Im new here to this forum and been searching without luck. Here is my problem
2005 colbolt 2.2 ecotec 43000 miles when bought 3 months ago now 48000 miles. No work ecept 1 oil change has been done since we bought the car
It developed a valve train noise, like a lifter tap in a v-8. No oil psi light on. Oil psi with test gauge at idle 75 psi at sending unit tap. pulled valve cover. litlle sign of oil on left side. pulled cam bearing caps. left cap on intake (front cam) wiped out. next one wiped to. they get slightly better working towards timing chain. Rear cam is just starting to get bad but not nearly as bad as from cam. Any thoughs on what causing no oil flow to head?
