Lot of knocking at times. Gets very loud. Symptoms say lifter. Using a quart of oil every 1000 miles or less.


GM motor not an option. Those on build to order. Friend of mine runs parts for Chevy dealer. 4k plus months to get it.




I called and spoke to the mechanic that our family uses to see about replacing my 05 1500HD 6.0 motor (275k). He stated whether I used him or someone else to only get a crate motor form GM. He quoted me $5900 for the swap out.

Sounds like you have an oil pressure problem. My lifters start ticking once it warms up and thats when oil pressure drops.
