They build these engines everyday, having to wait 7 weeks for parts doesn’t follow conventional logic. By getting everyone to wait a month or two for parts it discourages others from dropping their trucks off and inches the low mileage users closer towards the end of their warranty periods down the road. If there is 60 months of warranty and trucks are sitting an average of 6 to 7 weeks that means the truck is down 3% if it’s life, that WILL affect some especially considering how low mileage a lot of Raptors end up being.
They are playing the EXACT same game GM played with the LS7 engines in the Z06s. When companies play such games it solidifies my opinion on three things, they know about the problem in a major way, they don’t have a solution and it affects or will eventually affect all engines.
If I had to nail the initial problem I can’t say it’s a bad batch of phasers. I think the system is just too high of a volume for the oil capacity of the pump. It lends me to wondering if the phasers are allowed to run in said condition for a bit, the oil is effectively bypassing through the phasers, is oil pressure (the driving force) being robbed through the bearings? During this time period tolerances are expanded elsewhere and even with a nee, nice tight sealed phaser the stock oil pump can’t handle the loss of tolerance control that occurred in the first place. Or... the phasers have nothing to do with it at all. It’s simply a loss of tolerance control elsewhere (high lower end and/or head temperatures) and a slightly worn but still in spec phaser just masks the true underlying condition.
I have an entirely new timing system and my truck rattles like it did at 5,000 miles and WILL get to the place it was at 24,000 miles. It’s a function of time. What I would like to see it s black stone oil analysis of every truck that has a rattle. I did one and lead was high out of spec.
