VeeMax Posted July 5, 2011 Report Share Posted July 5, 2011 When I start my truck sometimes I here a lifter being a little lazy for a bit, it ticks for 15-20 seconds. So it sounds like it needs new lifters. If I do that I should go ahead and have a cam put in. Is there a shop in the Dallas area that can do that for me? I don't think I want a dealership doing that for me. Quote Link to comment Share on other sites More sharing options...
Fireman31 Posted July 6, 2011 Report Share Posted July 6, 2011 Can you get a video of the noise? These trucks are prone to piston slap which is quite common, that may be what you are hearing...... Quote Link to comment Share on other sites More sharing options...
VeeMax Posted July 6, 2011 Author Report Share Posted July 6, 2011 I will try to get a video. Its so seldom it will be difficult. Piston slap? That sounds like an engine death sentence... Although it sounds like a lifter/ rocker tick to me, but I'm far from an expert. Quote Link to comment Share on other sites More sharing options...

Bad Bowtie Posted July 11, 2011 Report Share Posted July 11, 2011 NBS- 6.0L V-Max That said, I know the NBS GM trucks (with AFM) have a problem with failing lifters. But a V-Max doesn't have that feature, correct?? Quote Link to comment Share on other sites More sharing options...

Bad Bowtie Posted July 13, 2011 Report Share Posted July 13, 2011 (edited) I do believe mine has the afm. Switching to V4? Yes, it should show "V4" up on the dash when u are coasting downhill, or along a flat stretch of road. If so, throw in a fresh new set of new lifters and an oil change with a good oil filter....

VeeMax Posted September 1, 2011 Author Report Share Posted September 1, 2011 Update, I changed the oil to Mobil One and Mobil One filter and the seemingly lifter ticks at startup went away. Just thought I would share that. Quote Link to comment Share on other sites More sharing options...

Just thought I would share that. That's great news, i would blame the oil filter for that, what filter brand did you use before the Mobil 1?

I'm not sure what filter was on there, I had just purchased the truck( I had it just a few months). The filter may have restricted the oil a little too much huh? Well so far is has been fine and on the 2nd oil change of the Mobil One. Going to put the 6.0 to the test tomorrow. Hauling the atv's to the Cali sand dunes from Dallas, about a 3000 mile round trip.

05VHO Posted November 9, 2011 Report Share Posted November 9, 2011 You should probably still get a new cam! Quote Link to comment Share on other sites More sharing options...
