See i dont know which one i should vote on, i had a motor seize .8mile from the truck on its first ride cause the dealership that set it up didnt bleed the oil pump and didnt pre-mix the tank when they told me they did pre-mix it! if i had to choose one id say number number but i just dont think thats fair to purpose of the thread because it was not AC fault. But now with new motor not an issue to speak of, she has been running solid!
Well... I'd say the 12 failures & the fact that I included the 2010 motor here are the only thing keeping the poo motor even in the same realm. As it sits, with WAY more average miles, and a whole extra year for failures to show up, the pro motor is still showing about double the failures. Dealer setup aside, and comparing miles to miles I think it's more like 4x the failures at least.
