6.0 ENGINE KNOCKING
First, thanks for any help or advise in advance.
I have a 2006 f350 harley 6.0, 140kms,arp studs,egr delete,predator tuner(on tow only,40 hp)studs and delete kit was done at dealer 3000 kms ago.just run out of warranty on the 22nd of July.
First,truck runs perfect but has a knocking noise after engine gets up to temp.
truck idles fine with a very little popping noise kind of driverside by firewall.
When towing or while truck is hot under light acceleration there is a knocking noise on the driver-side,just after the injectors start to open(idle no knocking noise)went 400kms(with trailer) and was knocking quite loud under stop and go traffic.sounds like one cylinder and is consistent with rpm's.
I think it is a injector but no codes on my scanner and the truck runs perfect(except noise)16 mpg towing with trailer.
symptoms=first start up even 35 deg days white haze coming out of exhaust,smells like unburnt diesel(burns eyes).until warmed up,then no smoke.
knocking noise most noticeable under light acceleration.
when i restart in the morning the noise is almost gone again until engine reaches normal temp and does it again.has been doing this for 5000kms,dealer says it is normal but i don't think so.they should come on vacation with me and here it(lol)they say it does not do it for them.
PLEASE HELP WITH AND ADVISE.
Sorry for the long explanation but tried to give all the truck details and symptoms.
