I got a 2016 F150 with a low engine knock when the engine is at operating temperation at idle only, its seems to come from passager side. The engine does not use any oil and there is no loss of power, does the gen 2 engine have the high pressure fuel pump on the passnger side head. It is a little annoying, any insight would be great, thanks.

 

2018 was the first year for high pressure fuel system on 5.0
