Threw a lifter… what now?

[woketradr]

This sounds JUST like mine, I am just finishing up my delete.
Truck norris cam and performance lifters.

I had a collapsed open lifter and it spun got chewed up just from driving home slowly, cam was okay but the one lobe was not smooth anymore.

The lifter mushroomed and was stuck in the bore, I had to pry it out and sand the bore.

I was luckily able to trailer it home with our circumstances. So it ran maybe 3 mins max with the collapsed lifter.

Yesterday I successfully un collapsed it and threw a range device on it to disable v4. I drove it 4.5 hours this morning at 70+ mph and it did just fine

I will probably replace the lifters at some point in the future. It just happened that the lifter collapsed mid move so I’ll do that later

I honestly don't know. it's pretty easy to pop off a valve cover and check for a broken spring.

what year and how many miles? there's tons of info on delete kits here. I haven't personally done it myself yet. mine is turned off and hanging in there.

are you able to diy a delete. if not, it gets pretty expensive to pay a shop. most of them want to sell you a reman engine

I just had the same experience with my 2017 Yukon 6.2. I drove it for 5000 miles with a small tick and got worse. Took it in to a local shop and had it diagnosed. It was a failed lifter which took out the camshaft too. The roller lift was about to fall apart and ruin the engine block. So I went with the Brian Tooley DOD delete kit. Runs like it should and costly after all it was said and done. Had to reprogram the computer but will worth buy a whole new engine.
