I know Cummins is #1 for diesel engines. I've seen some Cummins 4 cylinder diesel conversions on Youtube.Actually Ford does not make the PowerStroke, Neverstart (Navistar) did until 2011...
And I know many guys running Ford trucks with Cummins, very popular re-power when the stroker goes belly up...
Dealer called and the van is done. The guy drove it and said that those front brakes really were bad! The replaced the rotors and pads under warranty. He said there was a PCM flash for the Remote start intermittent problem, did the ignition recall and they ordered a part to fix the sliding door inside panel touching the fender. I'm excited to see if it drives and brakes smoother now.
