Ok, so last week so I drained out my synthetic oil fresh in December with 2500 miles and put in some fresh mobil 1 due to my being unhappy with looking at the big ugly Mopar oil filter my former mechanic installed during that oil change right after I bought the truck (next I am going to changeover the toothed aftermarket belts he installed for oem since they are deafening me). I put in a small OEM 20004 filter. Everything is fine but now I have a slight intermittant start up rattle where previously I had none. It lasts for under a second and almost sounds like the starter is still engaged. Is this the famous start up rattle and, if so, is it normal to get it with the small filter?
