[Rauleezy22]

Thanks man. Used this today.

[ruckus5150]

hes calling .004 "40 thousandths" is that right? i thought .004 is " 4 thousandths"?

so what is the gap? .004 or .040?

Anyone know what size socket would I need for removing a PCV on a 2006 Grand Cherokee 4.7L? The PCV on my Jeep GC model is way back drivers side, screw in type and hard to get to with lots of stuff on/around it. It requires a socket for unscrewing/removal according to online posts. What size socket do I need for this job and any other tips? How deep should the socket be? This is the new location for the PCV, not to be confused with 05 and early 06 models that had the PCV on the oil filler pipe.

What do you do when your coil packs are stuck?

[Rebel9700]

that 10mm he uses is more of a rachet.

[jbrunsonjr]

@Rebel9700 - You are correct - sorry about that!

[klhudson1957]

@Rebel9700 A nutdriver does a better job on those clamps.

I miss the old V8s where it was simple! I just picked up my grand cherokee a few weeks ago went to go do a tune up lol looked for the plugs and I was lost! Thnx for the video helped me out so much! Is there a cap and rotor on this motor and if so where? I like to do my own wrenching but these newer engines unless you have schooling there a pain to figure out! Thnx again for your help!

[rockshox101avidjuicy]

@MaximD9 no cap and rotor in case you hadnt gotten an answer (i realise this was a year ago), it's got the coil packs instead

[ivrplayer1]

Great Vid, Really Helped alot on my 05 dodge dak. What size is that spark plug socket?

[dnl5649]

unless your a woman, i understand why you would need to see a video on how to change sparkplugs. now if you were making a video on how to change the plugs on a front wheel drive car where the plugs are in a very hard to reach place

[jbrunsonjr]

@dnl5649 - Everyone has to start somewhere when learning to wrench, and this is probably one of the easiest things to start off with when learning. I've built a couple of old CJ7's from the ground up, but just dont have any project vehicles right now to film, so daily maintenance vids it is for now. Hopefully next year I will have enough cocheese for a more fun project to record...

@dnl5649

And if you were even half a man, you wouldn't feel the need to troll.

[ms610172]

Good Job i need t replace spark plugs

[jbrunsonjr]

@ms610172 - Thanks! I say just jump in there and get it done. It's not that hard of a job and your Jeep will thank you for it!

[wishiniwasfishin27]

You will find as i did on the last plug that is much easier to remove the piece between the coil pack wiring and the plug if you disconnect the wiring connection first instead of pulling out of head connected, great vid keep postin!!

[jbrunsonjr]

@wishiniwasfishin27 - Yeah, I realized that after I had done that. I appreciate the tips (constructive criticism only makes my life easier in the long run!), so if you have any more, please share them! Thanks for the kudos as well! I actually have a budget boost lift video that I will be posting up later tonight, so keep an eye out!

[snf09]

nice engine, i like how the alternator is right up front, easy removal. nice.

[joshnc101]

I noticed that the intake box had a clamp where it connects to the throttle body, my 04 4.7 Dakota didn't have that and neither did my brother's which is the same exact truck and motor I have. I just discovered your video and I had already changed the plugs on my motor a month ago. I went with NGK V-Power and compared to the worn out factory Champion plugs, the NGK's made the motor run absolutely smooth! You cant feel it running lol. How have those Autolite plugs been treatin ya?

[mperu99]

You didnt blow out the plug hole before removing the plug!.. can you say debris! now in the engine

[jbrunsonjr]

@mperu99 - Yeah, I know - tell me about it. Unfortunately I don't have an air compressor. I will try and add that step on my video soon...

[SteveinJamestown]

30,000 miles on my 2006 5.7 liter jeep and I use an ax handle to prop up the hood. I like the vice grip version.

[PhOeNiXpIoLe]

its safe to say this video will be closely simular to the earlier 4.7 models 1999-2004, its prolly easily on the earlier models thou

[spikedpunk]

How did I miss this one? Everybody loves spark plugs except those of us who don't! Sweet! Coil on Plug boots, it was good you mentioned to inspect them carefully, indeed, on some engines, failures of both the boots and the coils is common. The Ford 4.6 is certainly one of them. The high temperatures and lean running conditions mandated by emissions standards all add up. Good movie here!

[jbrunsonjr]

Thanks Howie! I don't know near as much as you do, but I just hope I am helping out with what little knowledge I have to all the newbs out there. Once they realize that it isn't that bad to work on your car, the better!

[spikedpunk]

I try and help all my friends and people in the most polite and dignified way possible. We all can learn and grow from the help given to one another. I think it is brave and good for you to do these movies, encouraging others.

[cougar1233]

You did that tune up like a pro.

[jbrunsonjr]

Thanks for the props!

[TheDelahaye]

My Jeep hood struts are gone too. I'm gonna get me a redneck tool like yours! Great video, I've had my v8 for a couple of months, its my second Jeep and I'd love to learn more stuff like this

[jbrunsonjr]

Thanks! I love this Jeep, but really miss being able to drop the top on my CJ7....

[gd9704]

Thanks. My wife's jeep is due for this, and seeing your video makes me a bit more confident in getting it done. Thanks for your great videos!!!

[jbrunsonjr]

Thanks man - it's all about investing in the tools right off the bat (money you would have spent paying someone else to do it, then you have them for life). The hard part is just motivating yourself to do it. If you can, get a Full Service Manual online (can usually get them for free off of forums) or a Chilton/Haynes manual and it will walk you through step by step with all the correct torque settings....

[Jabbajawz4life]

Dude become a mechanic lol!(POOT)

[umajunkcollector]

good advice on the proper tools. Those spark plug sockets have that insert which also prevents breaking the porcelin too.

[jbrunsonjr]

Exactly - tools are such a great investment. Those sockets aren't very expensive and well worth their weight in gold!

[csxgk94]

i got a k&n air flow in my truck

[jbrunsonjr]

This is actually the first car I've had where I haven't changed mine out. Guess I should get to it! :D
