problem #1

Jun 012015

H2 Luxury 6.0L Vortec

  • Automatic transmission
  • 124,274 miles

Noticed loss of coolant, none on the ground. Loss of oil pressure and oil level was good. loud sounds like lifter knocking and slapping sound. Frequent oil changes showed severe sludge. Changed oil pump, problem continued. The diagnostics from mechanic state coolant is seeping into the engine. The engine needs to be replaced

Update from Feb 12, 2016: Problem started with massive oil consumption. Replaced the left valve cover (pvc valve location) obviously not the issure.
