It is a 2016, started after about 8,000 miles, finally fixed at 15,000 miles with new driver side cylinder head. From what I've been able to find out, Ford has had some valve seal issues on engines made in late 2015 into mid 2016. Not a bunch, but enough that they are aware of it. Typically...

Ford had some heads with bad valve seals come down the line. Usually on the driver side head according to the factory techs. Valves can leak on otherwise low mile and healthy engines. This was found after complaining about smoking exhaust and I had the dealer check the spark plugs.

Not sure under Canadian law, but under U.S. law the dealer would have been full of horse poop. They can only deny warranty work, if the modification was directly responsible for the failure. At least under U.S. law, and I imagine Canada is same.

1. These cars suck a LOT of oil up through the PCV valve on the passenger side. This is the one that see lots of vacuum pressure at light throttle. Put one of the aftermarket oil catch cans on that side. 2. Mine was recently doing the same thing and it turned out I have a bad valve seal. Dealer...

There is a short somewhere. Friends F150 started doing similar odd things and would not stay running. Was found be to a short in some fog light wire harness. Dealer time..

Probably just a little piston slap. Take it to the dealer, see what they think...

Sure it's possible. As far as the efficiency difference, in the grand scheme of things it is probably minimal but would be measurable. In a world with people comparing dyno numbers to +/-10hp differences and track times in the 1/10th of second though it would make the difference between...

Are you talking about the intercooler flow ? If so, people use vertical flow intercoolers because you can fit more flow passages in the same space, which leads to less restriction. Less restrictions means the turbos dont have to work as hard, which means they produce less heat, which means you...

I fixed it for you.... :thumbsup:

4 months worth of 2017's still sitting on dealer lots .... Ford Inventory Numbers 111 days’ supply of unsold Mustangs 87 days’ supply of Fusions 103 days’ supply of Transit vans 162 days’ supply of Lincoln Continentals

Nope, just some Roush axle backs and a Magnaflow resonator.

#8 cylinder spark plug was so fouled with oil that the dealer tech was surprised the engine was running as smooth as it was. They are going to tear the engine down next week and see what's going on. Not good to hear this, but at least it confirms what I already knew, that something was really...

I would love to see someone making a twin kit using the Borg Warner EFR turbos with integrated waste gates and and recirculators eliminating the need for external W/G's and BOV

So I have a 2.9L Whipple kit I took off my 2011 S197 and boxed it up and put it in storage when I sold the car. Anyway to make a S197 rear inlet Whipple fit on our S550's ? If Whipple hadn't changed the lower intake so much for the S550 kit I would just buy a new head unit, but that wont work...

So the car has been back up at the dealers for last couple of days. After talking with Ford they think it may be a bad valve seal or valve guide. A batch of 2016 Coyote motors have been popping up with valve issues, usually on the drivers side head, according to the dealer. They are going to...

New ECU's record if tune has been altered, even if it's reverted back to stock. It keeps a record of it in there.

Mine too. Indexing the driveshaft 180* helped a lot, but it still has a mild vibration around 55mph. Before indexing it was shaking so bad between 60-75mph that the rear view mirror looked blurry.

It's not so much the consumption that threw up the red flag for me. It was the giant FOG BANK of smoke coming out the tail pipes every now and then. It doesn't do it all the time, but when it does do it, it's big, and it's definitely oil smoke, not coolant or condensation. Oil consumption and...

Break in of the motor was done normal. Nothing hard or high rpms for first couple of thousand miles. Near same story as Vato. Always taken to the dealer for oil changes. I bought the Ford Extended Service Plan. Take it in for 2nd oil change at 10k and complain about clouds of smoke. No oil on...
