I have been a mechanic for over 50 years. I listen to advice and give some also. At the end of the day if it works for you it's right. I never tell another mechanic he's wrong, I just say there's another way of doing it. it's up to him if he uses it.
This is absolutely correct!!! I also feel that the best way to learn is to listen to how other people do it, then make your own decisions on what is best for you assuming it is still done safe and correct. I dont have the same level of experience but I can tell you a lot of the " ol timers" in the dealerships always hated when I found ways around the book to get things done faster and easier at times. There is always more than one way to skin a cat. Thanks for subscribing!

Great job bro..
Please turn off music libit less to hear you
Better.
Thank you,
Yeah, I've learned a lot since this was edited. I hope it was helpful and not too distracting. Thanks for watching.
Ty, for this help!!!
Glad I was able to give you help. Thank you for watching and commenting.
I’ve done a 3.7 and am doing the heads on a 07 Grand Cherokee with the 4.7 now. The time it takes to remove the timing cover and chains is a fraction of the time it will take to try and and keep the chains tension correct or have to reset the tensioners. If it’s time to do headgaskets it’s probably time for chains also.
I agree; the only concern then is cost. It's easy to say you would with your own car. But, not everyone is willing to spend on parts that may or not be worn and need replacement. Thanks for watching.
@@willpoweredgarage969 hey when you did ur timing cover gaskets the little circle one how does that come out?
@@waynestalnaker47 yes I second that question, it's a 3in circular plate with gasket built on
@@lucxidmusxic2098 I actually just pounded it out easily thanks
@@waynestalnaker47 looks like it's a gasket for the crankshaft, I was afraid to pound on it but I did have a new one sitting here
I wish the 09 3.7ltr had the same clearance as this. Wiper cowl won't allow intake manifold to clear...so to my understanding you have to drop the engine or cut the cowl. For clearance Great job btw
Yeah, that does not sound fun on an already pretty big job. Thanks for watching and commenting!
Please, can you tell me how the cylinders of the Grand Cherokee WJ 4.7 are numbered? Thank you . Giordano
No problem, Sorry for the late reply. Driver side goes 1,3 ,5,7 PAss side goes 2,4,6,8
👍👍👍👍👍
Thank you!
Hey I have a 2006 grand Cherokee with a 4.7 and my lifter sleeve broke a little bit and so I'm gonna replace the passenger side head and was wondering how difficult it is and any tips because it will be my first time removing a head on it
Its relatively straightforward. Just take your time, make sure all the gasket surfaces are clean and dry before reassembly. The timing system can be a bit tricky but if you follow the steps in my video it should clarify it for you.
@@willpoweredgarage969 alright man I really appreciate it. I was hoping it wouldn't be to difficult
Hi is the same for the 3.7 engine 07
Yes, The timing chain setup is the same. Only difference is 2 less cylinders.
Onde fica o 1 cilindro?
Driver side bank of engine, front cylinder.
How much did you charge for this job?
Not sure off the top of my head but it was probably in the $1600-2,000 range for parts and labor.
Isn’t just better to put a reman engine? All the labor just to this repair and still have an old engine.
Well, a reman engine is at least double the cost of this repair plus the labor to replace it. Besides, why replace what's not broken. The engine runs great otherwise, just needed new gaskets.
Oh I see. What was the mileage? Have you done valve seals replacement on these engines?@@willpoweredgarage969
Not a fan of these overhead timing chain engines rather change a timing belt every 60k then change one of these chains.
Yes, They both have there advantage and disadvantages. IMO, If you create something that will need replacement one day, make it easier to access! Thanks for watching.
You explain all the nonsense so clear but when it comes to taking something apart you you Speed up the video and don’t say anything? 3 minutes explaining the pin but nothing on how to put pin in
Sorry about that. I'm a much better tech than video editor. What questions do you have about the pin. Maybe I can answer them for you now.
This comment was at the heat of the moment lol I could not figure out how to properly squeeze the tensioner to got the holes to line up so I tried to pry what looked like the same spot you were and snapped the guid where the chain rubs
I turned this off after a few minutes of the music. I really hate watching a video with unnecessary music. This music DETRACTS from what may be a great video; it adds NOTHING!
Thanks for watching!
Shut up the silly music so we can hear what you are saying
Thanks for the tip.
