Disassembling our crusty Chevy “Stovebolt 6” engine project | Redline Update #25


– All right, as you can see, the other day we got the
216 out of the pickup truck. We did a little bit of cleanup work, basically trying to get access
to a lot of bolts on that. We didn’t take a ton of time, we probably could’ve taken
a power washer and such. We did hope that we could see a little more of the paint and such. Really all we can make out at this point is it appears that the
bell housing on this may have been painted some sort of red. The block, what paint it did have on it appears to be maybe a silver color, and the the tin looks like black based on, like, right here. Looks like the valve cover
and the side cover was black. And then you can just
make out Thriftmaster here across the side of the valve cover. So with that, my next task is to get this bell housing off, and get it on the engine stand, and then just stripping it down for all the parts that we can reuse, and we’ll go from there. (upbeat music) So this mechanism across the back, I should have showed you
before I took it off, but any rate, what it amounts to is this is the starter
button on the bottom of the, you know, inside the cab, where I had Ben, I told him to hit the starter, and there’s physically a
plunger that he pushes, and when that pushes down here, this actuates all this mechanism. And then there’s a lever
arm on stop of the starter, and that is the solenoid, solenoid in the sense
that it just actuates, or makes the contact from the positive wire through the motor. (wrench clicking) (drill whirring) (hammer thudding) (wrench clicking) On this intake and exhaust setup, you have a separate intake, and
a separate exhaust manifold, but they’re held down by a common bolt, so there isn’t an individual. So actually, here, initially it looks like this may be broken off, it
may be just a dowel pin, I don’t know until I get there, again, I’ve never had these apart. This is actually pretty typical, even into Jeep four liters of the ’90s. The idea is use this clamp, as you pull this tight,
it’s pushing the exhaust and the intake, creating that clamp load. Let’s just call it an oversized washer. But I’m gonna heat in the head area here, (fire roaring) here, in all what’s
there, one, two, three, four, five, six bolts. Heat up that area, it’ll
just help get things loose. And I’m either gonna have to do it now, or I’ll have to do it later, I might as well do it now
on the initial teardown. (upbeat music) So this motor has,
according to the odometer, 54,000 miles on it, which,
quite honestly, I can believe. Of course the oil specs of those days was not consistent, wasn’t
certainly as good as it is today, so you get any kind of heat
buildup, it would cook the oil, and of course you get all this baked on oil and sludginess. So progress-wise, our head is off, valve train is out, oil pan is off, timing cover obviously is off, we’re at the point where we
wanna pull the camshaft out. And of course the lifters are
stuck partway in the hole, I got some of them out. And now I’m really trying to figure out how this oil pump comes
out quite honestly, it’s pretty interesting little setup. My understanding is whenever you have these little catches on the
bottom of the main rods, is that that’s actually scooping oil, and that’s how the rod gets oiled. Now, these were never engines
that saw a lot of RPM, so low RPM, no big deal. Very similar in fashion to,
like, a Briggs & Stratton motor that we currently use, they have a little, what they call a dipper. So that’s where we’re at on this. There has been a little head
scratching to figure this out, I’ve never done one of
theses, as mentioned. And I probably shouldn’t
tell everybody that as I’ll blow my cover, but I gotta be honest. All right, so we’re gonna
keep working on this, see where we get. Idea is today we want this completely, completely tore down, and off to the machine shop. (upbeat music)

  1. I have a 250 straight 6 in my 78 GMC 1/2 ton 4 speed 4×4. I don't care how popular LS swaps are, I'm leaving the 6 in it. What it lacks in power it makes up in torque, it might only get 8 mpg but it's never let me down and starts right up after sitting for 3 months. I'm 25 and it will probably outlive me

  2. I sure hope that you kept all the brass shims for the rod bearings as it is a learning experience for sure. It was one of my very first tear downs and learned the hard way how to adjust bearing clearances. I must of done something right as that engine went two revolutions of the speedo but it was tired and making some small noise. I checked the bearings out and other than a couple thousands was fine and just removed shimes accordingly so changed rings, and honed cylinders and ran it some more as a stationary engine for sawmill that ran for ten or so years. It was garbage after that. A very strong good engine that they put pressure to the rods later then in 55 changed up that whole series to a one engine fits all and interchanged with the V8 at that point. It was the start of the 235, and so forth. I used a corvette blue streak exhaust (duel) or split commonly called… this is back when we butched cast exhaust manifolds for the duel exhaust sound but then it was a sound of its own. I had the old school plug wires and the "jumpers" so it would increase spark and turn tv's upside down, it was a joke for the most part but they come the closest to burning more oil than gas and you had to tow start or coast off a high hill and with enough gas get it running again. A minister put karo syrup in my gas but it was so worn out it just burnt it and he confessed to me cause it bothered him so bad so I did him the favor of not harassing him any more but of course I was shortly drafted

  3. Yep the oil goes to nozzles to squirt oil at the rods which have scoops and to spray oil up the cylinder for cooling and lubrication. The oil pressure gauge is for show as the pressure is not critical. One oil galley feeds oil up past a rear cylinder head bolt to feed oil to the rockershaft. That is a bad feature and there was a kit available to route the oil outside the head and feed it in through a hole you made in the Valve cover to feed the rocker arms. Many a rocker shaft and valveguide were destroyed. If the oil were changed often with flushes then no problemo. These engines powered 5 ton Trucks so don't laugh . Lots of Torque with that long stroke

  4. neat motor – it's also the motor that was put in Toyota Land Cruisers…. lots of tribal knowledge on that side of the pond because it was used in the FJ40 until 1974, and the 2F motor is quite similar in design (though highly modified too)

  5. Davon those pre 1955 Chevy sixs were called partial pressure lubrication because of the lack of a fully drilled crankshaft for rod bearing lubrication. As I remember from my days as a high school auto shop classes they were good for about 65 mph in stock form but if you pushed on harder that had a tendency to burn a bearing also the fiber cam gear would give up if you were hard on the engine. I remember a friend of mine power shifting a '49 deluxe that only had 36,000 on it and the cam gear sripped out.

  6. Can I make a suggestion? Do some engine videos where you take a used engine and repair whatever prevents it from being a reliable engine and then reinstall it in a truck that has been repaired inexpensively. Do a low-buck clean up of a cool old rig.

  7. To be frank you haven't shown one with a blown engine broken piston or cracked casing etc ! It was entertaining at first.

  8. I just finished swapping a 216 in my 47 Chevy Fleetline for a 235. I know all the things he’s going through. They are very simple engines to work on. The 216 is rated at 90hp with mods you can get more out of it, the 235 starts at 115hp, can go up to 140hp stock in later models.

  9. I realize the making of this video is a lot of work but six minutes !! Anyway, it was great and I really enjoyed it. Thank you!!

  10. Want to see how oil from a long time ago performs? Check out Project Farm from a couple of weeks ago.
    Someone sent him an old unopened can of motor oil. Bunch of tests and such…

  11. Syncing some of his actions with the music was a brilliant move by whoever edits these videos ie: hitting the bellhousing with the hammer, using the ratchet on the bellhousing. You can bet that wasn't an accident.

  12. the same motor I had in my '53 3/4 ton chevy,,, it was the LAST YEAR of the 216 cu in. from that next year on it was just the 235, then the v-8's and then the 292? 262? until the 230-250

  13. I currently own a 51 Chevy style line deluxe with a 235 power glide and have rebuilt the engine so during the rebuilding process if there’s any questions let me know!

  14. I doubt that thing even had a by-pass oil filter.
    Please let us know what gets lubed by the pump.
    6:02– Interesting chamber; lots of quench.

  15. Так приятно видеть как из старого двигателя превращается в новый молодцы все грамотно класс)

  16. Awesome video !Always really enjoy your videos . I have been assembling a 1940 strait 8 Buick . It came to me partially disassembled . Sometimes that is a bad thing . I had the engine completely assembled and installed the bell housing . When I tried to install the flywheel it would not go in the bell housing any way I tried . So I began digging for information . I knew that you had to install the flywheel bolts into the crankshaft before you installed the rear main cap . ( The bolt goes through the back of the crankshaft then the flywheel with a lock nut on the flywheel side ) You also have to install the bell housing then the flywheel and the the bolts . After all of that you install the rear main cap . I had to back way up to fix my boo boo . I hate it when others tear an engine down !

  17. Another great video Hagerty, feels like I am right there. The Dipper Stovebolts motors were the same from the beginning until I think in 54 when Chevy finally produced a full pressure version. I am really enjoying this vid, thank you.

  18. That old scoop system for oiling the rods didn't do so well in grain farm country of Eastern Washington where they drove a lot of steep hills. Rod bearings would go dry while going up or down steep hills. My dad's friend had a 1948 2 ton truck with the oil scoop 216. He updated to the more modern 1954 235 that operated on lube from the oil pump.

  19. I hope y'all know about "targeting" the Pan. Two of the timing cover bolts are in the inside . Remove them after the pan is off.

  20. I am really excited about this project. My father had a '50 Chevy 3600 and I got pics to prove it:). Thanks for posting this update and happy holidays.

  21. I had one in the 70's in a 62 panel truck. I think it was a 230 with an automatic 2 speed. That truck ran and ran for years without doing anything to it. Nice to see the guts of those work horses. Thanks for the video.

  22. I have a 51 4400 with the 216, I don't think it's ever been apart. The truck is original except for an old paint job that was probably put on 30 years ago. She runs like a top though, doesn't stop because she needs a master cylinder and brake lines. I've been at it for a year, the parts list keeps getting higher and higher. I'm not making her a show truck; just operational so I can get gravel for my driveway, wood for projects, move brush and firewood, and of course to put a smile on my face.

  23. The 2i6 "splash oil system" was the standard engine through 1954 and became the 235 in 1955.The 235 "full pressurized" engine was used in the 1953 and '54 powerglide automatics only. In 1955 all Chev stovebolts were 235's. They also had hydraulic lifters while the 216 had solid lifters. You need to pay special attention to the oil pan in your 216. It has oil nozzles located on the outer rim inside the pan that are aimed at those oil pick-ups on the rod caps. These were bent to hit the oil caps by use of a factory made template that fit over the oil pan and you then hooked up pressurized water to the nozzles to help you tweek them accurately.

  24. Super cool Davin. Tearing down a piece of history and opening up a window to see how engineering and manufacturing used to be done 👍

  25. I've always been partial to the straight 6. I had 3 or 4 Ford trucks with the I6, and my dad had a couple of Chevy's with the i6 engine, whatever it was. They were all pretty good.

  26. Hey so what would you guys recommend for a engine break in? I saw on the Buick nail head you guys kinda let it run on the stand but I was told by a few people to have it in the car and get some load on it to break it in and various rpms. You guys rock!

  27. It was great to see more of the time lapse production rig at 6:30. I’d love to see a bit more behind the scenes from a production and filming stand point. It is why Hagerty’s videos are so great.

  28. You could do with a 'dead blow' hammer in your tool kit rather than using a ball pein hammer to shock parts off.
    One of my favourite tools.

  29. complete it before christmas and shoot a video of transporting a christmass tree at the back to end the year

  30. Always a subject of discussion and dis-agreement. Please confer with your machinist of choice regarding the conversion of one of these solid lifter antiques over to hydraulic lifters??? Would love to hear a "expert/experienced" opinion/answer along with the logic behind that answer.

  31. Where do you find a machine shop that will work on old engines like that. A few years ago I tore down an old Ford flathead. I had to drop the project because I couldn’t find a shop the bore the cylinders.

  32. Those are Pins (front and rear) on the exhaust manifold, and for the distributor, the whole thing turns to advance, when running.

  33. There is still a couple of 235s buried in my brothers back yard.
    216s didn’t have very many main bearings. Wow, that actually has oil dippers on the rods.
    I think that has 4 main bearings where 235 has 5 if I’m not mistaken. 230, and 250 from the sixties had 7. One on each side of each rod, those things were good for 10,000 rpm which some racers did with them.
    That bell housing looks like the same for 55 Chevy.
    Modern cars have electric solenoid pulling the starter in gear, on them oldies you pushed it in gear with your foot. That’s getting pretty rustic.

  34. Most dependable motor ever made, I actually have one in a golf course tractor, it drinks gas, but its start every time and runs forever, a monkey could work on it.
