- Join me as I dig into this dirty junkyard 360 Magnum. I'm tearing down a 1998 Dodge Magnum 5.9 liter engine sourced from a Dodge Ram with 150,000 miles. My goal is to inspect and assess its condition for a potential replacement for the Dart's 273. Watch as I carefully remove components, inspect cylinders, pistons, lifters, and camshaft. Stay tuned for the thrilling moments and surprises inside this engine. If you're into teardowns and engine inspections, this video is a must-watch!

No worries brother! Glad your out there doing what you love no matter what...nothing but love for you man! My hands/fingers started tingling a decade ago so I have to be careful Life of using my hands in the HVAC trades. Have fun, and I'll be watching for more fun stuff!
Thank you. I look forward to seeing you around.
A good thing to check when buying a junk yard engine and can't hear it run just remove a valve cover and see what it looks like under it if it was taken care of it should be relatively clean but if it is full of sludge and burned up oil go and look for something better because that engine is more then likely all wore out because no one bother changing the oil on a regular basis
Thanks for the advice. I didn't think about that at the time. I should have brought some tools to take a better look at it before I bought it. I am glad it turned out as clean as it was though.
I have one that’s the same this was a good tear down video that I will most likely be using to tear mines down
Hello Damien! Thanks for the comment and welcome to the channel! I am glad you found this video useful. If you have questions, feel free to ask. I will be happy to help out the best
I can.
Some free info. You can use the magnum 1 piece pan gasket on an LA engine if you use the magnum pan from the same type vehicle. Won't work with your Dart though. I have been trying to figure out a way to use the magnum gasket on an LA pan, that ridge on the curved part of the pan is a problem. Rod numbering: I stamp the number on each half of the rod at the split line on the side that is visible from the bottom, helps prevent mixing the cap & rods. Rods will go in only one way, large chamfer goes against the shoulder of the crank, always. Oil pump same as the LA except for the pickup. Surprised about the lack of cylinder wear? I have rebuilt 4 magnum engines so far, minimal cylinder wear. Magnum & LA truck blocks are all made of hi nickel iron. The FI saves the cylinders from excessive wear. In cold weather a carbureted engine will run very rich until warm washing lubricating oil from the cylinders. Please, please get a long breaker bar to crack loose head bolt & main cap bolts. Using your hand as a hammer will ruin the feeling in the hand and that is not good. Been there, done that & not good.
Hi Larry. Welcome to the channel and thanks for the great info! I am mostly trying to disguise this engine as an LA so I went with a 360 LA pan. Most of the info on the gasket came from www.magnumswap.com. This is only my second engine tear down, the first being an LA 273 which was not in nearly as good condition so I was pleasantly happy about it. I will definitely take the rod cap stamping tip onboard for future builds (there will be more.) I learned about the chamfer while rebuilding the 273...the hard way. Lol. I will also keep the tip about a breaker bar vice my hand in mind. I haven't had any problems yet, but don't want to. Again, I greatly appreciate you sharing your experience and I hope to see you around.
@@MontsweagGarage As I said before I have built about 4 of the magnum engines, 2 complete rebuilds, on 2 I changed the timing chain & gears & cylinder heads. One was the 3.9 V-6. That was way back when you could get the Engine Quest heads made in Australia, not anymore. I've been experimenting with a way to use the one piece gasket on an LA pan but that ridge on the curved end is a stumbling block. That magnum gasket works great, seldom leaks. I have built many 318 LA engines over the years and one thing that I have noticed about the magnum blocks is that the casting quality is much better. Keep up the work, those are good engines, solid & durable. Latest LA block I have built is in my 88 class B camper. 360 LA with Quadrajet 4 bbl. and reground flat tappet cam done by Oregon cams. Had them grind it to a Melling RV grind. Made a 3,700 mile trip in it in May & only used 1 qt of oil. That is in a heavy vehicle towing a Fiat 500 over the Rockies. Good luck with your project.
They say rods wear on the top mains wear on the bottom great video an build an a lot of good information
Hello Thomas. Thank you again for the comment. I am glad you got good info out of this video. This was only my second engine teardown and I was really happy with how nice the inside was. My first was the 273 that came in the car and it was a sludgy mess with what I think was lead deposits from the leaded gas. The 5.9 sounds amazing and I can't wait to get it in the car to see how the power improves.
Nice clean 5.9. I am building one as well for my van as a tow rig.👍😎
I was really happy with how the inside of the engine turned out. I know going on that a junkyard engine was a gamble. I won....this time. lol. Parts are starting to filter in so I hope to be reassembling by next weekend. Good luck with your van build. I will definitely check out your lifter cleaning video. My last (and first) engine had solid lifters so I have no experience with hydraulic rollers.
to quote old pegleg himself this motor is a freaking sweetheart! :)
Welcome Robert and thanks you for the comment. I was totally stoked about the inside of the engine. Especially after seeing the outside. I am even more stoked now that it is running. Just need to get the rest of the body and frame work done so I can get it slapped in and take it out for a spin. =)
Looks like you got yourself a nice score on that Magnum, someone took pretty good care of it. It would have sucked if you opened it up and it was full of gunk and had a crap load of wear.
Welcome Back Chumley E! I knew it was a gamble and was elated when I cracked it open. Kinda bummed I wrecked the cam bearing but I need to learn how to replace those anyway. This engine is going to take a quarter of the work to get cleaned up and back together. Just need to get all the measurements to see how much play I have for a quick hone and what I need for bearings and such.
hold the number punch with the vice grips
Thanks for the tip Arthur. I will definitely keep that in mind for next time! Didn't occur to me at the time. I am still kinda new at this. Learning quickly though thanks to folks like you. I greatly appreciate it.
Ive got 2 5.9 magnum 98 rams..... Need 2 transmissions and 2 engine rebuild kits. 🤭 Among other things. That truck u pulled the engine out of may have needed saving as well the paint still looked pretty good. 👀
Unfortunately, I only have room for one project at a time. Lol. Some day, I may do a dodge truck. Probably be a 60's D-150, though. I am partial to mid 60's to early 70's vehicles, but the more durable power plants.
@@MontsweagGarage I got room for a small junkyard..... Can't afford to fix anything major when they break engines transmissions or diffs tho so I don't do that. Would like to do a 72-78 dodge truck at some point.
The hope is that in the next year or so, I can build a dedicated shop and take on more projects. I too wouldn't mind a 72-78 Dodge Truck. No matter the year.....probably gonna be a hemi swap =)
18:20 do any of those exhaust manifold studs penetrate the water jacket?
Hello! Thank you for the comment and welcome to the channel. Unlike the LA engine, the holes for the exhaust fasteners in these magnum heads do not pass through to the water jacket. I would have put sealant on them if they had, like I did with the water pump.
THANK YOU!
@@n6mz You are quite welcome. I just looked closely (with my glasses on) at the video this comment was on. I thought it was on the build video which is why I mentioned the water pump. Lol.
Do you plan on a cam swap and are you going to a carb setup.
Hello Ron! And Welcome! The plan is to go to a carb setup, at least initially. Once I have the money saved up, I want to put a sniper EFI system on it. I would like to beef up the cam but I need to be careful since I still have the 7.25 rear end in it. It is a SureGrip so it will hold up a bit better than an open unit but still don't want to explode it on the initial burnout. I have a lead on a 8.75 but nothing concrete yet.
geez buy a breaker bar head bolts making noise good thing not overheated
Hello Stephen and welcome to the channel. I get this a lot actually. I try to balance purchasing new tools, and purchasing car parts. I tend to lean towards parts, and make due with what I have on hand. A breaker bar is on the list of things I should probably pick up soon. Especially after taking the front suspension apart. Lol. Hope to see you around more in the future.
Bro…..buy yourself a breaker bar to do work on head bolts like that.
Why destroy ratchet and hands??
Good morning Joe and welcome to the channel. Thanks for the comment. I'm sure I will eventually pick up a breaker bar. It was kind of a make due with what you have thing at the time. You are not the first to mention hurting my hands. Never thought of that really.
I find it funny you use heat on the heat shields that are a big pain to remove and no heat on the manifold bolts. Is this your first engine teardown before?
Welcome back @79tazman. This is actually my second engine teardown. The first was the 273 that is in the dart now. It did not have heat shields though. I did use heat on most of the manifold bolts. The 2 that I cut off were due to the bolt heads being so round from corrosion I couldn't get a socket on them.
That engine is factory if it was rebuilt there would be 30 over pistons and those are factory 360 pistons so that thing is as factory as factory get's the timing chain is a wear part and has been replaced before but all engines with that many miles would have a the timing chain replaced.
Hello again @79tazman and thank you for commenting. There were a few things that made me wonder about it being rebuilt, or at least refreshed. The main thing was the cylinder numbers written on the rod caps with sharpie. Is that normal for a late 90's engine?
👍🏻💯🇦🇺
Thank you Brian and Glenda. Welcome!
I only had one fail on my exhaust bolts on my magnum. Blew my mind. 250k miles, and only one seized. The next day, i put a set of headers on a 3 valve triton with 100k less miles, but it only had one that wasnt seized.
Hello Brad and welcome to the channel. Thanks for the comment. I'd be willing to bet the addition of antisieze makes some sort of difference. My 273 had 1 stuck/broken off after 55 years and they were slathered with the stuff. I plan to add some the next time I have the headers off (installation day!)
