Once again sho pics, I want to see RWD EB pics, the heads are supposedly different. I am not saying the results will differ, i just want to see F150 evidence.

 

When you pressurize the engine, going into boost, oil goes some where and generally into the intake tube. This happened with my powerstroke diesel truck and my Lightning (had turbo) and my duramax diesel truck along with my 7.3 Excursion.

I suspect my Ecoboost will do the same thing.

Just except it!!!!!

 

Accept

 

you first

Show me pics of these 'supposedly' different heads.

Y'know - you should at least be consistent - up at post #100, you derided, and I quote: "I heard from a guy who heard from a guy...." .

And now you have these alleged "supposed" different heads. Which to me, equates to the same old thing.

Show me the beef!

Here's the deal - it's NOT the difference in heads, it's the Fundamental Architecture. The data presented transfers - to a LOT of different platforms - there are FAR more similarities than differences...


For some inexplicable reason, this image keeps popping into my forebrain - sorry, I can't help it!



Trust Ol' Mamma Nature to have an answer for ever'thang!

 

My source to the difference in the FWD & RWD versions of the 3.5 EB.

"The truck version of the 3.5 EcoBoost engine shares almost nothing with the front-drive version, with a new block, new camshafts with twin independent variable cam timing on both intake and exhaust cams, smaller Borg-Warner turbochargers replacing the larger Honeywell turbos, a Nippondenso direct-injection fuel system instead of the Bosch system, new cylinder heads with tumble ports, new cast iron exhaust manifolds in place of stainless steel headers for added durability, a new cam chain drive, new oil pan, new water pump, larger intercooler and intake manifold.

In essence, a whole new engine with the same name and horsepower rating as the front-drive engine but little else in common."

Quoted from The Detroit Bureau. I'm using the mobile version of this website so I cant display a link, but I'll put it in here anyway. http://www.thedetroitbureau.com/2010...0-ecoboost-v6/

Hey it worked anyway. In anycase I get that this is a DI engine and this system has a history, I still want to see some pics of an F150 showing issues, not the Taurus.

 

Fundamental Architecture.............Get it?

 

Getting chippy in here.....

Didn't read the last sentence of my post, I assume?

 

They did, it's built into the valve cover so the oil drains back into the engine. On 2 of 3 trucks checked in this thread it seems to be working since the PCV lines are clean. I also checked at FastPartsNetwork.com for the valve covers on a 2010 Taurus SHO and a 2011 F-150. They have a much different price but sadly that site no longer lists the actual part number. However, it can be safe to assume that since the prices are over $100 different they are not the same. So, the basis for all this debate is fundamentally flawed. The truck does not have the same PCV system as the car motor that was used by BG to create an showcase for their products.

Take it for what you want but the manufacturer says they have made changes to their product to address a potential problem; another company uses the first product to showcase the items they sell and then extrapolate the data to the revised product without rerunning the tests. Who do you believe? Both companies are trying to get your money.

 

I thought I'd deliver my $.02 on this seeing as how I went from a 7.3L Powerstroke to an Ecoboost.

Personally, I'm not worried. Those that are making a stink about this probably haven't touched a 7.3L Powerstroke. The PCV on that vents right into the turbo charger's inlet and has little to no air-oil separation. Pretty much everything downwind except for the turbo impeller becomes coated in this lovely grime that only 15W40 can create. Diesels have NEVER had the benefit of fuel spray on the intake valves to keep them clean and the 7.3L Powerstroke has been around for 17+ years now. Surely someone would have had their engine crater because of this alleged problem. My F250 only has 130,000 on it and these Powerstrokes are known to last close to a million miles before needing a tear-down.

Really, I'd like to hear a good explanation as to why this isn't a problem on Direct Injected Diesels.

 

Sure would like to see some pictures of the installed canisters and a step by step procedure as to how to install them. I am an old novice and either need the detailed info or pay to have someone do the install for me.

Thank you

 

I went from a 6.0 to an EB, so I know about the turbo and the intercooler filling up with oil and rotting the silicone connectors on the tubes. There is a fix for that too, much the same as the EB oil fix. That is the sole reason I checked it out in the first place..........So, yes it IS a problem on the DI diesels.

 

The problem being discussed here is gunk accumulating on the intake valves. Not the intercooler hoses failing. That's almost a given anytime you have rubber coming into direct contact with motor oil.

 

The diesels have the same basic problems..........

And I AM aware of the discussion, I am the original poster for this thread. In addition, no one has mentioned an early teardown of an EB. The problem is fuel mileage and efficiency. The 7.3 has never been nor will it ever be an efficient engine in stock form, lots of cubic inches and little power to show for it.

 

New here.
I just did an oil change. First one I did myself. After reading this thread I will run half a quart low. Or in other words, I just put in 5.5 quarts back in. I find the dipstick very hard to read after it has been running. I rechecked it this morning after it settled for the night. It was easier to read cold and gave the correct reading. I had just put in 5 quarts yesterday and it was at the bottom of the safe zone. I figure running right in the middle of the safe zone will allow for expansion and back pressure. I used Mobile 1 and a K&N oil filter.
Last time I changed the oil at Kwil Kar and they looked lost trying to change the oil. I later checked the oil and It showed oil way up on the dipstick. I took it back and they said they put in 6 quarts like it says. They drained some oil till it was it was under the line on the dipstick. After doing it myself, Im glad I did and will continue to do it myself from now on. The rubber plugs were gone. I dont know if they left them out or the truck just didnt come with them. the bottom of the cover where you drain the oil was a mess. Lots of oil all over everything. I could also be that I have a leak on the tranny. Ill have to get it checked because this truck has no dipstick for the transmission. I have been noticing the transmission hard shifting from time to time.

 

You in the correct thread?
