How to change head gasket, lifters, pushrods, rocker arms. Engine knock 2010 GMC Yukan XL 5.3L

Welcome back guys. In this video I got a 2010 GMC Yukan XL with 5.3L and active fuel management system. Those system’s solenoids are known to fail and cause lifters to collapse and cause a massive engine noise, that you will hear louder towards the top of the engine. I will show you in this video step by step, how to disassemble the heads, change lifters, pushrods and rocker arms. Also how to replace the head gasket and torque everything back down.

This video is great. You really walked me through my 2012 Yukon XL Denali. Great job.

[@ImNotHereToArgueFacts]

1st time I ever heard of anyone not deleting the AFM.

[@p.j.desrosiers4127]

Thanks to your video I was able to do this job on my own. It saved me $3k-$4k in labor! Great detailed, step by step instructions. Thank you!!!

Where did you get parts from?

[@kittshausman6191]

Thank you buddy help me a lot of my 2009 Cadillac hybrid. Replace a lifter cylinder 7 misfire it’s broken. 😊

Just wanna take the time to say thank and I got too much love for you and your videos‼️💪😎💯💯👏😇

[@benjaminchute1602]

What an awesome video. Great explanation. Good angles. Good lighting. Very detailed. Thanks for the help! Question: The part when your camera died, you started from TDC on Intake side first? Then rotated 360* to torque exhaust side correct?

[@a2zautomasters862]

Thank you for watching and I really do appreciate your comment. So the way you will do this is to set engine to TDC and Torque 1,2,7,8 Exhaust rockers and 1,3,4,5 Intake Rockers all to 22lb then Rotate crankshaft clockwise 360 then torque 3,4,5,6 Exhaust rockers and 2,6,7,8 intake rockers to 22lb.

Where did you get the parts to do it?

[@danielcamarillo4988]

Hey man great video thinking about doing it my self, one question though. So my 08 tahoe lost oil pressure due to oil pressure sensor failing so I replaced the oil pressure sensor and crank shaft sensor, does the loss of oil pressure cause any more damage other than lifters? Will I have to take a look at the oil pump, thank you in advance

[@mdelano]

If the oil pressure sensor failed that doesn't mean you lost actual oil pressure. So it would not hurt the engine. These sensors fail all the time, it's common. I would not worry about it.

[@razmigbarsoumian9161]

My cylinder 1 lifter is bad Can i change only 1 side of the lifters ??

[@darkmatter7399]

It’s best you do them all. But if you must pick and choose I would at minimum do the whole row of AFM lifters. That’s the bare minimum though. It’s better to replace the whole row and even better to do all of them. It would be EVEN better if you did the cam too along with rods and springs.

[@joshhernandez2144]

Is the little tick normal? Mines did that after fixing

[@a2zautomasters862]

If everything is right, shouldn’t be any tick.

[@joelok700]

Yes. You can hear it at the end of this video still. It's normal

How did you get the manifild off from the top ? Can hardly fit your hands

[@halofan8211]

Extensions and swivel bits

[@jhayjay-2x]

At 34:16 would be the best time to inspecr or change both engine mounts🤙🤙

[@a2zautomasters862]

That’s 100% true. I actually did replace the driver side Engine mount on that truck, off camera

[@edwingomez7444]

What does something like this cost for labor only ?

[@LH81633]

Got quoted, 5-6,000 lifters and cam!! As you don’t want to change only one!! You’ve basically already paid them to open it up! That’s where majority of labor was!!

[@MegaSendit]

Where are you guys located ?

[@a2zautomasters862]

Sorry for the late response. We’re in garden city NY. Long Island

[@redryder8834]

What do you think?? Make yourself some cool t-shirts to wear when you’re filming the vids

[@dantejuantero6989]

Turns out the seal for the gasket was written wrong so the front was the back and the back was the front

[@tavyakangler3419]

No need to replace the whole head ? I have a 2009 denali the motor shaking and poor idle #4 cylinder has no compression is what the diagnostic says i want to know what do i need to replace, just the lifters , pushing rods and gasket or the whole head

[@smiley3303]

You will have to take the head off and see if piston and cylinder walls are okay. You could do a leak down test to see too but that will only tell you there is an issue. To figure out if piston or cylinder wall/block you will need to get in there or use camera. I am in the same boat on 08 taking it apart soon to see what failed.

[@tavyakangler3419]

Thanks i just remove the heads and yes #4 is bad also all the lifters are the sort ones no spring kinda a wired

[@smiley3303]

@@tavyakangler3419 shoot! I am taking the heads off on mine on Friday and I think 5 is going to be the one with a bad piston. The 6.2L is great when it works but was sad when it died. Spring was broken on 5 and push rod was bent.

[@LH81633]

Lifters and cam!! Leak test heads!! Get machined if needed!! Never only replace just one lifter or only lifter or only cam!! They all work together!!

[@LH81633]

@@tavyakangler3419someone most likely did a delete on it, or it didn’t t come with fuel management system

[@user-lr9fq4eh8p]

How did you drain the coolant gm is so stupid with these things

[@louiebober2428]

So $2800 to fix this problem on my 08 Yukon is well worth the money.

[@hdddgg]

There should be 16 lifters on each head?

[@LH81633]

🥶🥶🥶🥶

[@LH81633]

2 per cylinder,

[@alanpoisel8030]

I think you're better off to do an AFM delete immediately before a lifter fails & damages the cam..
