In 1982, I went to work for the company that made all of Chrysler Corporation's air conditioning clutches, and got a brand new Dodge Aries company car, with the 2.6 liter Mitsubishi engine. More than 40 years later, I can't tell you how many times it left me stranded. Everytime it was towed to the dealer, it came back to me as defective as before. My regional manager asked me about it, and I told him. He apparently said something to the company president, because when I went to pick it up, the service manager at the Dodge dealer asked, "Who ARE YOU??!! Corporate called and told us to fix it or it's our ass!" Never had another problem.

I had one too. Saved my life in an accident where an idiot in a Camaro tried to make a left turn from the middle lane as I was passing him. Sent me into a curb and a guardrail. Broke the rear end, flung it into the gas tank. Pancaked the drivers side and bent the A-pillar. Crawled out of the driver side window NASCAR style. It was a strong car for what it was.

[@tmmurphy]

I recall reading at some point the reason I couldn't kill my mom's super (slant) six: Chrysler originally designed the Slant Six 170 to be an all-aluminum light weight engine. Metallurgy at the time was not sufficient to make that engine out of aluminum. So rather than scratch the design, Chryco engineers simply made it out of cast iron. The cast iron version built to aluminum specs meant the engine was over built and over engineered. Combine that with low compression tuning and viola, you had an extremely stout (heavy) and under stressed i.e. reliable engine, making hardly any power that would last forever. That used car (Volare 225 Super Six wagon 2bbl) outlasted me & my brother's wrath (140k) and went through two additional owners before I quit seeing it around town. I hated that slow, cream-colored turd, but also respected it. Now on that rare occasion that I see one, I view it through a different lense of appreciation.

[@61rampy65]

Chrysler did build the Slant Six block out of aluminum, but only on the 225 version, and only for a few years (62-64 I think, could be wrong, tho). The block was die cast, similar to the Buick 215 V8, but it used an iron head. Results were predictable; head gasket problems and corrosion of the block, so there aren't many around. I think Steve Magnante featured one before he got sick Edit: I also think it was optional to get the aluminum block.

[@user-xg8yy7yl1d]

Inline 6s made after the US ended lead gas had lower compression ratios to be on the safe side because so many i6 got used in industrial applications or by rednecks and farmers where they had to err on the side of caution that the fuel would be shitty and detonation prone. Nowadays that translates to those i6 being able to run on anything even alcohol or crappy old green gas

I still have a Reliant Hemi K wagon. When the car was pretty new, it was recalled to have it's heads re-torqued. Because my dad was retired and didn't drive it much, we got that done in time.... Also it has a crazy carb that races the engine for the first 5 minutes, which a very wise mechanic advised us never to fix... In as much as no one ever wanted to wait for the car to warm up... it still lives on today and still makes for a very handy wagon. But what still amazes me is that this wagon gets around 45 mpg on the highway at slower speeds. No, it's not quick, nor fast... and it does take forever to be ready to drive... but I've never had anything that gets the kind of fuel economy as the MCA Jet silent shaft hemi engine.

My cousin knew someone who had a car with a 225 slant 6. He built a 440 for it, and they decided to give the 225 a riteous send off by draining the oil and coolant and putting a concrete block on the accelerator. They started the engine. It ran out of gas.

Also, the 2.2 turbo New Yorkers. Geesh. Crazy torque-steer on turbo wind-up. Very unbalanced power curve but sorta fun to fight the steering wheel as it had a mind of its own when the turbo took over. At least I "Never forgot my keys" at the end of a road test since the car reminded me not to. The Mitsu MCA-Jet system worked great when it worked. The tiny rich mixture valve was about the size of a ball-point pen as I remember. It worked OK but as soon as a hack worked on that fuel system, it was over for that engine ever running well again.

[@keepyourbilsteins]

The dealer must have replaced the one on my family's Voyager 3 times before my grandfather decided to figure out what the hell was going on. Turns out the choke pull off was weak and the choke plate when shut would stick in the bore. 10 minutes later he had a safety wired limiter on the choke lever arm and the pull off never failed again in the 6 more years my parents owned it. Still started just fine in cold weather.

Hehe, bad? 318 Fuel injected, of course. I was a young Chrysler tech way back then. I remember the transparent air cleaner cover(a service tool) used to observe what I'd call the 'dripping straw' fuel injection system. Was that tool useful? I guess for the curious. I did get to perform one of the carburetor upgrades on an Imperial. The pallet of parts in the kit must hold the record for the heaviest weight service bulletin kits of all time. Engine was OK enough but performing an abortion on an entire fuel system seemed so crazy. Glad I was around then. IMO, the 2.2 and 2.5 were OK...just due to the simplicity.

I had an early 87 Caravan with the 2.6, I sold the van when it rolled over 200,000 miles. I did replace the cylinder head three times and it was ready for a fourth head when I got rid of it. I did pull the engine at about 140K and did a balance shaft delete and I never really missed them. Engine was a lot peppier after the shafts were gone. Only issue I had with the carb was icing during the winter. The heater motor on the air cleaner failed and would not put any heated exhaust manifold air to the carb and it would ice up. Dealer wanted me to buy a whole new air cleaner housing to fix it. I had several IHC Scout II Engines around at that time so I removed the motor from an IHC Air Cleaner housing and adapted it to the mitsu and never had any more icing problems. Some ways, I wish I still had that van. When they went to the Grand Caravan, I lost interest as they took up to much room in my garage.

[@gavinmclaren9416]

This was an excellent overview of the Mopar engines circa 1981. Our family was very much Mopar loyal at that time. I do have a few comments. In addition to the 318, the 360 was available in a few lines, especially 1980 model year and older, and commonly on trucks. The 360 was a pretty stout engine for the time, especially the E58 version used on police cars and famously on the 'Lil Red Trucks of 1978-79 model years. This engine was also used, although fairly rrarely, on earlier A-body cars; I had a 1975 Dart Sport with a factory-installed E58 360. This was a pretty quick car. The 318 was also offered in a four barrel version in 1981-82, using the Carter Thermo-Quad carburetor. The TQ was a great carb as long as it was not overheated. If overheated, the phenolic middle section of the carb would warp and cause all sorts of drivability issues. If intact qnd in good shape the carb would flow an honest 800 cfm, which IIRC was the biggest 4BBL carb that Chrysler used on any engine. It was used on all 340's from '71 on, all 360 4BBL engines, all 400 4 BBL engines, and all 440s from '73 on. The 318 4 BBL engine in 1981 used 360 heads, which had bigger ports and valves than tne 318 2 BBL engines. The 318 heads evolved considerably in the 1980s prior to the Magnum versions. We had a 1981 Cordoba with the 318 4 BBL. This car never ran very well until out of warrantee, when I scrapped the ESC (lean burn) system and rejetted the TQ carb. I also planed the heads to get some more compression, installed a conventional LA distributor with 36 degrees total timing, a 340 camshaft & valve springs, and a factory-style dual exhaust. This really woke up the 318, and the Cordoba ran much, much better, and felt like it had double the power. I also had a 1972 Duster for a time that had a 225 slant six. The mechanical valve lifters gave it a very distinctive sewing machine sort of sound. It was phenominally reliable. As some others have commented, the slant six was originally designed as a 170 ci engine with a 3.125" stroke, and the ports and valves were originally designed for an engine of that size. When the engine was stroked to 225 ci, the ports & valves were relatively undersize. This limits power on the 225, but the engine has higher velocity gas flow on the intake, which helps torque and smoothness of the engine at lower RPM. Except for some rare 4BBL "Hyper-Pack" engines in 1961-62 all slants had Carter 1BBL BBS carbs, until the "Super six" was introduced in 1975 or 1976 (can't remember which). This had a BBD 2BBL carb, similar to the 318, and I reckon was good for about 10 HP, a useful gain on a 100 HP engine. As far as I can recall, both 1 BBL and 2 BBL versions were available into the 80's. When the slant was converted from mechanical lifters to hydraulic in 1981, the engine also changed from a forged steel crankshaft to a much lighter cast iron crank and the balance of the engine was changed accordingly. Many bottom end parts are specific to the version of the engine and are not interchangeable. I have lots of good memories of the '80s, but the Mopars of those times were moving away from the 1960s and 1970s of ny childhood and I liked them less and less as time went on. I think now that Chrysler was hurt more than GM and Ford by the on-again, off-again high fuel prices and the relentless CAFE and emission standards of the time.

[@donreinke5863]

Apparently, Carter discontinued the Thermo Quad in the 80s and four barrel Mopars were afterward equipped with Rochester Quadrajet carburetors. Used to see them on Dodge pickups with 360s. The 1971 Ford 429 Cobra Jet also used a Rochester Quadrajet, while the Super Cobra Jet used a Holley.

[@gavinmclaren9416]

@donreinke5863 That sounds right to me, although I have never seen a Mopar with a factory-installed Q-jet. I recall Carter going through reorganization/bankruptcy after the big three all moved to fuel injection, and I reckon that's when they sold the rights & tooling to Edelbrock. I do recall the 429 CJ with the Q-jet, a friend of mine bought a Torino Cobra with that engine and we were both surprised to see the typical GM carb on top of the Ford engine. We both assumed that it had been swapped on, but a little digging revealed that it came from Ford that way.

[@grassblade63]

The Slant Six, or "The Leaning Tower of Power", was always a favorite of mine. We had many of them in Air Force fleet vehicles and equipment, and seldom had to do more than scheduled maintenance on them. They will outlast a 300 inline Ford, and that's saying something.

[@platinumuschannel]

I dunno, when I used to live out west, I had a roommate who worked for an oil company. I guess their pumps were powered by the Ford 300 I6 and they ran 2/7/365 and were only stopped once every other year for an oil change. Their timing is literally just two gears- no belt/chain. That's pretty damn impressive. I don't even see Toyota pulling that off. By the way, I'm not knocking the 225. That's still a great engine. Better than anything Chrysler has today in terms of durability.

Other than that, is was a reliable car. BTW, my 1969 Slant Six Dart had 145HP and could smoke the tires, and my 1968 Barracuda (318 2BBL) had 230HP, built before the Oil Embargo and smog emissions.

The float was soaking up gas like a sponge and becoming too heavy, so although it would still float and appear to be working correctly the level was way off because of the extra weight. It was very obvious once we compared a new float to the bad one, but because it looked like the bad float was working it took a few tries to figure it out.

When driving the van I just moved the engine cover off whenever the engine started rapping and add a couple of quarts of oil I kept nearby without even turning the engine off. One day after many miles the engine won't stop rapping and that was that but it owed me nothing.

Just something silly to put out here which is completely irrelevant today: I personally remember as far back as the late 80's that rumor had it Mitsubishi Japan was not at all thrilled with the Mopar implementation of their 2.xL engine which was not quite made to the same spec the Japanese version was (out of necessity).. You'd find the Mopar implementation in anything from K variants to Might Max/D-50 1/4 ton pickups to US Spec Mitsubishi vehicles which all had that American-Chryslerized version as part of the Chrysler Mitsubishi arrangement. By the end of production the best version of this motor was probably in the Japanese imported Starions which did exist here and there.. Not all US bound Starions had the Americanized engine, and that was one hell of a cheap thrill. Just a joy to drive and own. Much like the Eclipse that came after it. FWIW probably the absolute worst of the worst version is what came in the early Dodge Ram 50 (D-50)/Mitsubishi Mightymax pickups from about 82 to 86 which my family had a few of. Name a possible issue, it had all of them. Garbage engine no argument

A friend of mine bought one of those J-bodies with a dead FI set-up in excellent shape for $300. Used the tank out of a Gran Fury, removed all the fuel injection, installed a Walker 40430 Y-pipe, 3" Catco catalytic converter, 2.5" exhaust & an NOS Magnaflow turbo muffler, put the electronic ignition with the GM ignition module (the one from under the cap), Edelbrock 4-bbl intake, TQ carb (he can build & tune them). That car still runs, better mileage than when new, and I'd challenge your opinion on the "Only get the dealer converted ones"- this friend is a phenomenal mechanic/tech/builder. This conversion far outperforms the dealer version

The Astron 2.6 was used in the very popular Sigma and Magna sedan and wagon models here in Australia in the 80s. I never knew it as a bad engine but maybe with neglect it was, the cars were plagued more with auto transmission failures. Certainly, the old Valiants with the slant 6 were very dependable.

Concerning the diesel blip around 1980: I was working part time pumping gas at that time. It was just after 2 gas shortages in the 70s and at least in my state, there was a law passed to limit the profit to a certain number of cents per gallon of gas. Coupled with the bad economy at the time and rents, insurance, etc. increasing greatly, it was a tough time for station owners. My boss was once fined for raising the price of gas at the pump before the tanker had left the property. When the diesel cars were gaining popularity, stations that sold diesel fuel were few; almost creating a monopoly. With no regulations on diesel pricing, it was a chance to finally make some income.

Adam is spot on with this assessment. When I was in the used car business, I wouldn't buy anything at auction with a Mitsubishi engine. We provided a warranty and felt we couldn't stand behind the product. Therefore, we wouldn't sell it to our customers.

[@kevinbarry71]

Speaking of that Mitsubishi 2.6 L, my father bought a 1987 Mitsubishi Montero which had that engine. The carburetor was definitely a problem. And later on the upper radiator hose seem to lose strength and fail internally. Causing a blockage. Causing a cooked engine. Not good. We did end up tearing down the old engine, and I remember how it was built. Using chains for the oil pump, the camshaft, and another one for the balance shafts. A good engine, when it worked

[@FULLBOAR]

Funny, those 2.6l Mitsubishi engines had a pretty good reputation in Australia. They were found in the RWD sigma which was Australian assembled. I think AUS emission regulations were more lax in the 70s and the engine wasn’t covered in vac hoses and had a less complex carburettor. I won’t say they were faultless but they definitely weren’t maligned here.

[@CAROLDDISCOVER-FINDER2525]

I just finished watching the rest of your episode. I find it interesting that you got it backwards. The major problems with the 2.6 where is cracking of the heads parrot and they almost always cracked in the same couple of places. How do I know that? We weld it many aluminum heads various manufacturer and engine sizes. If you knew what you were doing after a little bit of practice the air valve as you called it really came in handy. As far as the carburetor as long as you kept it clean it's like an Opels carburetor back in the 60s once it went South it was junk. The balance shaft had to be the number one problem. There was a bypass kit and you can use the same chain tensioners everything just had a gear and it had no shaft. Once you did that the engine ran so much better. Yes it was complicated behind that timing cover. I called a pinball machine. BECAUSE it look like a skeleton x-ray of a pinball machine. All the bumpers flippers and so forth. In this case on the engine we're talking about guides and so on. Not only did we work on these for other people but I drove these Mitsubishi 2.6 is and also the 2 L quite a bit during those days. As far as the fuel pump, can't remember a time we had to replace one. Back then we would run double filters and tell her customers we recommend the same. Of course when you have an aluminum head and a non-aluminum block that created problems especially back then. I really think overall they could have done better and they really really killed himself in long-term during the eighties. Any of the BIG 3. But then I'm also the nut that would like to have a second generation or 3rd generation 350 Oldsmobile diesel engine. I had great luck with them as well. I would literally drive one today and would love to have a 98 regency brougham preferably burgundy to maroon in color. As far as the slant six and the 318 yeah you nailed it. Some of the older slant six is had their quirks that they worked out. Did you know that Toyota had a hemi engine 4 cylinder about 73 or 74 is when the imported it. Only a couple of years. I really did appreciate and like your episode here.

[@drippinglass]

The /6 was pretty reliable stock. But with only 4 main bearings for the crankshaft, it’s not an engine that is built to be modified. The AMC 258 straight 6 has 7 main bearings in comparison.

[@timothykeith1367]

A 225 seldom sees more than 3,000 rpm because the restrictive head doesn't flow well. The low speed nature of the 225 is the reason for its longevity. If Chrysler had the resources to build a lighter car - the size of a BMW E30 - the short stroke 170 might be more loved today.

Thanks for this video. I can attest to the durability of the 318. My very first car, 1970 Satellite, had one. I drove that car 10 years (1980-1990) and had no problems with it ever.

We had a mid 80's Dodge lancer with the Mitsubishi motor. The water pump was on the back of the engine and ran off a belt that was driven off the back end of the overhead cam. Also no automatic brake adjusters.

[@adamtrombino106]

Nothing bad to be said about the Mopar 225, 318, and 360s of the time, IMO, other then they used lots of fuel when looking at their mileage and acceleration. The 318 EFI is the exception, but that was an electronics issue. The Mitsu 2.6 was horrid, with everything this video said to be true. Getting a replacement head proved to be rather difficult in the 90s. I recall our shop being on a waiting list for months. And good luck if they couldn't pass an emissions test as all controls were vacuum electro mechanical, with miles of lines that would make an Olds 307 blush.. My big gripe here is how bad the early 2.2s were, and the turbo variants through late 85. Chrysler had a major recall on all 1.7-2.2 carb cars starting in late 83 and lasting until late 84 for 1.8 million vehicles for stalling and poor performance. The Holley carb was the issue, and they never did get that 1 fixed, just flung a new 1 on. The 86 and up got new larger headbolts for the new fast burn head, several different types of gaskets were used to fight leaks, new cams made of better material were employed, better oil pumps, new and more simple distributors ( I believe 87 and up) larger engine mounts, and simple low pressure Bosch single point TBI 86 and up which worked very well. What they never fixed was the mechanical timing belt tensioner. Belts stretch! Plus side, it was an non interference engine, so if the belt broke, no harm done. ( same for the later 2.5s) Minus was the belts did not last long, about 50-60k. On the short lived 2.2 turbo 3 series with the Lotus 24v head, this was an issue as that was an interference mill, and that was expensive to fix if the belt slipped or broke. The 2.5L was a better engine, with the balance shaft, and better connecting rods, as well as less head gasket failures. By the early 90s, Chrysler had nearly all issues with the 2.5s fixed, even in turbo cars.

[@Vegaswill714]

Agree with Adam's take on the Chrysler engines, though I have no experience with the 2.6 liter. The 318 was my favorite, I had one from an earlier era (pre lean burn) and loved the way it drove. The 225 slant six was an engineering marvel. I knew of several that went over 200k miles, knew of one that went 500k miles. They were not powerful but had sufficient torque to move the lightweight cars of the era very nicely. My dad had an '81 Dodge Aries with the 2.2, it was very reliable and ran well though the car was underpowered. I remember merging onto the freeway with four passengers was a white knuckle experience.

[@emjayay]

The 273/318 V8 was based on the original Plymouth and Dodge V8 from 1955 with polyspherical heads that also ended up being a 318 for years. It was lightened with wedge heads and precision casting in the new version. The poly version also had mechanical valves at least through the early sixties if not to the end.

[@RichieRouge206]

Great video

[@marko7843]

I always called the 318 the Slant Six of V8's! In fact, before the emissions strangulation in the mid '70s, they both made more power than they had any right to as well as being reliable... (I'm flabbergasted though, that the Six didn't have hydraulic lifters all those years. I don't ever recall one rattling badly, and I drove a Duster that was beat to death as a pharmacy delivery car...)

[@danleveillee2202]

I was a certified Chrysler/Plymouth tech in the early 90’s. I can definitely attest to the fact that the engines at that time were embarrassingly unreliable overall. The 2.6 most commonly had timing chain and carb issues. The 2.2 had wrist pin knock and ate head gaskets, (and even worse after being replaced once, because they need to be torqued and retorqued later after replacement, and Chrysler and indie shops never bothered to do it.) The updated 2.5 version of the 2.2 4cyl that came later was actually pretty decent (the balance shaft helped a lot too). The turbo versions of these vehicles were unspeakably horrible. That’s all I’ll say about that. The Mitsubishi 3.0 V6 had egg shaped cylinder wear issues, and thus nearly always burned oil past the rings by the time they had roughly 75,000 mi. on them. The 3.3 that came later was halfway decent, but was unfortunately backed up by a disastrous 4 speed electronic transmission that was lucky to make it off the lot as a brand new vehicle. The slant six was pretty much beyond reproach, with the 318 following close behind. The fuel delivery issues Adam described were spot on. If you buy an older Chrysler product with a ballast resister, always keep a spare. Though there were a few decent products in the 80s, on the whole, I found it to be a very embarrassing time to be a technician for Chrysler. One stand out vehicle that I remember from that time was the Dodge Omni with a German made 1.7 VW engine. Those little cars were definitely hard to kill, and Chrysler would have done well to stick with that partnership. Sadly, I can’t really name a vehicle from that time that I would have been proud to own, unless it was in the truck line. This was a great, accurate video Adam!

[@Humandriver5280]

They should have used the fuel injection from Bosh. The in-house fi for the Imperial was costly for them. Cadillac used a Bosch system in the DeVille w halfway decent results.

[@donreinke5863]

Ironic...because Chrysler invented electronic fuel injection back in the late 1950s. They didnt work because the control units werent shielded, and driving near a magnetic field such as a large neon sign would cause them to stop running. Vehicles so equipped were subsequently converted to carburetion by dealers. Long story short...Chrysler sold the system and all intellectual property to Robert Bosch..the rest is history.

[@craigbenz4835]

The maintenance schedule for the solid lifter slant sixes called for the valve lash to be readjusted every oil change. Of course this was rarely done, but would usually wake them up quite a bit.

I remember those 2.6 Mits engines, they did run good. Had one customer (back in '84) who had on '81 K car with that engine, the ignition igniter (ND dist)failed lost all spark. We had to get the replacement unit from a dealer because at the time it wasn't serviced by the aftermarket yet. Remember the part cost was astronomical for the time, can't fully recall by it was around $200. After the repair the customer continued to drive that car until he traded it off in '87. If I recall they used that same engine with a turbo in the Chrysler Conquest back at that time.

Chryslers choice to discontinue both the B and RB engines in 1978 cost them severely in Dodge truck sales, as Chevrolet/GMC continued to offer their 454 in 3/4 ton and heavier trucks. Also, Ford continued to offer the 460 in trucks up to the 1997 model year. Winnebago..apparently had a stock of RB engine equipped chassis and used them into the 1979 model year. 440s would easily hold their own against nearly all "7 liter" engines (427, 428 and 429) as well as 454s, 455s and 460s...and were more durable.

The Chrysler Engineers were kept busy during the 80's, trying to adapt to Emission Standards, while coming-up with something innovative in Mopar Engineering. Sometimes they got it right and sometimes they didn't, eh Adam🤔🤲

I believe that Chrysler should have kept the R body. That car would have caught on. Understanding the bankruptcy issues and all the rest of it - Chrysler had something there. Too bad really. 225/318/340/360/440 all great engines. I heard from more than 1 person the 426 was a rough runner. Chrysler had engineered excellent engines, too bad they didn’t go further ! Thank you for this video Adam
