5.3 AFM/DOD lifter release trick,will it work? Chevy Avalanche bandaid job@Vassmotorsports

[dustindunphy]

This is great info. I have an 03 Av. It's been a great rig. Now my wife's 2010 yukon has a collapsed lifter on 7. I saw your other comments about a full delete. I guess we'll see where I end up.

Thanks for your time making this!

there is a much easier way to unstick a stuck lifter we old guys been doing from the 60s up. just take off the valve cover and with the engine running take a hammer and tap on the rocker tappet over the push rod. you keep taping till you hit it while the push rod is mashed down as far as it goes. the extra pressure mashes the lifter down further than normal and the oil extra oil pressure the hydraulic lifter pushes the thing up and releases it. that way you only remove the valve cover. this also will make lifters not pumping oil up through the push rod start oiling again.

Thank God for wisdom and thank you for sharing

Good vid kinda love my avalanche if my lifters collapse again ill give this a try.

[KayLee-wloz]

good luck with that man you seem to be able to do it

[nategrunewald]

Nice work. But if you're not going into the ecm and disabling active fuel management, chances are once DOD activates again the lifters will re-collapse. I used HP tuner to disable AFM.

Great observation! Thanks for sharing!

I wish you had filmed the air pop... and how you put the lifter back together

[chrisloveall]

I was watch that video where crazed had it on an he showed once the lifters release before you put the rocker you have tap on the end of the pushrod an snap the lifters back onto lock position before putting the rocker on .

I was thinking about using air, before punching it with metal. But also using some hydraulic fluid and some type of plunger. And try to hydraulically release the lifter. If all else putting a grease fitting on the hole and pumping grease into the lifter. But who knows it's just a thought. I have a 2007 Avalanche. I thinking just pull the heads and do it right. If i did the delete im not sure it would pass smog. Or maybe filling the hole up with oil before blasting air might be an ideal.

I’m looking at a 2013 Silverado with misfire on cylinder 1. I was thinking if I get it, of taking off the valve covers and replacing all the lifters at once and then running one of those AFM disable modules that plugs into your OBD2 plug. In theory they should never collapse after that because the system just runs in “V8” mode after that. Would be cheaper than doing the full delete kit. What are your thoughts on that?

I make a tool exclusively designed for this. That tool has too small of a point. Having that small point risk damage to the lifter if it lands at the edge of the oil hole. The air only activates the locks. The hitting of the tool probably loosened it pryor. The air alone wont work because the locks are not the part that is stuck. If you get another you will likely find that out.

Did you not test drive it before you bought it?

[dvnp]

Curious . With it still knocking did u fix it ? Looking at the motor the passenger side head had a noticeable gap between the head and block

[nelvag]

I have a 2005 avalanche . It's ticking off and on. Does oil pressure have anything to do with the ticking?

[lovelove]

My gmc sonoma 4.3 keeps coming loose after adjustment is perfect earlier, why are the rocker bolts backing themselves out. It's only a few cylinders doing it, I recall. Any suggestions to keep the rockers tight and torqued ?

Just bought a 5.3 for my 2009 Avalanche and it was 2450.00 with exchange. We had a lifter spun in ours. And it has 229900 miles on it.
