If your exhaust is a kind of sweet smelling sounds to me like antifreese is getting into one of the cylinders wich explains the hard starting the exaust should have slight sulfur smell to it you could pull the plugs out and look at them to see if antifreese is indeed getting into the cylinders

2004 Jeep Liberty it pasing oil an prestone that just apend onse

is it leaking, or burning in the combustion chamber? Comming out the tail pipe? Blue smoke is oil, white smoke is water, black smoke is carbon. Smell your exaust; smell like "prestone"? Does the engine over heat? My guess would be a bad head gasket. Is the oil a light brown color?

Burning rubber smell from Subaru Legacy

Please have your exaust pipes checked, perhaps a mount is burning. The catalytic converter can make a nasty odor when it is clogged. Check the wear on the serpintine belt.

Had a growling like noise when excellerated and now it is a grind

Note the smell of your exhaust. If it smells like sulpher feel how much pressure is coming out the tail pipe. If it stinks and there is little to no pressure, the cat converter is plugged up. Good Luck- Ned

the 3.4liter engine has a bad habit of going through headgaskets you may want to do a compression check on it and see if you have a bad gasket. most of them that i see with this have about 120k on them when they go bad

My 1999 jeep C started leaking fluid somthing broke underneath

Check all fluid levels, especially oil and transmission. You are probably bone dry. After topping off fluids, check to see what and where it is leaking from.
