Post DOD Delete engine noises

[Darren2014]

I’ll also look into finding an autocal for the tune possibly. If my friend with HP tuners falls through that will be the route I go. I do understand that the vehicle needs a tune just to clarify and I have had the intent to get it tuned from the start. But I can tell the problem is of a mechanical nature. My dad has a buddy that’s a tech at a local shop that will stop by and look at it tomorrow. Fingers crossed for a quick diagnosis but I have a feeling that it’s not gonna be an issue or two wires being switched backwards (tho that would be awesome lol). I really think I’ll find the issue in the phaser. And if it is torn up like I’ve seen others before then I’ll make an attempt to slap the old phaser on and see if I can get it on the second try before buttoning everything back up. Fingers crossed. If all else falls I’ll get a VVT delete kit and just live without. I’m sure I probably won’t notice it not being there.

with the vlom unplugged it defaults to 4 cyl mode...even though youve physically removed those parts, it also cuts fuel to those cylinders.

I got my "you learn something every day" out of the way early today.

I’d never read that before but after reading into it, it seems you’re right. I’ve got my tuner swinging by later. This might be all I needed.

You gotta check out Randeez's build thread when you have time.

Randeez 2012 Budget Yukon Denali Build (stick on hood scoops galore)

I hope he "signed" them like he supposedly signed mine. I'm saving that surprise as long as I can. The way I figure it, if I hold out long enough, buy enough, I can't have randeez 2.0, but in avalanche form its been so long i dont even remember if i did do any weird shit to those

And a transmission input shaft delete…

Welp it was the tone! It drives great now. Couldn’t be more happy. Thanks for the help guys.

Did everyone soak their new lifters in an oil bath/tub before the install?

I dropped my new LS7 lifters in oil jug with fresh oil for 48 hrs before reassembly

My OEM GM lifters soaked in fresh oil for about a month. I also used an old push rod and pressed the plungers in them to push out the air until they were solid. I like my overkill for assembly and first start. It's only overkill until it isn't.

A completely primed motor makes for a nice first start up

Unfortunately the VLOM got thrown out a week or so ago.

CHECK PUSHROD LENGTH! THIS WILL TAKE A BIT OF LEARNING BUT WORTH IT. WHEN CAM, SPRINGS, LIFTER TYPE ETC CHANGE IN THIS CONFIGURATION THE STOCK AFM PUSHRODS MAY BE TOO LONG AND CAUSE ISSUES OBVIOUSLY. EVEN IF THE 7.400 SHOULD NOW BE 7.375 OR WHATEVER YOUR IDEAL NUMBER IS AFTER USING ADJ PUSHROD LENGTH DETERMINATION PUSHROD' YOU JUST MAY BE SURPRISED!

Yup! Oil and fuel systems were both primed. I videoed my first start after the refresh. It fired up immediately and didn't make a single tick. You'd never know it was torn apart and not ran for three months.

the ticks make my heart flutter tho

and when they go away its that much sweeter

Word. I changed the cam, had the heads shaved, installed new valve springs and lifters, had spring heights checked and adjusted and used thinner head gaskets- all of which affect valvetrain geometry and pushrod length. The $28 is a bargain for the Comp 7702-1 and the fun that comes with using it!

I can only dream of having a 94mm turbo to drown out anything I didn't wanna hear

Ugh...I had a similar problem after my first attempt at the cam swap. Turned out to be a failed lifter that started wiping the cam, but we never determined the true cause. Sounded like a loud chirp when it was running but the engine made great power. Must be something else happening with yours if it's not making good power. I agree with the others here - time to tear it down. I'm feeling your pain, brother!

Did you ever find a solution to your problems I’m having the same issue

Yes, it was poor quality lifter trays allowing the lifters to twist in the bores.
