Ticking Sound

[petethepug]

2012 YXL. Still have any coverage on the 3yr / 50K service contract?

1st check for exhaust gasket leaks. Have it checked ASAP if you can have coverage on the S/C.

Is the AFM turned off with a module yet?

The contract expired, and I had @BlackBearPerf tune it and turn off AFM.

Sorry for the crappy video.

Years ago I had a Suburban that developed a ticking noise. Noise went away when I replaced the spark plugs and wires.

The sound is not as noticeable anymore. Am I on borrowed time?

If it comes and goes, that could be valvetrain sludge, rotated lifter, or a loose rocker... Maybe even a broken valve spring that made its way into the valve cover area.

I would start just by doing the easy stuff, pull the valve covers off, and give her a good inspection.

@itsbo1313 My lifter sound would come and go, sometimes it gets stuck in the wrong position and sometimes it can sort itself out. I would say that you are on borrowed time, it might last 1 week or 1 more year. Start making a plan for when it happens.

I had that noticably in my dads 07 flex 4x4 and it went away immediately after i put new spark plugs and wires in... But now i am wondering if it is the lifters... Please keep us posted on what direction you take and what comes of it ie (what you find out) as this area is my next one after i get the radiator and all its close buddies replaced.

Ditto.... Did it ever come back or did you have to do something about the exhaust or lifters later by chance?
