- What's cooler than an old truck with no oil leaks?! NOTHING! Today we're replacing the rear main seal, oil pan gasket and oil pump on a First Gen Dodge Ram or Ramcharger. My truck is a 1987 D150 with the 360 5.9L V8, but the 318 5.2L V8 is very similar.

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😅
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!
My whole concern was I had to drop the whole trans thank goodness you made this video. I got a 1982 Power Ram W350.
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!
I have an 85 D150 with the 5.9L and these videos have helped me understand the jobs I need to tackle. Thank you for all your work.
I've got a 1985 Dodge D250 (3/4 ton) Custom with the same engine, this is super helpful because it leaks a ton of oil. One of my many things to do on that truck. Keep up the good work, I really enjoy your channel!
I have a 73 d100 with a 360 and these videos have been some of the biggest help in restoring it
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 TH-cam 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/
Dude I’m so glad you posted this. I’ve got a 79 318 with a toasted rear main, so I’m going to just replace all of this like you did so I know it’s all new and fresh when I’m done. Subscribed!
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!
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!
Great timing, about to do this on my 1986 Dodge Ram W150 !!
Good job on posting this, rebuilding my 383 for the charger putting all new gaskets and seals was cool to learn 😎
I’m very surprised that you didn’t paint the oil pan. Great job. :)
Yeah, not a bad idea with high temp paint.
Thank you for making this. I just completed the rear main seal on my 75 dodge dart, and this was VERY helpful.
Awesome!
Thank you for posting this video. I’m planning to install a rubber Maladon gasket on my 79 Power Wagon with a 360 engine. Please keep the Dodge videos comin!
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!
My dad gave me his 85 dodge b4 leaving this earth. Now with ur help slowly 🐌, but surely. It will be running like new. Felipe from Houston.
Great video... As always. Keep up the good work!
Once again a brilliant video! Such a fun channel to watch, thank you. 💪
Very good video man! I love your enthusiasm and positive attitude!
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! 😆
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!
Yeah, I thought raising the engine would require an engine hoist. Not too bad of a job at all.
Great job, about to buy the same truck with a bad rear main. Pretty sure I can handle this. Very appreciative of your efforts
Awesome video, very informative and gave me everything I needed to know. Thank you!
Love to hear that! Thanks Kevin.
So glad 1st generation ram videos are here:)
this truck is beautiful! now i remember why i subscribed!
Thanks for being patient in between old dodge videos! 🤘
I have a 91 d350 with the same engine so I've been learning.
Thanks For the help now my truck is alot happier!
Dude thank you sooo much I've been waiting for this video for a while I'm sad I missed it when it first came out
Great video, Jason. Loved the quality of video, loved your attitude and honesty. I'm a new subscriber looking forward to seeing more of your work. Thanks for making this!
Thanks very much! Enjoy the back catalogue. :-)
This is a great video!! I am going to do my 80 D150!
Love love love it thank you so much for this content
I have one of these and I have no idea what I am doing when it comes to fixing it. Your videos have helped me a lot. Thanks for making these.
You’re very welcome. I’m glad I was able to make this video in particular. I couldn’t find any videos about this job before doing it.
@@JasonExplainsThings i actually have to replace my rear main seal so it was very good timing for this to pop up in my feed lol
Awesome work!
Thanks for the video. I found this incredibly helpful while doing the same job on my '72 Duster 360. Give your dad a raise lol.
He’s the man.
Great video I was going to do it the hard way without even looking at the manuals I was going to take the timing chain off and then do that I got to replace that seal anyways
AMAZING video Jason!!!!!!🤩🤩🤩 Thank You!!!
Very glad to help!
I'm going to be using this video to fix my 318 up with some new parts thanks so much
Get the manual as well! It’s a big help.
I'm in the middle of doing the timing on my truck(the exact color as yours too) and wanted to replace the oil pan gasket. Couldn't get the pan out because I didn't lift the motor! Also my rear seal is pretty much plastic at this point and isn't letting go 😭 hopefully lifting the motor helps! Thanks for all the information! I do like that you leave mistakes in so people know what not to do, it's helpful to know, like the ball joint video!!
you rule! thanks for making this
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.
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😂
Thank you. That was a very good video.
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!!
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.
@@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.
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.
That’s awesome. Yeah the manual said some do some don’t. Mine definitely did. Even with raising it things were pretty tight.
Great video. Thank you
You’re welcome!
Muchísimas gracias 👍
Thanks this was really helpfull
Great production values and making this video long enough to get all of the "gotchas" while still being short enough to follow. Great video, enjoy that truck!
Many thanks.
Enjoyed this my dude!
Thanks Raul! That was a scary project to start for me but I'm really glad I did it. More Dodge stuff coming in February!
Sounds like I ought to be teaching him! And my profession was a contract const Plumber!
Start a TH-cam channel dude! Maybe I’ll quit and just link folks to your stuff. 🤘
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!!
My exhaust is in good shape! :-) But thanks! Yes, more Dodge content will come for sure.
Man I love these old squarebody dodge
Lol I watched the whole thing... And I don't even own a truck. Awesome content man!
Awesome! Thanks. I watch videos about cars I don’t have too.
Nice truck bro
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.
Great video
Good job boys
Good job
Anyone know if this method works on a 4x4 2nd gen 2500 with the 5.9 magnum?
Thank you sm my rear main I believe just started leaking on me I started my truck to move it and there was a small puddle where it sat idling for a second and then I looked under my truck and it was dripping out the back by the trans 😭
The procedure in this Vid should also works for up to 90 3.9 LA. Thanks for the vid will be doing this on my 90 Dakota. Right now my engine is on a stand, so I'll be able to skip some steps. Procedure for rear main seal was very helpful.
It's nice that these "CHILTON" Manual's are really inexpensive on Ebay or at your Local Thrift Stores
Make sure you look BEFORE you wrench!
Great work👍
A FSM on disc is a few kopecks more and exponentially better. And what is 30 more if you lose the savings in a come back.
I have a 86 dodge ram d150.. I’m having problems getting the carburetor and lines set up.
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?
Just bought myself a 89 dodge w100 with the 318 engine and it’s lifted 4 inches on 35’s 😅 it’s tall so hopefully I can get my oil pan out without needing to raise the engine
This has helped me alot with my current situation but if i may ask for reinstalling the oil pan did you put a line of permatex on the pan sides at all or did you just mate it straight yo the cork gaskets?
I have a 1990 ramcharger 318 will this be the same process
Use a one piece silicone rubber gasket for a Magnum. Buy a piece of cheap thread all and cut it up into at least a half dozen studs. Buy a 42 dollar 1994 magnum pan from Rock Auto use a magnum pickup. Goop the mating surfaces liberally with RTV on the ends and sparingly on the sides. I have been using those old LA cork and rubber 4 piece sets since 1970 and never again . I did this yesterday Free ,I say Free at last
I need to do this on my ZJ with the 318 (5.2).
So what did you do with the seal/rear main prior to putting it back in
I seriously have to do this to my truck.
Eventually I'm gonna need to do this on my 79 W150, same engine. Seems about the same as my 97 Grand Cherokee.
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 🤦♂️
hey man I removed my mounting brackets to put in a new oil pan and I could really use a photo of your undercarriage of where the brackets go... I have 2 bolts left and I cannot for the life of me figure out where these brackets attach to because the bolts aren't fitting in where I think they came out... anyways I can't find any pictures online if you could help me out that would be fantastic... I have a 1993 w150
I have the 1987 Dodge d150 2 wheel drive 318 engine same color it was my father's who had it since 1996 and he recently passed away 2019 and it set for 5 years since 2017 recently got it in my name inherited and going through issues on getting it running again which it ran fine before it set having issues with fuel getting to the carburetor then change the fuel pump fuel filter few other things seems to be running a little bit better after I noticed a line was off underneath the engine still want to die out a little bit though also rear seal leaks major work we done to it is a timing chain and a steering wheel column besides that it runs like a champ it did thinking need a new carburetor rebuild kit or just new one in general it's the original Holly pushing over 300k miles but it's a beast still after setting for 5 years dropped a battery in it basically it's turned right on over
Thanks
HEy good instructional do you know if the same for the Cummins in terms of motor mounts and lifting engine?
I’d reach out to Decent Garage on TH-cam. He builds first gen Cummins. 👍
Just did this in my 84 ramcharger! This video saved me so much extra work trying to figure this out. I am grateful.
Thanks very much! I put this off for years because I was intimidated by it. I’m glad the video is helping others.
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
I can tell you that I did add the RTV in those spots.
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
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.
Oh that is so easy to do i thought i was gonna have to remove the tranny and clutch on my d250 i will have to do this some day when i get tired of toping off the oil. Speaking of that the dipstick tube broke in the block so its even more annoying.
That plastic junk that came out of the pick up tube was the cheap junk plastic/metal camshaft timing gear. Which means if you haven't already changed the timing set, you should.
Watch my short videos.
Can you tell me what manual/book you used to guide your changing the rear main seal?
In the description.
Hello again I’m working on my rear main and having a problem after taking my beating cap bolts off it won’t come off even with some light pounding, any suggestions? For a 91 dodge Dakota
Never mind! Got it ! If you move it side to side it will slowly release just takes time
Did you use black RTV to put in the new rear main seal
It’s shown in the video. From what I remember I put some black RTV in the spots notes in the manual.
I have the same truck but an 86 and I feel I have the same leak problem
For those who may be new to this stuff, Disconnect your battery before you go to remove the starter.
He showed that
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.
About how long did this take to complete? About to do this on a 88 w250. Also doing the trans pump gasket and seal! Wish me luck!
Good luck! 🫡 It took us 2.5 work days but that was filming the entire process as well… which slows everything way down.
Did you have any problems lifting from the balancer? I’m doing it but I have my balancer off. Was just going to lift on the crank nub with a block of wood between. Most people I ask tell me not to lift from the balancer/ crank just wondering why.
Weird, the manual I followed specifically said to lift it that way.
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
I just followed the procedure in the shop manual.
Did the rear main on my 1986 d150 with the 318... still leaks
Bummer. There are a few other gaskets I still need to replace... but this job tackled all the bad ones.
Hi Jason,
I have an 1986 D-150 5.2L- can you tell me how long it took to do the complete repair ? I have no garage on my own and need to rent something . So far I did my repairs outside..Many tghanks and greetings from Germany. Tom
It's hard to guess because I was shooting a video which slows everything down. I'd say for a first time job it will take you at least a full day, maybe two. And greetings from Washington State! :-)
What Carburetor is under the hood?
Stock carb... haven't messed with it much other than replacing the idler arm (which broke).
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.
I believe it is the same, but I'm not 100% sure.
Not a mechanic but am a machinist. I have a lot of experience hydraulic cold straightening. .0015 filler gage is a crazy 🤪 thing to do. The mill that made the lid is like huh bro?
😂
Hey Jason! Always happy to see the ol dodge, is she electronic injection or Carb? I'd love to see a video of you tuning the carb
It has the original carb. I'm daydreaming about adding EFI from Edelbrock or Holly.
@@JasonExplainsThings me personally, to see such an old truck in such good shape, I couldn't dare changing out the carb... I'm a purest hahaha
How many motor mounts are there? 4 right?
2 I believe.
Great video about to tackle this job myself. What did lifting the engine 2 inches do?
Gives you clearance to take the oil pan out.
@@JasonExplainsThings thank you
You’re welcome!
