rgr71 Posted October 2, 2012 Posted October 2, 2012 08 gmc truck 4.8, many months ago the camshaft & lifters failed, parts were replaced. drove to school this morning and it ran great, started it up after class and had a very loud clacking, then oil light turned on w/low pressure message. Oil level if fine, i have a bad feeling that the bearings are shot, pretty sure the oil pump is too. i bet i have had metal shavings in the engine from the cam/lifter failure causing the pump to quit. any one else had this?
