Lost compression in Cyl.# 7 only
Has anyone experienced this problem?
Went into limp mode!

If I were a betting man, I would say the #7 DOD lifter failed. Common problem.

Well, I guess with all the gas I have saved with DOD there should be more than enough to cover the repairs!!
Do they change all lifters on both banks?
Sounds expensive??
Is there a permanent fix, or are we looking at this happening in another 80K miles?

Interesting I thought they had these somewhat fixed, especially with the gen 5. I assume it's a gen 5 in 2016. I had similar problems on my 07 but they had a design flaw, well the entire concept is a design flaw as far as I'm concerned.

Have you pulled the valve cover and inspected things? Maybe pull the rocker arms off and make sure nothing else is bent or broke.

You can swap use a DOD delete kit. The heads have to come off if it is in fact a dead lifter so might as well when you are in there.

The brand new 18's are doing it. It's strange that GM hasn't found a solution yet.

Yep - agreed on GM not finding a fix. I know the 07 - 12 or so suffered premature engine failure issues due to loss of oil pressure when the lifters died. I guess at least now you just lose compression in a cylinder?

DOD kit is the only way to go, then getting it flashed to disable it in the ECU as well.

I might have to buy a Range Disabler for my 14, I dont want to deal with this crap again.

Rich84 · 03-24-2019, 08:05 AM

I am using one with my 2016..gas mileage is about the same. Like the way it drives much better.

Just disabling the system isnt a foolproof method, since you still have the DOD lifters in the engine which is the part that fails. Just because they aren't operating doesn't guarantee they will not fail.

I deactivated the DOD on my sons truck but the oil pressure is something I always worry about because I know its not if a lifter is going to fail its when.
We plan a DOD/VVT delete soon!

sprint_9 · 03-25-2019, 07:11 PM

I agree its not fool proof, but by not operating them the failure rate goes down considerably with minimal effort. The part that usually fails is the pin, either by wear or by being out of time. Keep it locked and two of the main problems are no longer issues.
