You're so easy to follow...thank you😁

[@s33therfan]

awesome feedback , thank you

[@mr.wisdom5337]

I just want to say thank you for your video. I began working on mine today at 8 AM and I finished by 5 PM. I took my time and followed your instructions. You're truly a godsend.

[@s33therfan]

Truly appreciate the terrific feedback. Thank you for watching.

[@christophermeyer6414]

If I'm not mistaking, you put the new spark plug tube oil seals in the valve covers backwards. Great video!👍 Answers a lot of questions!

[@renan8486]

I agree. It seems backwards. Other than that the video is great

[@edwars5925]

He definitely did put them back in backwards. I wonder if it affected the operation if any?

[@DionGriffis]

He did put then in bkward

[@pedrodelasancha516]

Great video. Easy to follow. One HUGE tip. You didn't have to remove the hoses for the Power steering reservoir. All you had to do is remove the 2 nuts holding the reservoir to the bracket and move it aside. Then just bent the bracket outwards to get access to the One Valve cover bolt hidden under the cover protector. That's all. Then once the valve cover is reinstalled just straighten the bracket back to it's original position. Done. Again, great viceo. Very well put together.

[@bravesrockmysocks]

THANK YOU. This was the one step I was stressed over.

[@MBROWNTN1]

I'm about to be doing this same procedure this coming weekend. And I am thankful that I finally came across your video. You go into so much more detail then the Haynes Manual does for the valve covers.

[@s33therfan]

Thank you for the terrific feedback, it is greatly appreciated.

[@Sapper86]

Thank you for the video. I'm about to do my timing chain on my 2010 Acadia. Your video was the only one I've found that shows step by step on taking everything apart. Every other video I've seen just has everything taken off already. Again thank you and wish me luck.

[@s33therfan]

Awesome feedback , it is greatly appreciated.

[@troutsnout]

Thanks for sharing your experience. I just got done doing the same job on my wife’s ‘08 Acadia, and I couldn’t have done it without your guidance. I found that I didn’t have to remove the motor mount. Also I removed the smaller front hose from the power steering reservoir and capped it off while I suspended the reservoir from the windshield wiper with a small bungee cord. Then I just removed one bolt from that bracket the PS reservoir was bolted two and rotated it forward. After bleeding the PS system when I finished, and discovering I forgot one wire connection and the rubber nubby thing that goes vacuum port on the back of the intake manifold fell off, she’s back on the road!

[@s33therfan]

I appreciate you taking the time to share this and the great feedback.

[@Seeker887]

Label, tape, pictures, and zip lock bags help take a lot of the guess work out of reassembly. Really appreciate your Acadia videos. I’ve yet to need them.🤞but watch and 👍 thanks for sharing

It be dope if u had a video separate just of the cleaning of the valvecovers cleaning fans top of engine alone

[@s33therfan]

Great suggestion! Thank you very much for the feedback.

[@ll_avail_ll9050]

Need help after completing these steps we tried to start it up no power not even a crank or click bought a new battery, it still has no power nat a sound we double checked the connectors alls in place , I’m thinking it could have been the fuse box after taking in off then placing bit back but it’s simple steps I appreciate your video very much nobody has this model vehicle sets if you can give any info as to find the source of power to star the acadia 👏

[@ABrown-pr1oq]

If you spray PB Blaster, on connections like that it'll loosen and lube them up and then they'll come right off, if you have time to let them soak a little while.... I even use PB Blaster on stubborn electrical plugs, to get them apart.. I just use PB Blaster on a BMW thermostat yesterday, where the hoses with the clip that holds them on don't like to come off of it, so I took it soak them and let them sit about a half hour came back and they popped right off. And I do that to prevent breaking anything... Try it, PB Blaster is the truth...

[@s33therfan]

Thank you very much for sharing and the great feedback.

[@victoriamorris7619]

Thanks for the info

[@sighnotes]

Thank you for this, I just got a 2008 Acadia and it has oil leaking into the spark plugs. But any idea why the transmission control would turn off after I did this job?

[@s33therfan]

I first reaction would be it was a coincidence, however I would check all the wires , grounds , fuses , connectors etc. Wish I could be more help. Thanks for the feedback.

[@sighnotes]

@@s33therfan yeah idk what happened

[@majorwootton9130]

The 4 upper intake bolts, what was the torque spec?

[@chrisk5142]

I thank you sir for making this 🙏! I am about to get into it and do the timing chains. The front cylinder has a very loud tick. How can I tell if it's a rocker, or a lifter? Thank you again!

[@ericalbino5038]

I hope after all the work you cleaned the PCV and the rear valve cover PCV passage. They all clog up and cause sludge and carbon in the engine, I have a 2010 Acadia I'm going to do timing chain's on Not going to enjoy that job!!! Great Video BTW !!!

Oh boy. I just bought an Acadia that’s leaking from the rear valve cover. I figured it’s just a valve cover lol jokes on me huh. Someone at gm needs to be smacked for this lol 😂

[@s33therfan]

Yes , huge job for a valve cover gasket. I agree totally. Thanks for watching.

[@shortdog11]

hi there sir what hose connect to the little silver pipe on the back of the intake manifold

[@autumbaby6225]

You made it look easy just don't think its something i could do thanks for the video would you know how much this would cost at a shop

[@s33therfan]

I am not sure , maybe someone else can chime in. Thank you for watching.

11:12 for the line, where can I find to plug on, cuz my have off but I don't know it's normal o not

[@semyonglukhoy494]

Hi, at 51:31, you show plugs on the passenger side of the rear cover. What is the plug closest to the front of the engine? I broke the part connected to the engine, where it plugs into.

[@peternudelman1597]

Great videos. Where are you located?

[@TrustOnTom]

Valvolines offers a product that is advertised to address the gunk in your crankcase called Top Treat. I haven’t seen any before and afters for myself

I will check it out , thank you for sharing this information.

[@helpinghands5940]

Thanks for the video. This job sucks, especially the freaking clips. And i chipped the cover near the chains in the front -or someone else did it. Hopefully it doesn't leak, it's chipped on the inside. Can JB Weld be used to fix the chipped part?

[@s33therfan]

I would think so , and depending on the size , maybe rtv alone. Thanks for the question.

[@straighthustlebullyz5315]

How did you get the car to turn on after doing all that my acadia won’t start I did everything plus the water pump and thermostat

[@s33therfan]

Sometimes I have had to give them a shot of starter fluid , with other vebicles. Not sure why but it happens and I have ran into the same issue swapping an engine. Once it fires up initially the car starts good from then on. Thanks for the feedback.

[@FixingCrappyCars]

Hey, doing diagnostics of my g/f's 3.6 in her 2008 Vue XR. She drove it, came home, then the next night it cranks but wont start. 200k miles and has had timing codes for awhile. Tested battery, good. Replaced the starter and tested the old, both good. Tested fuel pressure, good. Disassembled down and removed one valve cover. Chain is still connected at least, so not broken. Any ideas? Driving me crazy. Why would it be shut down and work and then all of a sudden not work now?

[@s33therfan]

I would check for spark and do a compression test . Usually timing codes popping up is not a good sign , but I would check the basics and go from there. Thanks for the feedback.

[@Curteezy09]

Have this video saved to be watched later when I have more free time. Quick question though, is this the same motor that is in the 2011?

[@s33therfan]

The engines are different , however the transmission can interchange with the tcm swap. Thanks for the feedback.

[@bravesrockmysocks]

Appreciate the content!!!

[@s33therfan]

Thank you so much.

[@blazingverde]

How much work would it be to replace the intake valves?

[@s33therfan]

It would be a pretty good job. The cylinder head would need removed and resurfaced before replacing it. Thanks for the question.

I regret the day i financed my 2010 Gmc Acadia SLT. Its been nothing but problems and leaks

I "was" planning on changing my valve cover gaskets

[@MustangFourSix]

Hey did you fix your acadias oil in throttle body issues if so what did you do.? Part numbers if possible

[@s33therfan]

I cleaned the holes on the vacuum line spouts going into the valve covers and that seemed to help. Plus cleaning the valve covers themselves. Purple cleaner , scrub , rinse and repeat. Hope this helps.

[@aaronjiran3837]

@@s33therfan I have seen a fix for the pcv valve going around in the camaro community with the 3.6. They are installing an oil catch can and then drilling the 2 holes on the bottom to 5/64th's and the single top hole to 7/64th's. Also helps the motor breathe better to help with timing issues and sludge build up down the line

[@s33therfan]

Great information , thanks for sharing.

[@danielclark8578]

How long would it take to do timing after you have it that far disassembled

[@s33therfan]

I would allow about 3 days . Pulling the timing cover , timing, and resealing everything. Thanks for watching

[@jerrodwhittington3009]

What did you use to clean valve covers?

[@s33therfan]

I only used purple cleaner and a scrub brush. You have to rinse it well afterwards. Thanks for watching.

[@robbya6113]

Thinking about doing this job to my 08 Saturn outlook XE, did you ever figure out what to clean the camshafts with to get all that junk off? Also awesome video man!

[@s33therfan]

amzn.to/38L5h8u Other than a engine flush , there is not much that can be done without a total rebuild. The problem is even if you get the cylinder heads spotless you still have all the passage ways and the lower end as well. I do believe several flushes and keeping the oil changed can help. Another area of concern is making sure the hoses and spouts coming off the valve cover are cleaned and allowing vacuum. Hope this helps , thank you for the feedback.

[@majorwootton9130]

I had a little misadventure with the heater inlet assembly snapping at the junction, the coupling was made of plastic and had gotten brittle and didn't take much to break it. I broke it while trying to get some room over the back right valve cover bolt. That halted progress for a week while I waited to get the new one in which has an aluminum coupling, so it should be good there. I'll have to replace the outlet assembly down the road, they're about $100 apiece and the way they're made, they have quick release clips except for the one hose that connects to the heater core. I only broke one so I replaced one. While this was going on, I had the alternator give out on my car so I got derailed to replace that, which is an 03 matrix xrs. I got both valve covers on now but i'm in the process of cleaning the surfaces of the upper and lower intake. I was using scotch brite pads but noticed a lot of debris coming off from the pad so I switched to a dremel with a soft brush attachment and then took some brake cleaner and shop towels to clean the surface. I had go stop when the dremel battery died, plus it was already dark outside so I get back at it today before I head to work

[@robgracia509]

I have an oil leak and they telling me its the valve cover were they leaking oil

[@s33therfan]

These were not leaking and as a matter fact all of these I have worked on have not been leaking. However once they are disturbed/removed they can and will leak. Other than that these engines actually seem to be sealed up fairly well , that is atleast one good thing. Thanks for the feedback.

[@robgracia509]

What do you think is leaking it's on the back side of motor

[@robgracia509]

It's not in the front of motor

[@s33therfan]

It most likely is the valve cover . Try if possible to reach back and feel with your hand and if theres oil then that is the culprit. Another area is where the vvt solenoid come through the valve cover ; check those for leaks. Those seals can be replaced without removing the valve cover. Hope this helps.
