ENGINE OR TRANSMISSION MUST BE REMOVED TO COMPLETE THIS PROCEDURE.

[@kevinwhitt6855]

How many hours does It take you to do one of these drive in to drive out? Thanks for the great videos!

[@iamdjnam]

I can have an engine removed and bolted back in same day. Granted it needs nothing than just this procedure.

[@brdman8667]

With the vice grip idea I used a 6mm Allen wrench for the slots on the opposite side to prevent it from moving in either direction it fits perfect in the slots

[@iamdjnam]

@@brdman8667 great idea

[@brdman8667]

Also with your chain and shackle idea I still used the shackle but instead of the chain I bought a small 3/8 turnbuckle with 2 eyes on either end... still same concept but you can adjust it to what hole you need and it take away all the slop the chain has for it to be more acurate and u don't need to take it off you can put it on either side for both loosening and tightening. The eye on the sprocket side fits in between the shackle and the gear perfect. I'd imagine the turnbuckle with a hook on either end would work as well

[@deadpossum100]

Honestly these videos are great. No fat, all meat.

[@rporobotjack3683]

I'm impressed !. It is so nice to see young men who have learned how to do repairs on vehicles not just being parts replacers. I learned my skills out of necessity , because I could not afford to have someone else to do the work. Shop manuals and the right tools are needed and they last forever. Keep learning and there will be very little that you will not tackle.

Great video man! I have a ton of mechanical experience and a pretty well stocked garage, but I’m still dreading this job. This vid makes me feel quite a bit better. Thanks.

Aman brother! Now that's skill for a young person as yourself, I've learned something new. Thanks

[@MrCam88]

You the man! Best and straight forward on your video. Saved me from buying a new motor 👏🏼

[@in3darts]

I have a 2001 Sport Trac I bought new in 2001 and drove it until 2012 when the cassettes broke with the same motor. I loved the truck so much, I parked it so I could eventually restore it. I prepped in late 2019 to do the work in 2020, but then the pandemic arrived and that pretty much destroyed the plans. But I'm ready now. The truck is in great shape. I dropped and cleaned out the fuel tank last year, put in a new fuel pump and it started back up, but the rattle is still there. I'm not a professional mechanic, but I'm competent and tackled difficult jobs like this before and there's lots of great how-to videos on how to pull and do this task. I have friends who run garages and called them this week. They said basically get a new motor and don't go through the hassle, yet another friend who was a mechanic all his life (retired now) said it can be done and to go slow. This video helps and I appreciate the insight. I sat on getting this fixed for too long and also have to replace the cab body mounts which crumbled over the years. I'm sure there's other issues to resolve, but the truck is worth saving. So, I'm hoping to get started soon! I was also quoted around $700 back in 2019, but now they say no. Hmm.

[@iamdjnam]

Do the work yourself. If the engine ran great but rattled, get yourself a nice Melling timing kit, new gaskets, and go for it!

[@briteidea08]

Your videos on the 4.0 SOHC engine are priceless!! Outstanding!!! Keep up the great work!

[@briteidea08]

@@iamdjnam You’re very welcome. Have a small rattle on my 2011 4.0 at start up. But I’m not sure if it’s the chains. Or because I let it sit for a week or two at a time. Eventually I’ll pull or pay someone to do this either way.

[@nofortunatesonII]

If you let it sit that long between start ups maybe it is just the oil pressure bleeding off? Especially since the noise goes away. You could always put a pre-oiler kit on it like drag race engines use to pre-lube the engine before start up.

[@iamdjnam]

@nofortunatesonII I had a pre oiler on mine for years. Just recently took it off. If you use good oil like amsoil you don’t even need one. Regular maintenance will extend the life of this engine.

[@janevaldez1523]

@@jonathanbox3033 - The story of the Ford 6.0L Powerstroke diesel engine made by Navistar/International Harvester, that succeeded the 7.3, is the stuff of Ford as trash legend. While every poor sucker who bought anything with a 6.0L Powerstorke from 2001-2006 (F250, 350, Excursion..etc) suffered, the Ambulance companies that bought this POS for their fleets really suffered. It is the advertising budget of Ford that is the basis for their appeal. I feel bad for Ford owners, especially those who today are running Fords new 3 cylinder with 5 turbo's (sarcasm)... having said all of that, I'm glad that we have @Platinum Garage to bring the 4.0 SOHC into a usable condition.

Ok sorry I've read some of the previous comments about the broken pieces being removed by removing the bottom steel oil pan which is fairly simple. But shouldn't the upper pan(not sure thats what its called) also ?

[@iamdjnam]

You don’t have to remove the upper. 9/10 times it all ends up in the sheet metal lower. And even if there is one little piece left it won’t make a difference. As you can see in this video, the cassette was still intact but disconnected at the pivot. There was no need to pull the pan. If you remove the valve cover and see the guide is totally gone, pull the pan.

The engine can run anywhere from a month to a few years. It really is all about luck. The broken pieces end up in the oil pan. Occasionally they will get stuck in the pickup tube and starve the engine of oil.

Any way you can help with replacing the front side chains? There’s 3 😳

[@iamdjnam]

If you look at my full rebuild video, that covers all 4 assuming you have the tool kit. I’m waiting for a donor engine to come in so I can make a video on how to do all without the special tools.

I'm removing my motor how do I disconnect motor from manual tranny

[@devanwardlow4379]

Index marking the cam gear to the cam and the chain to the cam gear helps too, that way you can make sure it goes back exactly the way it was b4 breaking bolts loose. O and ive done extensive research on timing drive kits for the 4.0 mostly cuz i was looking for a performance kit or a kit thas better then the ford one. Out of all my extensive research i have not found 1 afternarket kit that can even come close to matching the quality of the Ford kit which is far superior in quality and design. I know your saying they look the same but theyre not.

[@iamdjnam]

I know all about the chemical compounds in nylon timing cassettes. Yes the Ford is superior. No, people don’t wanna drop 500+ on a oem kit for a 20yo vehicle. The Melling is the second best kit, followed by preferred components. You can read and read and read but the best research is done by experiencing it first hand. I’ve tried every guide on the market.

[@mikemaj8467]

Actually there's quite a bit of documentation online about aftermarket tensioners failing. I can send links if interested. Some of the aftermarket components have thinner rib structure which will deflect more failing sooner. I am on a budget as well but, IMO this job is too labor intensive to take chances with aftermarket parts and too risky to to not change other related timing components at the same time. Even if it buys someone time until they sell the car after repairing, it becomes someone else's problem 5000 miles later.

@@mikemaj8467 If you look closely, you’ll see that Melling parts are actually manufactured by Borg Warner. The transfer cases on the explorers are Borg Warner. The chains say made in Italy which is as good as you can get. Definitely worth getting the melling kit.

No plastic guid without metal frame can last long! I just found out that the ford guid broke after 40K KM when I was replacing valve stem seal, but I thing it still can do it’s job for a long time before it is completely gone and then the rattle will be heard. I will seal the top of the guid with JB weld to prevent it drop down from the upper bolt. What a fatal design!

[@iamdjnam]

Yes! Like my other video!

[@chrissanders2562]

How do you time the cam when its jumped timing? Edit: oh it makes sense nevermind 😅

[@josees1977]

Same procedure for a 4.0 mustang engine?

[@iamdjnam]

Yes

[@karlklassen603]

Man..thats good help!.. was wondering how do you changeout the back chain and sprocket?

[@iamdjnam]

Only changed the top sprocket. You can’t change the bottom without removing the jackshaft plug and buying a new special Ford bolt.

[@jasonbennett7050]

@@iamdjnam what keeps the chain on in the bottom when you remove the gear

[@iamdjnam]

You got the lower jackshaft sprocket and TTY bolt. You can’t remove them without removing the rear plug cracking loose the 8mm head bolt.

[@jasonbennett7050]

@@iamdjnam so the chain wont just fall off the lower

[@iamdjnam]

Nope it’ll stay on. No chance of it falling off whatsoever.

Hi, I see there are conflicting reports over the internet on whether the 4lt V6 is an interference engine or not. Also seems there are two types. Mine is a 2005. Interference or not ? thanks.

[@iamdjnam]

Every 4.0 SOHC ever made is an interference engine. If you click on my channel and go to community, you will see the picture I have up of all the valves bent.

[@chasermalloy7406]

@@iamdjnam Ok - thanks for reply. Seems you can't rely on some of these sites that supposedly identify engines to be one or the other. Several identify the 4 lt V6 as non interference. Thanks again cheers
