    Another ford question

    2012 ford escape 2.5 engine. Recently had a problem with the throttle body too many miles to get replaced free it was a flaw in part so I bought a new oem part and installed. When I removed the old it was nasty. After installing the new it ran good but is starting to show the same symtoms here is the question is there any way to clean the more than likely build up on the top of the engine. Perhaps seafoam c16 in the oil or marvel mystery oil change the oil add and run few hundred and drain? I am worried I will loosen some crud and clog the oil passages. I was also told that the oil was changed at the local lube so I don't think they used the best oil. Manual calls for synthetic or synthetic blend. Thanks Rick

    A lot of people swear by BG products for cleaning throttle bodies, intakes and valves.
    One of their products is introduced into the inlet side of the engine through the air intake or the pcv port. Product is added to motor as it runs.
    There was a recent post touting these products, I'm sure we'll hear from them shortly.
    If it were my throttle body, and dirty, I'd pull it off and clean it thoroughly in a parts washer followed by carb cleaner and compressed air.
    To safely clean internal oil galleries with little to no fear of knocking chunks loose to clog the oil pump screen, I'd suggest more frequent oil changes, every 1000 miles or so. When I get a "new to me " older vehicle, I like to do oil changes every 1000 or so till it cleans up.
    If your throttle body/ intake is getting dirty quickly, make sure your pcv and egr is clean and in good working order. Might have oil control issues.
    Hope this helps.

    I changed out the throttle body but I have never seen one that dirty and it starting to exhibit the same hesitation it had with the bad throttle body. I did reset the pcm and pvc valve is clean car has 76,000 and was driven by a 78 year old woman in NYC. If the egr was dirty wouldn't I pull a code. I gonna try the oil change and add a shot of marvel mystery oil and change at 1000 miles. On the old cars I would add transmission fluid to the oil run hard a couple hundred miles and change the oil but not with these new motors.

    I had issues like you speak of with oil getting sucked into throttle body. The only thing that worked was running the oil on the lower side of the dipstick. Something about leaving a little more room in the system? I do not know, but it worked. Also, if that vehicle was only driven by an old woman, you might want to get it out on the highway and open it up. Likely she never did, and it would probably be good for it. Change plugs after.

    Or just add a draft tube to the engine

    What was the "flaw" in the original throttle body?
    Oil vapor and combustion deposits seem to be the most likely culprits of throttle body/intake contamination.
    EGR and PCV are capable of introducing these into throttle/ intake.
    EGR usually comes comes on after warm up.
    I know egr will set code if insufficient flow is detected, but does it set a code if stuck partially or all the way open. Perhaps stuck open or partially open, allowing rich, warm up fuel trim sooty deposits to flow through? But not enough to set misfire code or detectable rough idle?
    I'm no expert, just bouncin' ideas around.
    78 year old woman?
    Maybe a good old fashioned heavy footed highway carbon clean out is in order!
    Good luck.

    One time repair program? Hopefully with an updated part.
    After that you're on your own?
    Improperly sealed throttle body motor,
    Wouldn't want to put that one in the parts washer!
