My 6.2L GEN 1 raptor has a little valve tapping that I hear when the windows are closed…. I run full synthetic and some lucus oil additive … should I run a little thicker oil than the 5-20 on the cap ?? The engine does have 226,000 miles but from what I’ve been told everyone says I should get 400,000 out of this engine …. I run full synthetic , K&N oil filter , premium fuel , and cleaned throttle body and mass air flow sensor …. The valve tapping isn’t super bad but I hear it with the windows closed …
