i was pulling out of wally world about 2 hrs ago turned on my a/c just cruising as soon as a/c kicked on it started making a weird noise like the a/c compressor messed up or something i looked back and seen a hugh clowd of smoke which i though was r-134.i turned the a/c off pulled over w/the car slill running popped the hood looked and seen smoke coming off the passenger side exhaust manifold .so i turned the car off and looked underneath it and seen a big oil spot.what do you think could of caused that. i started the car up and drove it home it ran good good oil pressure and everything.

 

Check your Dipstick, mine cracked and blew oil all over the Header, looked like I blew a Cylinder.
