had head gaskets done on the 03 ram. ran great and still runs ok, but recently did an oil change
and then at idle, the idiot guage drops and the check guage light comes on--then goes up right away...first filter after the HG job was a purolator classic, now I used a fram ph16 and this starts.... oil I drained had 1800 miles an looked normal but very dark---nothing unusual. I drained early due to contaminated oil prior to repairs....tomorrow I am going to replace the pcv valve and oil pressure sending unit.... my question is could this fram be a problem? I had a Durango with the same engine and never had this problem---
