It's all coming together on our 1993 Jeep XJ 4.0L engine. We've done the math, done the machining, ordered all the parts we need, and restored what we didn't need. There are no excuses left, it's time to start putting things back together. As always though things rarely go as smoothly as you'd like, but that's no surprise to Davin. He's ready to problem solve and get this Jeep back on the road.

*DAVIN!* These episodes are too dang short anymore, man. I know there's all sorts of guides and algorithms and such advising channels on how long to make episodic content on YT and all, but these just feel rushed and short anymore. *This is the best show on Hagerty* , not to mention on YT in general - how about some more of it? Thanks, - Ed on the Ridge

Hey Hagerty - the walls of the garage (assembly room) look a little bare. Maybe have your graphic folks look back in the image archives and find some memorable RedLine Rebuild cars and have them printed in large format and create some Hagerty Art for the shop walls. Like a historical reference of the previous shop work. Maybe swap in new images based on popularity of the videos. Even simple images of the shop truck would be cool. Maybe a large oversized print of Tom Cotters smiling face...? A Cotter photo would be super funny even if it was just put up for when he visits.

FYI, the 4.2L predates the 4.0L by a lot of years. The 4.2L, then known as the 258, debuted in 1970.

@Sundancer268 2 года назад

When I was a kid back in the early 60s, I use to help my dad when he rebuilt the old 225 Slant Six and the old 292 Y-Block and he had a large can he poured a quart of oil into and he placed the piston into it so the Wrist Pin and Rings were well oiled while he was installing the previous soaked piston. I have done that with every engine I re-built/refreshed since then from old lawn mower engines to the 392 I installed into my 75 Scout II.

@williamwinsor7376 2 года назад

That’s how my dad taught me. I treated my stuff with respect because I had to earn my things and burning rubber standing in one spot wasting rubber I just hate that but I love ground pounding torque.

@thatguyontheright1 2 года назад

I need one of those washers. I guess when I get to building my 4.7L to put into my Eagle, I'll go into cad and have someone I make it. The reason why the AMC 4.2L crank snout is longer is because the V belt pully and harmonic balancer set up was much thicker.

Actually the Teflon tape/dope is not a sealant. It is a lubricant to allow better seating and removal of the threads

@erichildreth7562 2 года назад

This is coming along great!! Can't wait to see the whole thing all together! Great video!!

@bowez9 2 года назад

With brass PTFE isn't needed with Steel PTFE is needed (due to friction between the threads). Friction lower with brass so they can be tightened sufficiently to full seal without sealant, but it won't hurt.

@ronnieboucherthecrystalcraftsm Год назад

your way with the washer is mechanically correct -

@CanadaBud23 2 года назад

Later 8w cranks have short snouts. The longer snouts need machining or a spacer. Most kits come with that part included but if you piece together a motor with a long snout you have to remember what crank you have so you don't run into that problem. Not hard to fix though. Apparently early and later 8W cranks are short I think back to 1980 I think but earlier than that may have been long depending on the belt drive and vehicle. After '80 4W cranks have the long snout, need a spacer. Mines an '89 4W, I used a machined spacer.

@skylinefever 2 года назад

Yes, I think Hesco sells that spacer for those that need one.

@crxtodd16 2 года назад

Outstanding work as usual! I don't know about you, but I HATE using those types of ring compressors. Even so, you made it all look easy. Anyway, I really like the black, brass, and silver contrasts you got going on there as well. Looking solid.

@RANDOMNATION907 2 года назад

Gotta write that one down. Use a piece from the old balancer as a spacer.

@robertmaxwell3548 8 месяцев назад

Nice Build.

@Ikillintel1 Год назад

8:21 they added that 1/4 inch because the 4.2L has V-belts and for two V-belts you need more than one rib, so covering the damper on the 4.2L is another V-belt pulley that slides on and is secured with a key of its own on the crankshaft and that washer & bolt. Thus the need for people building strokers to have that snout trimmed aka a nose job 😅. Hope that helps

@beachboardfan9544 2 года назад

Awww man, wonder how much power all that extra weight on the end of the crankshaft cost.

@skylinefever 2 года назад

I think your last video featured a Delta cam. Do you know the grind number or the specifications? Your situation happened because there is more than one type of 4.2 crank. One used a V-belt, one used a serpentine belt. The serpentine belt crank is what accepts the 4.0L crank pulley without a problem. Hesco sells the spacer.

@jakobv8 2 года назад

Hi Davin. I love your videos and have watched every single one of them. I don't believe you do requests, but I am going to ask you anyway. How about you pick up a Nortstar with a blown head gasket/pulled stud next time? There are so many of them around, dirt cheap, cool cars. I just bought one, so I ought to know :-)

@HomebrewHorsepower 2 года назад

When I did this I had the end of the crank snout shortened so I didn't have to worry about a spacer.

@mpezzi 2 года назад

Idk who thinks you don't need a sealant on pipe threads. When I assemble pneumatics, I have to use sealant or it will leak immediately.

@OMCbuilt 2 года назад

@2:55 Tape and Dope/Joint compound should not be thought of as interchangeable. Tape is more of a lubricant than a sealant. It cuts down on the friction in the threads allowing you to get an item (like an NPT threaded plug) tighter with the same torque. I would never use only tape to seal any liquid under pressure. Thoughts on this from other people with plumbing experience?

@brarautorepairs 2 года назад

Are the threads tapered? If not then use Teflon tape if you are really worried. You are correct about the torque values changing with a lubricant but I don't think it matters in this POS application. It is a dumb engine anyhow. The tolerances are massive.

@moparedtn 2 года назад

@@brarautorepairs That "dumb engine" is one of the most, if not THE most, durable gasoline engines ever made. 50 years of history prove that out; the AMC/Jeep inline 6 is universally famous for that. Tolerances, as Davin is pointing out in this very series, is about industry standard for the time it was in production. Further, there's no less than *7* main bearings in the bottom end! It's a virtually indestructible engine with minimum maintenance, much like the old Chrysler Slant 6. P.S. Those threads Davin was plugging are NPT thread ("pipe thread"), which is why they're tapered. Using a tapered NPT thread plug, along with a few wraps of *good* teflon tape (no Chinesium!) and they will never leak - and be easily removable in the future. - Ed on the Ridge

@moparedtn 2 года назад

As someone who's been in the fire sprinkler trade for over 40 years now, the stuff we work on has to be good for at least 175psi - far more than anything on an engine. I've never used anything more than good USA-made teflon tape on all threaded connections.... and I never have leaks (the boys that insist on using "dope" or dope/tape, well, they have leaks). You either know what you're doing or you don't... Regards from a long-time "glorified plumber", - Ed on the Ridge

@brarautorepairs 2 года назад

@@moparedtn Durability wise, it is well known that Lexus/Toyota have made some of the most durable and reliable engines in the world (i.e. LS400). If you look at Ward's best engine list, you will hardly see any Mopar products until 1999 and those entries are few and far between. This straight 6 OHV design is so basic that it doesn't belong in anything made in the last 20 years. When the Internal combustion engine is finally retired, this engine will be near the bottom of the list beside Lada.

The best build for the 6 is to take an old 252 carb engine and put the 4.0 FI head on it. It's pretty easy to do plus you get 250+ hp, just bolting it on with a couple of small mods. The wiring is the worst part
