When I first start my Camaro in the morning it runs great. But after a while of conservative driving, it warms up to over 220F and the oil pressure drops to under 30 at idle. Also, the engine tends to idle rough right around 550 rpm. Is this normal? I've changed the thermostat to a 180 unit, and also flushed the radiator, changed the temp sending unit,and made sure the fans worked. I also checked timing, because I heard that a lean condition can cause over heating as well.
Does anyone know the avg. engine temp for a 305 LO3 engine? Also, what is the avg. oil pressure for the same engine using 10w30, when the engine is warmed up?
