The sweet smell is really only explained with coolant. Is your reservoir cap leaking perhaps? As far as the fuel smell goes, check your injector rings and any high pressure fuel lines. I know the fuel lines in that generation like to shrink and crack in the cold. Good luck.

Its a 2.5..........

Run it hard...pop the hood and shine some light in the coolant resivoir....

If its like any 2.5s out there, itll be a little foggy in there .)......and should smell nice and sweet ..o and combustiony lol

Mine does......always has.........always will.. ;shrug;. The cylinders wanna rattle around with too much timing......But they run like **** unless you give em lots of timing.........or lots of boost, either way its gonna lift heads, rattle liners and push coolant

Ive learned to accept it as a design characteristic if you will and know that the limits of the 2.5 compared to something like a 2.0............is much less tolerable of timing or boost without major reinforcement and design change (closed deck...1/2in head studs...low comp pistons...serious head work) the list is endless.
...If I had the chance to do it again......
Id swap in a high comp 2.0 , run moderate boost with crazy high timing and high octane and throw my 2.5 off a bridge haha.........well maybe not that bad but hell ive reheadgasketed and upgraded head studs 3 times on my 2.5 and still cant drive it like I want to.
