Older EcoBoost engines DID have an auxiliary vacuum pump. Some were electric, some were mechanical.Groover wrote:
I do know that both of my Ecoboost engines have vacuum boost for manual brake applications with electric braking for computer activated brake situations, like collision avoidance or ABS adjustments. I would bet that you still have a vacuum canister right behind the master brake cylinder.
Mine are full electric. No vacuum chamber on the master cylinder. This is pretty new. Only out for a couple of years. The whole assembly is made by Bosch.

bad luck for early adopters. never seemed practical to me. too much heat and stress for small engine.

Name the engine and I’ll point you to a post about someone that had a major problem with it; that doesn’t make it “impractical”.

Oh yeah, the electric vacuum pump seems to be there in case you need to apply the brakes while the turbo charger has the intake manifold pressurized. So it connected to the manifold via the brake vacuum booster and debris can be sucked through. Apparently, failures of the electric pumps are not uncommon. The amount of damage that my daughter's truck suffered is. That is what the mechanic told us but based on some other issues that have come up I don't put a lot of stock in what that guy told us but the bottom line is that I still need a good engine.
Yes, vacuum can travel from the pump to the intake, but I can not understand the failure mode of the pump that could damage the engine ?
FYI, my 2022 F150 2.7L EcoBoost has electric power assist brakes and electric power assist steering.

I don't believe that towing or running the engine heavily loaded has much effect other than the increased RPM increases the number of load cycles per mile.

[COLOR=]I guess that you missed the part that we were in the process of moving 1250 miles and were slap up against the deadline for the move. Fighting the dealer from this far away would be very challenging. We did get a $4,000 refund from the credit card company though.
Supply chain “issues” are no secret and they weren’t 6 months ago either. Whether actual or just an excuse.
I spent 2 days on the phone trying to find a long block or good junkyard engine with no success. I did speak with Jasper and Fraser amongst others and neither of them would even give me a rough estimate of when they would have one ready.
Anytime you just sit back and “hope” something goes right the chances of that happening are diminished.
I was on their tails the entire time. Who do you think prompted them to push it with Ford and then order a different motor?
I understand how it’s more complicated when one doesn’t understand vehicles but half a year to fix a car is just not taking control of the issue.
I am sure that you would have gotten it done much faster.
