It's time for a long-overdue update. Matt Phelan just paid us a visit on his cross-country road trip to diagnose excessive exhaust smoke and some severe shuddering when the torque converter is locked.
He ended up pulling the driver's side valve cover (bank 2) and discovered... you guess it... FLAT CAMS! The intake lobe on the 4th cylinder from the front is almost completely flat and the intake lobe on the 1st cylinder is about half way flat. Based on MAF readings, bank 2 is about 1.5 cylinders down compared to bank 1 (350 vs 250). We didn't pull the valve cover on bank 1, so it's possible that its cam is also wearing.
This is the end of the road for the mighty V10. We don't want to do a $3,000+ cam job only to find out that it also needs two turbochargers and maybe a transmission. We'll be trading it in for a new vehicle in the near future.
It's been fun. I don't feel too bad since I knew about the PD cam problems and other V10 problems prior to buying this vehicle. We've had a lot of fun tinkering with it, doing some upgrades and fixing some problems along the way, but now the time has come to move on.
If anyone is interested in purchasing the truck, please send me a PM. $4,000 OBO is probably a good starting point. It runs and drives, everything functions as expected and there are no codes in any modules except for an intermittent implausible MAF code for bank 2. The code hasn't triggered a check engine light yet. The vehicle comes with two sets of wheels - the stock Fatboys in good condition with relatively new Pirellis and a set of Kartoums (rare!) with worn snow tires.
