I have a 2006 F150 5.4 3v rattling and shaking excessively. I have installed two new cam phasers,two vct solinoids,two vct housings,flushed oil and installed motor craft oil and filter. This never happens if bank two vct is unplugged or in open loop. Monitioring vct's on ids only bank two is erratic. Any help would be appriacted. Also when I had vct housing off I blew regulated air through oil passage seems free.
