Truck pulls last night good run but now have noise!

[generalee31184]

Ran my truck for second time last night in the truck pulls, 275 tune, pulled 312.09ft and ended up 5th of 34 trucks in the class(got beat by fords like mine lol) anyhow now I have a hissing noise coming from engine compartment seems to be in turbo area. Truck still runs and drives the same but have this hissing like noise. Almost sounds like when you pull a vacuum line of a car. Dropped truck off to dealer this morning, see what they say but im just curious if anyone has any ideas? If I play with that arm thats up on the turbo(I am not familiar with what that is, waste gate?) the hissing seems to change a little. I think I blew a line or cracked exhaust or something. This truck is really starting to irritate, I have an engine oil leak they need to pull the engine for, then this past week the brake master cylinder starting leaking, and now this. Im bout to trade this junk in for a new one!!!

Great job and sorry to hear whats goin on

Um... you should'nt be able to move the actuator arm at all if the key is on.

[generalee31184]

Yeah I can not actually move it back and forth with truck on but with truck running if I get up there and try to wiggle it a little back and forth it seems to change to sound of the hissing a little bit.

Sounds like if you can actually get the actuator arm to move slightly and make the vanes move and you are affecting the tone of the hiss then you may have an exhaust leak somewhere.

Got any videos of the pull? Sorry to hear about your truck.

Is the dealer fixing all that stuff under warranty? If so you should be happy about that and not complaining. Not too many guys can take their trucks to the truck pulls and drop it off at the dealer the next day and have whatever damage was caused by it fixed under warranty...

[generalee31184]

Well the results are cracked rh exhaust pipe(flex pipe). So next week the truck goes in to have motor removed for oil leak and replace exhaust. Tranny would have to come out anyway to replace exhaust so am doing everything at once. Damn junk fords!! lol. At least it is under warranty or I wouldnt be pulling at all with it! I love this truck too, but it is the first one I have ever had these kind of stupid issues with. I do have a vid, just have not loaded it yet, will try to later tonight. "If so you should be happy about that and not complaining.

O yeah and engine oil leak and leaky master cylinder are not caused by pulling or tuning... They were caused by whatever piss pour assembly happened at the factory. The oil leak is actually where the two halfs of the engine come together, its weeping out of the gasket there.

Good job. i love to see the 6.4s compete well at the pulls now. Its no longer cummins/dmax azz whooping the powerstrokes.
