Try an oil flush to clean up your oil light flickering at ldle. I could idle my 6 down to where you could count the fan blades and my light never came on. I like Sea Foam for a flush, throw a can in oil and let idle for 60 mins and change your oil. I run 15w40 DIESEL OIL in all my older stuff and it really helps keep engines clean and helps with oil pressure.
