty hard to measure. Lots of stuff in the way. The exterior part of the dipstick tube I could measure was roughly 14" and the dipstick itself was 33 1/4" (The part going down the tube). I'd google this stuff to confirm.
