Hey folks,I got 03 ranger 500 that started acting on me couple weeks ago,after I started chasing rabbits in the fuel/electrical departments i finally popped the valve cover to discover that the camshaft is worn out to the point it was round at the exhaust side,so changed that with used but good oem one from eBay and brand new oem exhaust rocker,got it all together,changed oil filter with oem,also got some stp oil treatment,as far as for where the shavings are I don't know,I chopped the old filter didn't seem to find it that bad,I mean it was sparkling but not terrible,drain plug magnet on the oil tank had a few on,anyway,I rigged a oil pressure gauge and if I go full throttle down the road I get 28-30psi,when I drive at real slow speed I get 10-12,what I am confused and concerned also is idle pressure,when the oil got hot I got down to 2psi and I can't find anything that says what that should be at, everything I read says at 5500rpm 12psi min-30maxAny feedback appreciated
