Ray, How did those Freeze plugs look that had rust on them?

love project jeep!

It is a good thing this gentleman is skinny. What contortions a fellow has to go through!

Who makes those extra stubby ratcheting wrenches you use? Those things are the bomb!

Lol that's funny, you said the "enginerds."

WHY ARE YOU WORKING SO HARD ON A FIAT ?

I'm an old wrench turner I worked as a mechanic 60 years , Ray works his way through problems that keeps us , me entertained, click. Thank you for your time and patience learning some new technology to everyone watching click,click.

I see no reason you could not have put in a few of the exhaust bolts (nuts) in before putting in the intake manifold. edit – yep. Watched farther.

Door Trim Tool. I found one on the side of the road about 10 years ago. It is the handiest tool in my tool box. I don't know how I ever got along without one.

Great video project! Love to see old Jeeps get some love. As for the 4.0L, AMC designed and went to production in 26 months. Just in time to be released in September of 1986 fo rthe '87 model year, much to the chagrin of Chrysler execs. Even though Chrysler execs had the purchase of AMC in the bag, prior to their actual takeover in January '87, they decreed the AMC 258 shall not be installed into the XJ platform even under the cries of customers demanding better power with a six. But AMC got around the order with the 4.0L borrowing some of the design cues from the 258. The XJ/MJ was designed for a V6, hence the short hood design but the absolute dog of GM, the 2.8L was what they could get by the 1984 debut instead of anything else. Fast forward to 5 million 4.0L engines made and more stringent upcoming emissions standards for 2007. Chrysler would not spend money to make it emissions compliant and thus the '06 model year was the last. They chose instead to install an engine from the minivan line into the new plastic JK Wrangler until their own Pentastar design was available.
.
For those not in-the-know, you can use the 258 crank and rods with the stock 4.0L pistons and come out with a 4.5L with no other mods required. In terms of intake manifolds, both 'Log" and "Horseshoe" flow fairly equally despite the myth about the "Horseshoe" style intake being "a lot" better. In terms of the "best" head? The 7120 (lacking provision for the block's head locating dowel pins) or the 0630 (with the dowel pin locator holes) are the best flowing factory heads. Both heads will work on all 4.0L blocks. Only the raising roof of the exhaust port increases flow and in the case of the infamous 0331 smog head casting, was raised but over all made with a smaller cross-section to control emissions and still keep the engine legal without an EGR (which was deleted from the '91 and later using the Chrysler SBEC-II ECU).

Love all your videos mate.

Would wrapping the exhaust help mitigate issues that having the manifolds on the same side prevent?

Ray that intake and exhaust closed to each other is to heat up in cold starting, they design that way like old carburetor electric choke

The rectangle ports are the intake toe round ports are the exhaust you said the opposite

I've found a reason for me

To change who I used to be

A reason to start over new

And the reason is you

And the owner of this Jeep is : R a y ! 😂😂

The 4 liter straight 6 engine was great other than being a real gas guzzler, it had amazing power and torque, something that the 2015 V6 in my Rubicon unlimited doesn't have. From my experience the Straight 6 was the best engine Jeep had other than perhaps the 390ci V8 American Motors engine that came by special order back in the 1970's.( If my memory is correct)

Sometimes I miss my '70 Grand Prix with 400 cu in V8. A few bolts and hoses, the radiator and fan were out and I could stand on the ground in the engine compartment changing the timing belt and gears, or whatever was needed in there. I think all cars then were required to have a hidden secret bolt on the water pump.

Working through an 82 Z28, an 88 and 94 Ford Explorers, 2007 Honda Accord kept getting tighter and tighter. Plus the thrill of buying all new metrics. Went through the same tool additions at work when we switched from Boeing to Airbus.
Finally a 2022 RAV 4 Hybrid with the bells and whistles, and I can spot the oil filler, air filters, and fuse box.;
I'm waiting for you to dig into one of them before I dare to start ripping and tearing.

Love your channel, don't let the trolls grab ya from under the interweb basement stair bridges where they hide from their moms and pass judgement.

After 40 years aviation tech on USMC F-4s, De Havilland Herons,; Cessnas, to Boeings, 737- 200,300,400; 727-100,-200 757; 767; 777; Fokkers, Japaneese YS-11's, McDonnel Douglas DC9, DC10 We've learned to adapt. go by the book when that part should be there, but eng decided it would be harder to get to hidden elsewhere. (It fits perfect on the drawing).
Occasionally we find the golden part that most of the entire Aircraft is built around, and we gotta change it .Keep pulling stuff loose 'till it falls off. Fun times with commercial aviation.

You have YOURSELF a great day, and we'll be waiting for the next gravity drop. If the members haven't worn it out yet.

😈✈🛩🪂

Next investment should be a top side creeper

I thought this is a cooking channel ,,smokem if you brought em.

Rusty ? 😂 Only a Floridian would call those rust free bolts “rusty”.

"jeep dirt" careful how much of that you lose…. could be all that's holding it together haha!

Ray, you are entertaining and awesome to watch. I work for myself, I hate to tell you this but when you work for yourself there is no after hours. It's just a longer day than usual. 😜
When I went to work for myself I told my old boss if I work as hard for myself as I do for you I can't help but succeed. I did and it's obvious that you will too. Congratulations on being your own Boss.
You are literally doing everything on this Jeep, are you sure it's not yours?

My understanding is that the hot tip on these 4.0's was to install the fuel injection from a GM 4.3 liter V6.

The 4.0 got a tubular header from the factory on the YJ and XJ, they always crack where the pipes come together, that was an OEM header you pulled off.

Lucky you didn't have to grind anything off the exhaust header flange to clear the power steering pump brackets. Some aftermarket headers have that issue.
