It is entirely possible, if not probable, that the powdered metal Oil Pump Gears are perfectly adequate for this application and not a single failure attributable to the gears occurred in testing or in service. They may actually be preferable to billet parts because of the precise manufacturing...
Engineering disaster? OK, as you wish.
Forums are wonderful things. Everyone gets to voice an opinion.
But one day in the not-too-distant future, we will know. If the oil pump is defective, Ford will quietly supercede it. Every Ford parts guy and all of us will know the truth.
And I will get...
I agree with your assessment of the high NVH associated with FPC engines.
I think Ford wanted to clearly differentiate the Voodoo engine for marketing reasons, adding uniqueness and perceived value to the GT350. They succeeded, big time.
However, these OEMs due brutal durability testing on new...
It is possible that your oil pump is failing. But if the pump can achieve the normal 75-100 psi when you rev the engine, its probably not the pump.
Low oil pressure at idle is usually caused by excessive clearance somewhere in the system, like a loose or worn cam bearing, failing rod or main...
Yikes! I'm not agreeing with what Ford is doing. I know that changing an engine is a royal PITA. What we don't know is way more than what we do. Are the gears the culprit, or just a consequential damage? Are there lots of engine failures, or just a handful?
The current oil pump gears may be...
What Ford prices their engines for and what they actually cost Ford to make are two very different numbers. I stand by my $5k cost for a long block.
My close friend works at BMW motorsport. They charge $24,000 for a 2015/2016 M5/M6 long block. BMW manufacturing cost is $6600. Jus'sayin'.
But...
Sheesh. Powdered metal is not the ideal material. But It has very high tensile strength and wear resistance but not impact resistance. It is not ductile, but brittle. You are focusing on the pump as the cause. I suspect Ford already knows the cause and also knows pump gears are not the issue...
Not defending Ford. Just stating a fact. Do the math with your numbers. Ford spends $50 on an oil pump. Your $500 pump is $450 more, times 10,000 cars. That's $4.5 million in extra cost. Ain't gonna happen unless they lose a lot of engines and find the pump is the cause. It's a business. You're...
Powdered metal parts can be very strong, but they are far less resistant to impact damage, as much as 50% less than hardened billet steel.
Ford uses these parts for cost reasons. Powdered metallurgy allows for net shape manufacturing with little or no machining required. It saves a lot of...
I'm a very happy GT350 owner and I drive mine every day. BUT:
In my opinion, Ford has plenty of development work to do on the existing Voodoo engine and GT350 platform.
The engine's part-throttle piston rattle is terrible. Low speed torque could use some improvement. The shifter is nowhere near...
Mechanic here.
A cylinder leak down test will not, by itself, diagnose valve seal problems.
However, a bore scope can "see" burned oil contamination on top of the piston.
Assuming that the cylinder leak down is normal (no ring seal problems), then the valve seals on that cylinder's intake...
