Strange Turbo Problem ..

[jester7100]

MMMK So I purchased a 2010 SHO two weeks ago sight unseen after being told everything works great and it has new Headgasket / timing / water pump ect...

Come to find out driving it 3 hours home I didnt have near the power i expected. No turbos going it seems. They vented the bov's to atmosphere and i get nothing from them. Fast foreward 2 weeks after having 2 people look at it and cant figure out whats wrong aside from some oil in the front turbo I ordered two new ones
and figured screw it just replace it all and on the road today .. Everything started working for no reason at all for exactly 5 damn min and then quit again. Replaced the solenoid already and at this point I'm not sure even what to check.. told my mechanic that I got 5 min of randomly working turbos and blow off noises and then
it quit and his answer was.. HUH..

Any thoughts on next actions before I just drop it off at the dealer?

You have codes? IS there enough consistent electrical voltage to run all the processors correctly? This car is highly susceptible to malfunction under low electrical delivery and eats batteries quicker than alot of vehicles. This could be anything without more info. Spark, timing, processor, fuel... too much with little to go on over the interwebs

 

[jester7100]

No codes of any kind

Ide have to go with dealer, when i had misfire issues, even with logging for tuner, and logging with forscan, neither of us could see what was going on. The window to catch it was to small. Dealer diagnostic saw the fuel trim go haywire, all in a quarter of a second. Surprised how fast these cars react to save themselves. No codes for fuel injector, but symptoms lead to it. I paid $138 for diagnostic, declined work and fixed it myself.

Being a 2010, glad your replacing both. Before you go to dealer, rule some things out, like new plugs, coils, O2s, battery, check alternator. And depending on mileage, new injectors. Oil in turbo is a scary thing, they can empty the oil out of a engine really quick.

I love this answer.

You can save days and weeks worth of brainstorming and eliminating when paying a pro with the correct equipment for a good diagnostic can get the info much quicker. This is all depending on equipment and a good tech but, so often, really worth the cost. You can always take that information and go attempt to fix the issue yourself.

Got a great tech too, even threw in a boost leak check. Told em I just put new plugs and 02s on less than 500 miles before, he said change em, change everything to new again. And run the **** out of it, get all the buildup out of system.

Well..it spent the day at ford. The 2 techs and the ex engineer say it's perfect and has no issues or engine lights and is making the boost it should. Previous owner vented bovs to atmosphere and they currently do nothing... no sounds at all. I can take the intake apart run the car and zero turbo sounds at all and the car has no wow factor driving it. Am I just getting screwed here?

 

[luigisho]

Looks like it from way over here. But I can't drive the car so just internet noise

Check the BOV's for torn diaphragms. No whooosh and no power suggests bad BOVs.

They were lazy, no code, no looking. Find a tech that's been around. **** even with my misfires it took a few misfires before codes would even pop up. If there saying you got boost but your not hearing BOV valves, they missed the boat. Those both vented are loud and can be annoying as ****. And not hearing them at all, that's just not right. And Texas Marauder is correct look at the diaphragms. Mine was torn on my F150. They are a wear item.

Do you have any torn couplers? I would check to see if the charge pipe from the intercooler to the throttle body has come loose at the base. Perhaps a cracked charge pipe, from the turbos to the intercooler? What about the noisemaker? They are known to leak under boost.

 

[jester7100]

Hooked up a computer drove around and highest boost gets is -.45

You have a massive boost leak. I would starting checking from the turbos to the throttle body. You might even have a hole in your intercooler.

The problem is twice now it has worked perfectly for 5 minutes and then immediately quit again

Victory! New front turbo for the win

 

[jester7100]

Old one was chewed the **** up. 3 mechanics and all I had to do was take it off to see the problem...

 

[SeanDev]

Running stock charge pipes? If so I recommend ECO power parts charge pipes. And they should have done a smoke test boost leak., Again back to what I said earlier, lazy techs. Glad your getting her fixed.

That sucks. Great techs are worth it. Lazy and average or below (and cost containment) are why alot of us do our own work. nobody cares as much about your stuff as you do. Glad you got it back to normal.
