Vacum pump!

Eco Tuner

Very common when we see the cheap blend oil used VS a full synthetic. As the chain stretches it climbs up the cam gear teeth as the gears are a low profile design, so it takes very little stretch to create an issue VS old higher tooth designs.


Also, the tensioners, even though spring backed for some tension mainly rely on the oil pressure to maintain proper tension so as the bore/piston wear oil bleeds past and they cannot hold proper tension so you hear the chain "slap" around....and that wears the guides out prematurely.

Never ignore any noise like this and a good Ford tech can diagnose properly.

First, I have only used synthetic from day one and I change it per ford's schedule but I do think their schedule is too long. [MENTION=75988]Cord[/MENTION]. I'm not sure how they came to that conclusion.

Your doing your best then. I also dont agree with that long of interval...but based on oil analysis they have a decent argument for the length. I just cant do it my self. Good luck!

I read a report somewhere that said the oil can take the long intervals but the timing chains can't take the Carbon build up in the oil. It said the Carbon particles wear the links in the chain... especially in overhead cam engines because the chain is so long it shows up more. The report said 5000 is really as long as you should go.

Most oil analyses I've seen show the oil is often marginal on the ecoboost by 5000 miles regardless of synthetic or syn blend. Though not always. I suspect a 5000 mile interval with blend may be better than extended with synthetic based on reviewing oil reports on bitog.

But I'm still doing full synthetic and 5000 mile intervals since I haven't yet done an oil analysis to verify my truck.

Yeah I think a quality synthetic or synthetic blend is the way to go no matter what. Ford does have a spec that the oil is supposed to meet and I'd make sure whatever you use at least meets that. Also a quality filter is a good idea as well as if it is carbon particles causing wear the better the filtration the less they should be floating around.

Duty cycle also plays a role in it as well - if you primarily do lots of highway you're probably good with going by the light. If lots of short trips, especially in the cold, probably good to change it early.

That being said if you want to run synthetics and have a WalMart near by the you can do your own change with Pennozoil Platinum (one of the top rated synthetics) with a Ford filter for around $40. Cheap insurance and cheap price for a great oil!

Full highest quality synthetic for sure an don't be afraid to up the Wow factor with 5W40 for hot weather in broken in motors ( that oil pump is broken in ) if you are asking the EB to perform as a diesel does. It is now available in some areas. It only is a miniscule loss in miles per gallon. U are now protecting those hard working parts to the max.
Would just use 5W30 if you putts around and seldom actually work the vehicle. But if you go ball to the walls tow go for it.

Correct. Since the EcoBoost PCV system is a design that can only work properly for a NA engine, not a turbo application the PCV only evacuates at idle and low RPM's so the abrasive soot, carbon particles, water, unburnt fuel, sulfuric acid and other contaminates accumulate in the oil so interval is critical as is correcting the flawed design of the PCV system so it evacuates at all times like Rhineland Ford determined in their testing:



The GM 3.6L DI V6 engines have a similar issue that wasn't corrected until late 2013....those engines from 2008 through 2013 have the same premature timing chain wear as well. (do a google search on 3.6L timing chain failure).

There is no proof to any of this. No oil analyses from properly running engines to back it up. All analyses show normal particulate matter, low wear metals, and for the most part low fuel dilution.

Oh, and you don't want much PCV evacuation at idle or you will end up with idle quality issues. Nor do you want it at low RPM's either. http://www.aa1car.com/library/pcv.htm

I have a hunch Ford knows what they are doing with the PCV system as it works fine on the well over 600k Ecoboosts out there. No sludge buildup, no idle quality issues, or any of the hallmarks of a poorly designed PCV system.
