Own from birth 2006 GMC with utility body. All services and such performed by same mechanic. Called to inform him of oil pressure steadily declining to below 15 psi. Brought truck in, replaced obvious sending unit, drop transfer case to drop oil pan to check oil pump to eventually removing engine to discover spun cam shaft bearing in two locations. Is there no tolerance to saving the block? Besides scrap metal. Losing 900.00 for a core adds insult to the injury being that all maintenance was done. IS this the norm for the 6.0 liter engine?
