New problem

SoCalSHO · November 29, 2013, 04:36:18 PM

So, I had new plugs installed, oil change, trans fluid changed at my dealership (Got a nice Mercedes C250 as a rental). Picked up my car Saturday, Drove it home, strong oil smell. No smoke that I can see, but when I slow down or come to a stop, strong oil smell. Got home, loaded tune. Driving it around later that night, I get on it, just before it shifts, a loud squeal. First thought, wow, the plugs must have worked, now I can hear BOV (or the Ford equivalent). Drive it around the next day, when I hit the go pedal to pass, more loud squeals, under load, but not close to shifting. Happens with A/C on or off.

I am hoping the dummy that changed the oil, somehow spilled some oil while doing the change, and it got onto the belt/pulleys, thus causing the strong oil smell and squeal noise. Checking the oil level, it is good. From what I can see from the top of the belt, it looks fine without putting it on ramps and looking underneath.

It sucks when I cant have a little spirited driving on the freeway.

Anyone have any other ideas? Tough to diagnose over the net, but it is either a tensioner, A/C, Water pump or alternator. Glad I have ext Warr.

Your diagnosis of oil on the belt sounds pretty good. Hopefully that is all there is to it. I would think it wouldn't take too long to go away. You might not get smoke if it just spilled on warm parts as opposed to hot parts, ie: pipes,exhaust mani, turbos. Sounds like they had the "kid" work on it.

Thanks Dave, That Is What I Am Hoping For Also. Will Put It Up On Ramps Tomorrow.

Hopefully you guys have it figured out.... Here's a quick check you might do.... let the pulley contact surface of the belt run on a bar of soap while the motor is running for 10-15 sec. If that temporarily stops the squealing under load it solves half of the problem... diagnosis, belt slipping. And the soap comes off with water.

Thanks for the idea. I may try it out in the morning.

Can anyone post a link for the turbo leak TSB? I think there was one, but search does not work.

So, I found the source of the burning oil smell, the front turbo is leaking onto the front cat. I specifically asked them to check this last week. Oh well.

I'll dig around for it. But IIRC, the last one I saw posted was for the 2010/11 model years.

It involved replacing the gaskets on either (or both) the oil return line, and/or the oil supply line.

Sorry to hear that Robert. I was hoping for just a little spilled oil.

No problem, don't have to look for it. I just did not remember if they replace the lines on one or both turbos, or even just replace the turbos (that would be nice).

Glad I am off work for the next 30 days.

Hopefully they get your fixed up in a jiffy.

BiGMaC · November 30, 2013, 05:55:14 PM

Glad you found it... nobody cares as much about your stuff as you! Hopefully an inexpensive fix.

TSB# AS-21759. I do not have the fulltext of this advisory.

DJE624 · November 30, 2013, 06:15:00 PM

Since there is a TSB on this, I'm wondering if these guys with the bad smell have the same problem. They say it happens after getting on it (when Oil Pressure jumps). Just a thought.

BiGMaC · November 30, 2013, 06:17:59 PM

Here is a link to the Ford Service website.... They will sell you the TSB.

The NHTSA issue the same thing, couldn't find a recall for it. but it is the front turbo seal leaking oil.

Since i am also one of those from way back, I looked under the car many times in the past to try to diagnose that. Never had a leak like this one. It was readily visible. Actual drops of oil onto the cat, and onto the tray under the engine. How these "mechanics" never see them when doing an oil change when I specifically ask them to look is beyond me. Oh well. I should look into the tube to see if I have a lot of oil, knowing they won't check. BTW, all of the leaks on my car have been found by me, not Ford. They should be paying me.
