Ford must have taken a design cue from BMW.
We have a 2007 328i that developed a very small weep from the valve cover gasket on the engine...right on to the exhaust manifold. Smoke rolls up from the hood when at a stop light, and the cabin intake sucks it into passenger compartment. The car has been renamed "Stinky". Valve cover gaskets are cheap, right? The bill to fix the oil leak $1300.
The engine bay cowl in front of windshield has to be dismantled to remove the vavle cover because of engine set back. That's additional to the engine work.
We had the work done, anyway, a year ago. $$$ Now it is leaking again.
I'm not impressed with BMW's "superior" engineering.
Looking more and more as the ultimate fleecing machine.
