So after dumping a bunch of money into a 95 blazer it was running great.
Today the oil pressure dropped to 0. Turned off and let cool off. Is full of oil. Started cold 50 psi, let it run 10 minutes and it holds so I head home.
About 5 miles the oil pressure is 20 at 2000 rpm. Get it home and oil pres is now 10 at idle and lifter or bearing tap. give it a little gas and oil goes up and knock stops, then back to 0? Figure I'll drain the oil tomorro and look for metal shavings?????????
