    This type of thread ****es me off. Just because YOUR engine has a noise, does not mean ALL of them have a noise and nobody should buy the car. BTW somebody is feeding you a line of crap ford would not have us put known bad parts back into a car and ship it.

    There is nothing wrong with the 3.7 engine.. This motor shares a lot in common with the 3.5 that ford has used for quite some time.

    I have seen ford bend over backward to fix so called problems that are normal such as the f-150 transmission I swapped out about a month ago that even the field engineer agreed there was nothing wrong with it but the customer was a lunatic so we gave him a factory production unit to make him go away.


    so if anybody here is considering a 3.7 equipped ford you can buy one without worrying they are just fine and a very good motor.



    21726 exists but what are these tsb's those are not even in the format of a ford tsb.. please post the publication

    Yes, Ford can't make enough of these things to sell them fast enough. V6 Mustangs are being delayed because the F-150s are selling like hotcakes. If there was truly a problem I'm guessing that wouldn't be the case...

    I haven't run into any noises from 3.7's yet so I"m guessing its a rare condition.

    Need help with Ford tech explanation (3.7L related?).....

    Trinity is a 2011 V6, manual with 21K miles. Two weeks ago the check engine light came on so she went into the Ford dealership.
    Camshaft position sensor Bank 1 error message. Sensor was replaced and I picked her up.
    The next day, not only did the check engine light come back on, but it sounded as if I had put a custom ground race cam in her. Lobe, La, Lobe, La Lobe.....really spaced out and irregular! This time I put my code reader and it read Camshaft position sensor Bank 2.
    The cars idle was so bad and rough I had to have it towed to Ford.

    What I was told is that the cam phasers have apparently gone bad, which caused a horrendous timing issue that has possibly caused a valve (or valves) to drop into the piston chamber. Which has possibly scored the chamber wall.
    Thus, the dealership has brought in their "heavy engine tech" to pull the engine to inspect if a new block is needed. Ford is doing their part and I have no complaints about how they are handling it.....but I'd like a little more explanation. Can anyone help a girl out?

    Went down this road with a 3.8 Windstar head gasket. After some heated discussion, the dealer paid half the cost of the repair, and a year later, we got a check for the rest from Ford.

    At 150k, it blew again. Fixed it myself for $400, although it was somewhat of a pita engine to work on. Still got 8 Fords!

    I love how Toyota remains the epitome of quality and reliability. Whenever any manufacturer has issues, the response is, "Toyota has issues too!"

    Funny part, I was talking to the parts and service director of the local Honda dealer and he told me that Honda's have the MOST recalls of all car companies. He said Honda has excellent P.R. people and nobody has any idea!!

    I have a 2009 Mazda CX9 with the 3.7 L Ford sourced V6 and I too notice some tapping on cold start up. Is this normal? when the engine warms up it goes away though, could it be the oil? I currently use 5W-20 synthetic. I am used to ticking valves that's normal but tapping is something else.
