I friend of mine picked up a wj with the 4.0 for a trail rig build 212k on the odometer. We pulled the head off and pressure washed it lol. That was about 20k miles ago still going strong 👍
I know this videos a little old but did you see your oil pressure pick up a little at idle after this? If that was my head I would drain the oil and fill with ATF and let it idle for 10 to 15 mins then drain it out, should clean up alot of the gunk you couldn't get with the shop vac.
Sea Foam about a week before you oil change, over time will clean up messes like this. I also use high mileage Sea Foam in my fuel every couple of fill ups. Stuff works for me...BTW, I change oil about every 3000ish miles. Hope it helps. God bless, stay well.
With these engines just cover the intake inlet and use air and a screwdriver to clean it. A vacuum works really good at first but you will muck it up. Spray it, brush it, blow it. Then change the oil and filter. It'll be fine.
Make sure You change the CCV valve system when you do the valve cover job, these get plugged or restricted and will cause the sludge problem. Should replace them every 4th oil change or so.
Clean asf damn good sign something may be wrong. They cleaned it before selling. Those rocker arms have been replaced. The holes are not center. Not spitting out oil correctly
Ford filter also fits. Larger, with more capacity. From naxja forum.. It is a Ford V8 oil filter. For Mobil it is the M1-301 filter. For Motorcraft it is the FL-1A filter
5:50 made me think about a visit to the dentist where a fine stream of liquid is squirted on the teeth and gums while a strong suction device simultaneously removes it.
There is only one way this comes about some one is not changing the OIL is the compression is good one can do a good sludge treatment on the thing pull the pan and that is probably leaking also and replace the oil pump and bearings this can give some life back to this motor for a few years this can be done for less then 500 dollars the other way to go is to replace the motor for about 3000 dollars i have known of 4.0 doing 400k
Small dealers who then hurt good people by dropping these lemons on them. Until they finally run out of luck and drop one on a guy who doesn’t mind going back to prison.

bro i respect you for doing all that jazz. If this was me in taking the damn head off and pressure washing it

It is a Ford V8 oil filter.
For Mobil it is the M1-301 filter.
For Motorcraft it is the FL-1A filter
Good info, 👍 , much appreciated
A few regular oil changes with filter of course. Will clean that up
Can also empty 1qt oil out replacing it with 1qt transmission fluid.. run it a couple miles change and repeat.
Looks like time for some BG cleaner, not cheep but, works.
Dude thats clean af. Pulled cover minne today and its a friggin mess in there… so now imma tear it apart and deep clean whole motor instead….
I'm having a hard time getting the bolt in the back of the valve cover I didn't see how u got to it seems like my rachet won't line up with the bolt
I use flex head ratchets
Trans fluidand seafoam for the next couple oil changes
When I changed the VCG on my 75 258, the valves were clean...
So is that from not changing the oil??
Probably cheap oil,

Yeaaahhh. You got Common Kings in the back 🤙🏽🤙🏽🤙🏽🤙🏽

That orange oil filter sure ain't helping any....
I really need to look into this Fram Filter thing. Hmm.
Paper mediums offer superior filtration.
And it sure ain't hurting anything either.

Great video
Would seafoam clear that up some?

i have known of 4.0 doing 400k
Mines at 230 never done major repairs. Bout to do gaskets tho so I can go camping and duning
Would you say this Jeep is still dependable/reliable?
These jeeps don't die
Yes they do. Ask me how I know
@@highwayxj9397 how do you know?
@@vicb825 it died
@@highwayxj9397😂
Does it run any quieter after cleaning that top end up a bit?
Nope.
@@Donnythelatemodeltech lmaooooo
I had sludge like that in my ‘88 camaro lol
Love the morning videos 🔥🔥
Thanks, next one should be entertaining, I hope.
What causes this? I see this on YT and Ticktock- but I've never seen it IRL. Just people not changing their oils or what?
Pretty sure the heads on these things are the reason. Combined with the Quaility of oil used for the extremely high miles these things usually have.
when he says 'at work we just get rid of these cars' does that mean they just get dumped on the next trusting person who gets the problem
They get auctioned off to small dealers

Change rockers and rods.
👍
2011 jeep Cherokee, water pump, gasket leak and temperature had to be replaced and I’m not a mechanic $1,600 to repair sucks
Better become a mechanic because that's easy peasy stuff
I dont understand how ppl let it gunk like that.
Me either. The easiest and most important thing to do is change the oil.
Well done on the video, but you should be ashamed to reassemble that engine with that kind of neglect.
I'm more concerned about the "at work we usually just get rid of these right away comment". Hopefully meant send them to scrap yard.
Thats what my 91 cherokee looks what do
Time for some MMO.
🤘
You should have put it back together and run an engine cleaner. I change my oil twice a year, my engine is totally clean.
