Ok i have had nothing but bad luck with this mustang since i bought it (3 months ago). the car sits but i start it atleast 2 days a week and let it run for about ten minutes.. today i drove it about 20 miles the car was running great smooth ride i was enjoying it but once i stopped i smelt something like a burning smell? and i popped the hood and smoke started to come up not too thick but it was white smoke and it came up around the block on both sides. i know the oil needs to be changed but i dont think that would cause it thanks for any ones help!

leaking valve covers....if not that....the seal in the rear of the intake can leak. Feel if theres oil running down the back of the block. The valve covers are properly vented right?

White smoke most of the time means coolant burning off or steam if its grayish, but could be oil too, check for oil or coolant leaks dripping on to a hot surface and creating the smoke.

When the engine is cool look all around the engine, all the coolant Hoses, gasket area's, thermostat housing, valve cover, intake area.

I agree but I know when I had oil leaking from my breathers it created a thin white smoke as well. It may be oil or coolant. is the car leaving puddles??

#1: Find what is leaking
#2: Find where it is leaking
#3: Fix what is leaking where it is leaking

/problem

Most likely the valve covers or the lower intake. My stock intake is leaking coolant. That is fine because the edelbrock is sitting there ready to go on. Just want to get a larger TB first.
