Ok i just had my friend go out with me to my truck to see if he smelled it also and he did. When i start the truck he puts out a sweet smell kinda myabe like antifreeze. If not antifreeze what could it be and if it is what is going on. thanks

 

Hold your hand about 2 inches from the tailpipe when you start it, then look at your hand to see what it's blowing out.

 

looks like water but has a sweet smell

 

wow...thats a real pickle

 

Head gasket or intake manifold gasket is probably leaking antifreeze in your motor.

Man it better not cause the Ford place just put that motor in. And it was a used motor. i will be really pissed. Is there anyway i could check to make sure it is that ?

 

Crap sorry i forgot to add i just went to get some lunch and it sounds i have a valve hitting something and it gets worse when the speeds increase

 

An '08 and ford just put a USED motor in it? What's the deal there? If you're smelling "sweet", you've got a coolant leak SOMEWHERE. It doesn't take much of a leak to smell sweet, sometimes they're hard to find even, they can be so small. I don't like the sound of what you're saying. I hope for your sake that that engine isn't a trash can case. If you smell the "sweet" in the wet exhaust, it's getting in the combustion system somehow.

 

Probably not worth the effort, sounds like you've got bigger problems there, but the way to tell if you have coolant leak into the cylinders is take the plugs out 1 by 1 when it is WARM YET (as in just shut off) and hold a make-up mirror or mechanics inspection mirror right over the plug hole. It will fog up immediately on the cylinder(s) that have the leak. If they put an '08 motor in that '08 (as they should), it will have the new 1 piece plugs and new style heads so you won't have to worry about breaking the plugs off when you take them out quickly to check for coolant.

 

Sorry its my 06 F150 not the black 08 in Sig.... I have 2 F150's the black one is my wifes.. the 06 is mine and they put a used 06 motor with half the miles in about 2 weeks ago.

 

Any kind of warranty? I'd get it back there ASAP.

 

well i got a 90 day or 6k mile warranty on it and i have maybe drove it 200 miles in the 2 weeks, so i am good there

 

well, take it back then
