I been running my shop since 1980 and only seen a handful of any TH-cam videos and yours is the best because of you are doing a excellent job in every aspect from cleaning surfaces, bolts, and are just naturally a good mechanic which is rare. Good job explaining everything and having the patience.
Thank you!
@@Bryan916 4 years later and your work is still valued. Thank you, sir.
@@Sk3wd33 Thanks Brother I appreciate that very much!
@@Bryan916dope channel man new sub! 🫡 question for u: if I’m changing my pcv hose from my 07 jgc Laredo 3.7 cause it has a leak from left side of the elbows (p0507) is it as easy as plug and play for the pcv hose to replace?
@@Sk3wd33that’s your jeep in the video?
Bryan..your a great person for recording this!! We need more people like you !!
Watching this in 2024 thank you bro was lost af when I started
Best step by step instructions I've watched on my 4.7 Ram
the Baggie idea works like a charm. I use to do that when i was a Technician. Also i use an egg carton for spark plugs to keep them in order. I have always known it as a firewall.
You sir are a beast. Im 25 from ri. Last day of tech school is this monday. I been worki g part time at a vw dealer as express tech. Ill be full time on tuesday. You motivate me to become better. Gotta keep working hard to get to that next level
Hey Brian thanks for part 2 ,i have followed your tutorial and removed both heads on my 4.7 without removing front the cover as i dont have a rattle gun yet and found 3 seats stuck to the valves. the pistons are good and the head gasket shows no signs of breakage. As i live in New Zealand parts for jeeps are expensive so i will go to machine shop and see what they can do. Your instructions have really helped me to tackle this project with confidence i have a manual to refer to but your videos allow me to see how its done so thanks again for your videos .
I appreciate the positive feedback brother and glad this video helped. Shout-out to New Zealand!
Just about to start doing head gaskets on my 2002 Ram, this will help heaps, thank you from the UK
Thankyou for putting this video up Bryan. You've already helped me no end.
I like to listen to music of the era of the car that I’m working on.
1999 jeep: 90s music
1985 ford: 80s music
🎶 📻
This is by far one of the best videos. Thanks.
Those water pump and timing cover bolts are all different lengths for guys like me who can’t keep track of things.
Easier to leave them where they go as you take them out. Just orient them loose, in their original positions.
(Or mark them with a paint marker 👌🏼)
Just found this video. I'm searching because I'm about to tear into the engine. Hopefully, I can fix it up. This is a great teardown video.
Extremely thorough procedural work. This video has made one person very very happy today. Thank you.
Uhh not really. He was just in it to take the customers money. He knows damn will that if a valve seat came off the engine is blown.
I did this about 2 months ago to my 04 with the help of this video. After a 1000 miles I can comment on a couple things. First the "waterfall" sound from the heater core is gone. Second I found the hard way to use genuine Mopar parts, at least the tensioners. I used aftermarket ones and had to change them out after a month the chains rattled so loud at cold start. I knew it was the chains seeing I put solid lash followers in place of the hyd ones and they make a distinctly different sound. Putting Mopar tensioners in quieted it down significantly on cold start, no chain slap at all. Still get a little lifter tick but as the engine warms it goes away and I will say the solids definitely helped performance at the top end.
Just finished one this week,bought the full head gasket set for 35 bucks on eBay.
I'm in the process of doing this on my 2002 Dodge RAM 1500. Thank you for the video. You've been really helpful.
No problem 👍
Called Heads Only to inquire about my heads and their price is better than I've seen anywhere. I gave them your info and told them you recommended them and to check out your great video series. I told them to they need to hook you up for your shout out to them! Thanks for an awesome tutorial!
Thanks Brother I appreciate that!
Absolutely incredible. What talent! Thank you for posting.
I am tearing off the heads on my jeep I wish that you would’ve shown how to set the timing before you toured apart
You are one bad ass mechanic!
I have worked on most anything that moves you do an amazing job. Bulkhead comes from the aerospace industry. Its a position that blocks off an area from another and has connection points that allows for throughfare of electrical, control components and hydraulics. The maintenance world is starting to come up with more common phrases across the board. Heavy equipment world has been using bulkhead for a while now as well. Just a matter of time before the automotive industry adopted it.
Great video every second of it. You have every detail. Thank you
just found this vid because i have water in oil pan, head gaskets or warped head. great job thanks
wow - - great video - thank you.... big job....for sure.
Well done sir! Waaaay past my expertise level or skill set but really really informative and educational.
Love your content! Great to see you are putting more videos out. Hope to see more in the future
To prevent the valve dropping many don’t have properly bled cooling systems. That pocket of hot air in the system creates to fast of a change in temperature between the aluminum head and the cast iron block then poof valve dropped. Same thing happens on the 5.7L Hemi
I swear this guy is good...love watching his channel & BTW I love Harbor Freight, not all of my tools are from there,but best believe they keep money in my pocket & in the bank.
Such a cool talent to have.
Thanks for these videos you did a great job so glad you talked us trough it will be watching the rest of them for sure
Bryan thank you for the video what a GREAT job. Yes you need a headset for the video. I am half way into the project this gave me allot of information. Thank you for telling me about Harbor Freight impact.
This man has some serious skills...
Seems like replacing the engine with a rebuild would be quicker and guarantee perfection. Might be a bit more costly depending mostly on what the mechanic charges.
This is where I'm currently at. I didn't drop a seat. I did an inverted water leak test.
In under 10 minutes the water leaked out. I'm thinking I would try and grind them back into seat. Compression was:
#7 155 lbs
#5 150 lbs.
#3 140 lbs
#1 40 lbs.
Thank God it didn't leak though the filler cap! I've got a lot more problems than this!!
Really like your work, and explainations.
This video was very helpful. I appreciate you making it. Thank you
Such an informative video and I'm only halfway through, thanks man. Tearing off the heads on my 01 grand cherokee in the coming days/weeks in my free time.
I've had a rocker arm come off on my dodge. It's pretty common actually. It happens from not changing the oil when you should. The valve lash adjusters get gunked up. You can either replace them or take them apart and clean them real well. I took mine apart and cleaned them up. And started changing my oil more often lol. Haven't had a problem since.
All my respects for you bud
thanks
Love your content as well, 100% helpful You kind of sound like that guy Carl From the Movie slingblade ! keep up the good work
Good work so far Bryan.
Good work. Like the long vids...its firewall BTW
great job customer gettin their money worth, gonna use the vicegrip on cam technique
Thank you sir!! Appreciate you making the video! Power Director is the editor I use, it's free too
Awesome video, I appreciate the step by step... I just started tearing into my GC.... came to a dead stop when I saw the guts.... going to HF for a couple new tools, buy some beer and ... going to have a good day
His troubleshooting is horrible!
I watched your 4.7rebuild, great content and I was able to completely rebuild my Jeep motor. Do you have any tips to put the motor back into my 04 WJ? Specifically motor mounts.
Thanks, and keep the videos rolling. 😊
Great video!
I still call it a firewall. Bulkhead just doesn’t sound right to me, unless you’re talking about a house!
excellent work,, tanks for share😎
new subscriber, great content and excellent videos! keep up the good work
Great video.
Alright I'm starting this job on my jeep if I mess up the motor your responsible
Ha Ha Ha! Hit me up if you got any questions, email me BryansAuto916@gmail.com I'll try my best to help
Thank you I will hopefully I don't need to
How did it go?
@@10RFuentes
It WAS goin good till i broke a head bolt in the block. Never Never reuse head bolts!!!!!
I thought i odered bolts for both heads but it only for one head so i reused a set
On the passenger,side of 4.7 cracked valve cover and a hell of,aknock
Thank yo for ths jop✌🇱🇾
Awesome videos thanks!
With Parts and rebuilt heads this is what like a $2000 job? $1000 parts and $1000 Labor done right?
I see a lot of Trucks and jeeps for sale cheap with this problem and I am very tempted to buy them.
Maybe you can help me I got 2004 Jeep Grand Cherokee limited with 4.7 I just put rework heads and new timing chain used all good quality parts put back together it idols good but then you try to accelerate it blows the injector fuse
Great step by step! Used this often for my repair. Hey I'm second guessing something I did as @ 1st was running great now I'm getting mixed data that leads me to believe something is up with the PCM. Where does PCM get grounded to? Is it the back of bank 2 head sharing the stud with a ground strap? Thanks!
Hey Brian, awesome instruction on this. I have the same Jeep and actually same issue same #1 cylinder issue and jumping into it this weekend. I almost have it torn down far enough to pull head. If you viewing this do you really need to pull the radiator? I know if make it much easier I guess to get to the HB and pulling off water pump etc. but wondering if you have done it without pull the radiator and fan. Excellent detailed video as I haven't done this before but now ready to dig into it more since I viewed your video. Great instruction. Jeff All Speed Customs
You can Leave the Radiator in, but you gotta remove the fan!
@@Bryan916 And just having done this I can say it is easier pulling the radiator/fan together then trying to separate the fan from the radiator while still in the vehicle. At least on the hydro fan.
I’m getting ready to UNFORTUNATELY perform this same job myself. Not looking forward to it. I do like the bag & tag idea. I’m gonna haft to remember to do that. Also, is that the Harbor Freight earthquake cordless ratchet? If so how do you like it?
Amazon sells one for 59$ compared to earthquake 130$ I've owned both like the Amazon one better tbh
Thanks, I'll be done in a month or so, lol😎
You need a head camera for those tight places.
Please, can you tell me how the cylinders of the Grand Cherokee WJ 4.7 are numbered? Thank you . Jordan
That engine looks like a nightmare. Lol and that's coming from a guy with a 90's 2v 4.6 😂
What puller do you use for the balancer??
Great tear down.. Appreciate it..My story.. Old Radiator cracked, leaked all fluid, Cherokee 2000 4.7 over heated extreme, missfire & a P0307. Turns out no compression on #7. Spark has oil on it. Will mess a little more , but definitively don't want to go as far as you did without a shop/tools/ etc.. Without digging in, What's your opinion on oil on the spark? If not fuel intake leak, would it be necessary to strip it down that far? On the model in vid and mine, wouldn't I just be able to pull one side cover off and inspect? Not sure I even want to break the gasket seal.. Time for new car? ;-(
Great video, subbed. Who makes the battery powered ratchet wrench, the one used at 9:40 removing the alt?
That's a Harbor Freight believe it or not. It's a great little tool i never had any issues with it!
@@Bryan916 Cool, thanks! It looks like it's quite handy, no air hose in the way. Retired now however still do it quite a bit in the garage, doing my 04 GC 4.7 heads in spring as preventative maintenance. Made the decision right after my friends Durango dropped a seat at 150,000 and trashed the short block, mine has 140,000... Runs great but I'm not falling for the dropped seat trick, lol.
Smart Man!
The other head, how can I reach the two bolts connecting the exhaust manifold? There's no space, I can't see how you disconnected it. Understand the head is removed with the exhausted block, but that's bolted to the pipe right at the back.
Remove the two exhaust down pipe bolts and that's it, the exhaust manifold comes out with the cylinder head!
@@Bryan916 Thanks that's great! The two down-pipe bolts on the starboard side of the engine are covered by a load of pipes and stuff, do I have to strip all this off or is there an easy way to get to them?
Hell yeah brother are you around the Sacramento area ?
Hi there. Your videos are extremely helpful and I appreciate them. I am reinstalling the timing chains on my 2005 Grand Cherokee 4.7 do to a dowel pin on the passenger side cam shearing off. I have the timing cover and harmonic balancer already off. I rotated the engine so the idler pulley has the dot on 12 o clock and the crank has the dot at 6 o clock. Does that mean piston 1 is at TDC thanks.
My 4.7 HO engine overheated and some valve rings dropped into one cylinder, but I'm worried that maybe the engine is damaged, though it turns over easily. The alu head also has a 0.015 inch warp. I've only worked on Chevy SBC engines before so this is a big step in complexity. Any advice how I should check the block, maybe for cracks in the cooling system?
Great video Brian. You do quality work. But what happened to the rocker arm? Where did it go? You said somebody was in there before but why would they take out the rocker arm without at least putting it back? What struck the piston? Another mystery.
No mystery here the valve seat fell out keeping the valve from closing all the way and sticking out into the cylinder causing the piston to strike it. I know someone was in there before because it was missing a rocker arm that clearly someone removed! I'm sure you can guess why they remove it!
Good vid Bryan
Since you work on these 4.7's all the time, can you put the HO (265hp) intake/throttle body on the regular 235-hp motor?
I'm not sure but honestly I don't see why not, the only difference is the cam lift
@@Bryan916 I'm looking at an '02 Durango with good paint and body, clean interior and a very tired sounding 4.7. I have sourced a good reman engine, but they recommend replacing the intake in case there were any bits of valve guide that got impregnated into the walls of the old intake. I wanted to make sure that there weren't any bolt issues or sensor issues. Your different videos have really helped me learn a lot in a very short amount of time. You remind me a lot of Mr. Flockhart, one of my instructors at UTI. He took the time to not only show what to do, but also took the time to explain some of the hows, whys, and whats behind the steps and manufacturing process.
Oh, that reminds of another question. When I was looking at some of the engines available, some were described as 16 teeth and others as 32 teeth. I ended up finding one that was compatible with the VIN code "N", and that's what I will be going with. Thanks for the help!
Thank you for this video. Im doing the same thing with my 04 jeep 4.7 right now. Just a quick question. That damaged to the piston, would that cause any effect on how the engine run after you put the new heads???
What's a ballpark cost of doing this? Would it be cheaper to replace the engine or reasonable to do this? I have P0308. Pulled the valve cover and the last rocker was floating around in there. Replaced all lifters but it all back together and it came off again.. I'm thinking valve seat dropped
Check out pt 2 I kinda went over this topic of should you buy a used engine or repair your current engine. After watching pt 2 I hope it helps you make a decision!
@@Bryan916 thank you.
Prime example of why you are told, “20 hours of labor” then your bill racks up to “40 hours”. Dude works slow!
This might be the stupidest comment thus far! You obviously don't understand how flat rate works. It doesn't matter if it took me 40 hours or 100 hours the customer still gets billed the 20 hours Bro, so figure out what you're talking about first before you try to talk shit!
It's dumb ass ppl likethat that give good mechanics a bad name. People don't seem to understand that sometimes things that happen to old parts when repairing vehicles and if some brittle part breaks it has to be replaced
@@Bryan916 yup thats why when i was a mechanic i was the one doing all the engine jobs. i worked slow but we never had very many issues when i was done .. usually started right up . lol i used to be able to get the timing within a degree or so before i started them. but thats also why im no longer a mechanic. i never made any money doing it i was too slow. Flat rate can be brutal. but i changed 1978 Ford radius arm bushings in an hour and got paid for 4. that was a good day.
You're an f'ing jackass. He was working at an above average clip. I'm sure you'd have the heads off in less than 2 hours. Utter moron!
Is that a reg drill driver ur usein to take off the bolts
It's not a drill JT it's an Impact Driver.
@@Bryan916 ok thanks i orderd a Makita set just want to see if i can use that for little nuts and bolts on the car ....happy holidays
Good choice, Yeah a Makita Impact driver shouldn't have any problems removing small fasteners at all.
Thank for View Brother much appreciated!
Am I crazy buying a 2004 4.7L with 96K miles with same problem (no compression cyl. 1)? In really nice shape (body and interior), they are asking $3,000.
I was attempting to do a compression test on my 2009 Dodge Ram 1500 4.7l, but unfortunately my spark plug socket got stuck in the spark plug bore. I’ve tried to research what to do to get it out but everything I’ve found I either don’t have the tools or I just cannot do what they suggested. How would you handle that sir? Is it still ok to just begin to pull the heads out without compression testing?
If you know you gotta pull the heads any way, might was well start pulling them off. If you are not sure if you need to pull the heads and still trying to find out what's going on then I would work on getting the socket out!
@@Bryan916 my girls truck overheated, broke down, and now it will not start. I already replaced the radiator due to a huge hole in it and it still won’t start. At this point I’m honestly just assuming the truck blew a head gasket based on what I looked up and also what multiple mechanics and friends told me. It does crank and the starter is working fine, no clicking noise or anything like that. It just sucks cuz I wanted to be forsure before I started. I did try to run the diagnostic but that socket got stuck and i really have no clue how to get it out. Too much other components in the way as well. I didn’t want to just jump into but damn lol. Thanks for replying!
Do colored links on cam shaft have to line up before removing? Or can i just bring to TDC and then when i replace put them on correctly in each window and on colored sprocket tooth
thank you. Wish I could tip more, get lunch on me next week at least :)
Do I need to pull the motor out to change the head gasket??????
Jack up the tail off the transmission leave the motor mounts alone.
Really great job there man, how much it cost to fix it? my car got the exact same problem and repair shop charge me 2,000 bucks for clean the valve #7 Now im gonna do it myself because you man!
Chang Michael how'd it go??
Henry Fuentes it still pretty cold outside, I might get it done by May lol
What tools would you need to do this
Bro it skipped out of time for me for when I tried to removed it with a impact. Am I done for or what ?
Or can i just put it to tdc after I take the chains off ? Manually in each came and the harmonic ?
@@daytonthomas6778 I'm not sure what you mean explain it in detail @ Bryansauto916@gmail.com
You think manufacturers can figure out how to put more crap on top of these engines!
Just did this to my 07 commander. Followd the steps and i believe i did everything wright. I tried ti start it and it tries but hesitates and dosent want to start. It started a couple of times for a brief couple of seconds and dies. It sat for 4-5 months right above e on the gas tank before i finished it. Do you have any thoughts on what could be wrong with it?
Sounds like compression loss probably the timing is off.
valve overlap at the end of the exhaust stroke would make air come out the TB. Is there a timing mark on the damper for cyl 1?
Overlap is when both intake and Exhaust Valves are open momentarily. This does not happen on the compression stroke but on the exhaust stroke. Performing a Cylinder leak test, air would be escaping out the rear tailpipe as well and the T-body this would tell me it's not on the compression stroke but on the exhaust stroke, going back to the point I made in the video!
At what point did you take off the exhaust manifold or disconnect it? Having a lot of trouble doing it myself...
FretStomperJamo leave the exhaust manifold attached to the cylinder head. Disconnect the downpipes connected to the manifold. The cylinder heads comes off with exhaust manifold attached, only way to do it!
Are you from Sacramento?
what is that hose call when you took out the oil top. i tried to take out the hose and it broke so took the whole oil top off like you did. but i have to get a new hose now and don't know whats its called.
It's the PCV Valve Hose. The PCV Valve on this engine is located on the oil filler.
fire wall or bulk head,,
i have always heard it called a fire wall by everyone i have ever worked with,,, the only time it gets called a bulkhead is by the collision estimating program, insurance apraisers ,(who have never actually worked on cars) , or their supervisors,,,and brand new grads from auto tech schools,,, i'm gonna guess that it's always been a bulk head, an engineer would probably call it that,, but as far as i see it, it seperates us from the "firing " motor, so we can be kept safe from catching on fire , hense , the fire wall , that was how it was explained to me by my first boss, Louie Gabriellie ,at maaco,,and he was orriginally a mechanic,, but lots of things have different names, like a jamacian would call the hood a bonnet,, and a trunk lid is called a deck lid,, etc, and so on
I have a question about to do the same engine head gasket on my wife's Jeep the head gasket blew but it is not mixing water and oil it's just overheating and we've already had it checked out and it is a blown head gasket now my question is somebody told me that I could just go ahead and swap head gaskets and I'll be fine do I have to get the head resurfaced someone said no because it's a iron block I'm just curious if that's true or not thanks
Doesn't matter if it's a Iron block! To much heat will distort any type of metal. You always have the Heads checked for cracks and have it machine true when doing a top End Job this is key to the Repair process! But honestly you can't heat up these 4.7 or the valve seats will fall out my advice to you is find a good Machinist have new valve seats installed along with the other machine work!
What was the total cost of parts for this job?
Hi Bryan916 we are have a misfire issue with our 2011 jeep grand Cherokee. I know you closed your shop but do know any one locally in Sacramento that could help . Two shops are telling us just to replace the engine at 9k for the low compression on cylinder 3.
It shouldnt cost 9k lol your getting ripped off
An entire engine rebuild and machine is like 4k 😂
You can buy a junk 2011 and just drive both cars to a shoo and say hey ... Put this engine in that one and they will for like 3 grand.. And then you tow truck the parts car to the acrap yard.
How could it be tdc on a compression stroke if the intake valve is open?
Right, so there's your problem, It must be a valve not closing right? maybe watch the whole video or skip to the end to see what the problem was before commenting!
@@Bryan916 smart ass I figured that when I typed the comment. Mad at me because you spitting incorrect information
