Collapsed lifter help please

[Michael Johnson]

Hello I have an 09 suburban 1500 4x4 with the 5.3l and AFM. 150000 miles. I got it with 100,000 miles and dont know any history before i got it.   I had a loud knocking so i took my passenger side valve cover off and found my i take rocker on cylinder 4 was loose.... collapsed lifter.  

Do I replace the one lifter?

300 bucks for head gasket kit and lifter

All the lifters?

550 for gasket, bolt, lifter kit from amazon

Do I get a new VLOM?

250ish on amazon

 

Im just not sure how much i should or need to replace.

Thanks, 

Michael j

Replace one lifter and you're likely to lose another one at any time.

 

Go with new lifters all around (16 total, Non-AFM lifters), new head bolts, cam bolts, head gaskets, crank pulley bolt, cam gear and bolts (3 bolt conversion kit), GM 5.3L LM7 cam, and oil pan gasket.  Should probably change oil pump also (the shop I used suggested changing the pump since the engine would be out anyway...get a Melling).  Also, get a tuner or Black Bear tune to tune the AFM out.  I went ahead and had them change the rear main seal also while everything was out of the truck (with my luck, it would have started leaking as soon as I got it back).

 

You can configure the kit on their website (https://www.texas-speed.com/p-717-dod-afm-delete-kit-for-536062-engines.aspx), but I called them and they walked me through everything that I needed, but didn't try to push me to buy anything extra.  Placed the order over the phone and the kit was delivered in about 3 days.  Great customer service!!!

 

I just had this done earlier this year, and ordered everything except for the tuner from Texas Speed and Performance.  Parts came to a little over $600 and tuner was about $250, if I remember correctly.  Being in the middle of a shutdown at work, it would have been several weeks before I could get to do anything to it, so I had a local shop install everything and labor was about $2200 and I had the truck back in about 3 days.

I'm in the same boat as you. I had a lifter go out. I bought a new cam and DOD/VVT delete kit from Brian Tooley Racing (their support is AMAZING to say the least). If it was me I would replace all of them and do away with that garbage DOD system.

Just got cam out. Found my cam bearings are screwed. The engine has to come out. The DOD cam is garbage.

It might be Possible, but not likely that a lifter will "collapse." Much more likely that the cam lobe is toast.

So what did you end up doing?

Looks great, how does she run now?  How's the mileage with that camshaft?

Runs great its night and day difference. If I baby it i get about 17 combined drive it normal is about 15.5.
