First off let me say what a great site this! there so much info here, that i have less understanding about oil then what i thought i had.
my question is about the oil for my 04 f150 with the 5.4 mod
here is a little back ground (what little i know) on these motors, they have Variable cam timing,vct. now some of them at idle will tick or knock like a diesel when warmed up. Ford use to change the cam phasers but has long since stop and proclaimed the noise is normal. from what i can fined some of these trucks make the noise, some don't, some have made this knocking noise forever with out a problem and some have lost the cams some. Ford biggest claim for this is not running mc filters
In april i pickup one of the trucks, i did not hear the noise when i bought it, and took it back as soon as i heard it.
the dealer had the shop listen to it and said that it normal and suggested running a engine flush at the next oil change as this may help quiet down the noise down. This noise at idle is so annoying that with only 1500 miles on the oil i put some seafoam in the oil and changed it with 1800 miles. i put in mobile 1 5-20 (recommended wt) and mc filter(reommended filter). The old oil did get dirt after the seafoam was added but not very. i look down the oil fill afterward and everything was bright not even any varish to be seen.
Now does any one have suggestion on what i run for oil, oil wt,or additive that can quiet it down. The truck runs fine from what i can tell. i can replace the cam phasers at the tune of around $2k. the truck has 115k miles i only but 8-10k miles a year. it get around 500 miles or less a year towing i will change oil in the fall and spring around 5k. i always had good luck with mobile 1 in the past (most of my cars/trucks make it well over 200k miles and i retire them for other then motor reasons).
sorry so long really what to give as much info as possible. thank for any help
