Looking for 6.2 & 6.5 info
 

Does anyone know 6.2 or 6.5 diesels on here ?
Not my favorite diesel, but Im told some 6.2 and 6.5s had steel cranks ?
If so can you ID them in the engine by the flange ?
Im needing a lightweight diesel , and a inliner wont fit without alot of modifications.

I don't know those engines well enough to answer your question, but www.thedieselpage.com is the expert site on those engines. LOT of archived info there to dig through.

'Course, if you REALLY want lightweight, it's hard to beat a Duramax with those aluminum heads. :)

Duramaxx would tear up the driveline with its torque.
And yes Mike, I drove a Duramaxx recently and was impressed with its power.

the "black engines were the better ones. if irc they came out in late 83. i've got one in my 78 4x4 it's turned up to the ragged edge of smoking bad, has decent power, runs well and pulls over 3mpg with a straight 4spd,4:10's and 33" tires in a 6k# truck.


mike

I was just yanking your chain with the duramax comment. :)

I really would check out the diesel page, though... there are probably hundreds of members there who could answer any question you might have on the 6.2/6.5 right off the top of their heads.

I know.I'll never hear the end of that. I have heard of some Duramaxx issues; there is a coating they used on the heads to prevent corrosion and some owners neglected to change the coolant when they were supposed to. It would eat through the coating, but thats on the owners, not the engine. 6.9s and 7.3s can calvitate in the rear cylinders by the same neglect -

Thanks for the info, Mike -
Im dropping one in a old Land Rover pickup; it has a underpowered 62 hp 4 cylinder diesel and they make conversion kits for the 6.2.

you'll like the 6.2 in that l/r, jsut gear it to take advantage of the torque band. i know of several blazers that pull 25mpg on a regular basis. the mechanical pump 62/5's are a good engine they just aren't the powerhouses the newer ones are.

mike

Mike, Ive always heard the 6.2s forte was 20 + mpg. 62 hp to 135 + hp will be night/day, though. I laugh everytime I hear a newer diesel owner (Duramaxx, Cummins, Powerstroke) tell me they get 30 mpg :pound:

A friend of mine has a 06 duramax and he is lucky to get 12. my 82 6.2 got 28 hwy and 25 city. I wish I still had that truck.

I had a 6.2 in a heavy 3/4 ton no OD trans and still pulled over 20 mpg and it didn't matter if it was fully loaded down and that was with 225000+ miles on it.

They have 'em turned up so high (365 hp) from the factory these days. If you buy a Duramaxx in some motorhome chassis I think its 230 hp or something like that.
I read GM had an economy 6.2 in step vans that was less hp for fuel economy

All of the 6.2's I've been into had iron cranks. The turbo charged 6.5.s are supposed to have steel cranks, but I'm not sure?

The 6.2's come in several "flavors", very early units have different rocker arm set-ups, water pump, etc.

None of those engines are overly impressive, in any configuration, and every single one I've had apart had major cracks in the pre-combustion chambers, and some across the exhaust valve seats.

Those engines are NOT direct injected, or did they have intercoolers on the later turbo charged versions, they are basically considered TURDS in the diesel world, at least compared to other designs. Some folks have still spent the time/funds to get some pretty impressive power from them, so they do have some potential.

The later Duramax engines, at least those I've driven, are much better, but seem to be pretty thirsty. We took a friends 2005 Duramax to Daytona last year for bike week, pulling a small trailer with 2 bikes in it, and it never did hit 10 miles to the gallon! It's pretty much "stock" except for some sort of "chip" in it......Cliff

The iron cranks are bad about breaking around the 2nd main cap.
If I can find a 3.9 Cummins BT I'll go that route -

as long as the 6.2's not turned up until it smokes like a coal burner it's efficiency increases with turning up the fuel as long as the advance cam is adjusted also. you don't want to get crazy with the advance but a little goes a long way.

the step van version was severely underpowered.

i've seen a total of 2 cranks broken in a 6.2 that were n/a. the banks kit really wakes them up but it'll also spit the crank out of the block in short order if the engine's run hard.

i've seen more cracks in the main webbing of the block and gaulding of number 8 cyl than i've seen other issues.

i'd be on the hunt for a ton truck as a donor. the non emission version, no egr, will be the snappiest of the bunch.

as i said above, they're not a duramax but iwth some care they're a good engine for a driver. i've actually thought about stuffing one in a mid 70's pontiac for a driver.

mike

Mike, If I drop a 6.2 in I have a complete set of the red headed stepchildren of diesels : Olds 5.7 and IH DV-550, though both run real well and earn their keep.

the 5.7 must be a later model. i've seen those run a LOT of miles. in fact i know of one right now that runs well in a mid 80's park ave.

that binder engine kind of scares me, i've not heard a lot of good about them. i like the dt466 and dt366 for an international engine.


mike

Despite low miles it has a later "WX" replacement block (deeper holes tapped for main bolts) I bought it with a bad headgasket: Ended up removing the block and installing ARP studs. Im averaging 30 mpg running the A/C.

I have a later 9.0 which was a somewhat improved DV550. 550s & 9.0s are gutless : about 180 hp and they are L-O-U-D when climbing a hill loaded. The DT466 is probably the best medium duty diesel ever made.

that's my opinom on the dt series of engines also. the 366 can be made to run well but it takes a little tweaking. i've got it in my head that i'd like to stuff one in a vintage binder pickup or shorten my co1600 down, stick one in there and use it to pull trailers.

i know a guy who's in the process of changing a 9.0 in a payloader. he's not having any fun with it and is hoping the one he bought is a good one.

mike

They made several displacements for the 466 series: DT360, DT408, DT466, DT530 and now DT570. I think DT stood for "Diesel Turbo"
It started out as a farm tractor engine in 414 cid in the 1960's.

The 9.0 has some good points: easy to start when cold, and suprisingly decent fuel economy. If your friend sells that extra 9.0 tell him they are in high demand with the tractor pulling crowd.

I'll pass that one re the 9.0's.


i think you're right on the dt designation, and ih put them in everything at one time or another.

as someone else said, the dt series is the sbc in the diesel world. as long as the liner seals don't leak they run forever.

mike

If I end up buying another medium duty truck, I'll buy a 466 powered IH.
Is that R185 a 406 or 450 inliner ? They also made a 372 & 501 if I remember correctly.

A 4BT is an excellent choice, reliable power in a package that will fit your application.

my r 190 dump truck has the rd 450 in it. talk about a fuel swallowing torque monster!

the r 185's got a rd 372/ 374 on lp in it, supposedly overhauled shortly before it was parked. it's followed up by an overdrive trans which i want for a hauler project. it also, curiously enoguh has air brakes on it. if this thing's tight enough i may stuff a dt466 in it and run it.


what i was initally on the hunt for was a 50's "s" series cab and clip to swap over on to an 1800 series school bus chassis.i had a NICE 54 r160 bought and the guy backed out of the deal at the last minute on it.

as you can tell binders hold a serious interest for me also.

addictions are terrible!

mike

Dont they have the Scout Nationals in Indiana ?

Im told many give good service and fuel economy in step vans; what kind of hp/torque can they make ? They make 6.2/6.5 conversions for Land Rovers, but if I could find a good 3.9 for a reasonble sum Id go that route.

They can be hopped up just like their big brother 5.9. Pumps, injectors, turbo...I'd get a P-pumped engine if you're looking for power. You can get 350hp/500 lb/ft pretty easily from what I understand.
I was going to put one in my FJ40 until I got a steal on an LT1.

I was going to find an aluminum step van, take the 4BT and cut the body up for scrap and try and break even.

Good forum here,
http://www.4btswaps.com/forum/index.php?

i don't know about the scouts but the ih nats are held in springfield, oh. it's about 2 hours from me.

mike

i really need to get on repairing the floors in my diesel scout. it's the first one that ih engineering dept in ft wayne stuffed a nissan diesel in. i know the guy who bought it intitially from havester. it should pull a little better than 30 mpg.

One of these years I need to go see that. . . . .

Thanks, hell 200 hp would be more then enough for what I have.

That little nissan will get 30 easily from what I've heard.
I had a gasser scout II awhile back, I always dug the binders for their 4x4's.

They used the 6-33 in forklifts and other industrial applications.

Speaking of forklifts, I just pulled a 2F out of my fj40, and it was propane powered.

Im already sold on that engine; now I just need to find a reasonably priced one.

The old Landcruiser 6 banger sure has a striking resemblence to the old Stovebolt Chebby'

i have a 1998gmc with a 6.5 turbo diesel i use these guys for parts and info
http://www.ssdieselsupply.com/index.html

So much in fact, I converted it to a GM HEI I pulled off a 77 Nova inline 6. All I had to do was swap the gear and have the flange machined off. I believe the oil pump is a bolt on too. The one I pulled from my cruiser has well over 300K on it.

The Toyota engine was knock off of the Chevy, GM sued them and collected fees for every one sold.

I had a 1982 Suburban with a 6.2. I bought it in '89 with a blown engine, the oil plug got left out at Jiffy Lube and it still went 20 miles before it broke! When I got all I could find was an engine from a medium duty truck, I used that, got a buddy that worked for Mack to tune it for me. That thing would smoke a 454 3/4 ton truck, both figuratively and literally! It was a 4x4 and would smoke the rear 32/12.50 BFG's with only 3.42 gears. It had a 700R4 from the factory but the torque killed 3 of them so I went to a t-400 until I got a pro built 700. A couple of years later a hurricane dropped a huge limb on the truck and totalled it. I put the whole drivetrain in my '75 Scout II. Talk about a beach burner!!!

Except the "knockoff" was much more reliable than the original :pound:

Have a link to where they sued?

i've got a gas 4cyl scout waiting in the wings also along with a 57 a-100 pickup, a 67 1200 4x4 and a 68 1100 4x4.

binders and pontiacs make a lethal combination!

mike

Hey Mike, if you have any pics I'd love to check them out, binders are cool.

Pics - I'll try to dig some up also.

You guys are gonna make me work now.

I'll have Jen resize what I have so they'll fit here and I'll take some more.

When I do it I'll start a new topic that way it won't be cluttering this one any more than it already has.

My 57's been sitting in my barn for 20 years. I'm not sure a good pic of it is possible. The others are in the open air barn so they aren't a big deal.


On a related note,I had the 1700 series loadstar running tonight that has the turret crane on it. The engine sounds pretty healthy mechanically but needs the tune up finished. No knocks or smoke and 40 psi of op at low idle. The crane works also so either way it's not a bad deal.


Mike

Sorry, this is all I could find and the link is dead;

I have seen many variations of that, and believe that it is a copy as well of the chevy inline 6. I, nor any of my cruiser enthusiast pals have ever seen any factual account of a lawsuit, despite hearing claims once in awhile. Just curious about a missing piece of history.

Didnt the Toyota engine come out in the 50s ? It looks alot more like the "Stovebolt" Chebbys (216,235,292) which had 4 main bearings vs. the 7 main bearings used in the '62 & later 194,202 (Sold in the UK),215,230,250 and 292 cid engines.

I know they imported the fj25 in 58'

Gas Land Cruiser engines are manufactured by Toyota. The F and 2F engines were also used in Toyota Forlifts. The F engine is supposed to be based on the Chevy 225 I-6 "Cast Iron Wonder" and some of the bottom end of the engine is rumored to be interchangeable. The main differences between the F and the 2F are the 2F's larger bore, the F's 2 compression and 2 oil rings versus the 2F's 2 compression and single oil ring and the fact that the F had two oil paths--through the filter or through the engine compared to the 2F where all oil had to travel through the filter before the engine.

The 235 had 4 main bearings; did the Toyota use 7 ?

Drawing a blank at the moment.
