My name is Austin and I'm 19 years old. I recently bought an 86 mustang gt with a 91 mustang gt engine in it, 5.0 HO motor. Bought it in Kentucky and drove it back fine. After driving the car for a bit and looking around, Ive kinda found the few things the guy had Jerry Rigged. For example, a COMPLETELY covered water pump in JB Weld, my gas tank fell because of poor support from THICK GAUGE SPEAKERWIRE holding it up, and lastly some lazy wiring. But anyways, about a week ago I noticed that oil was starting to pool up on the crevices and little valleys on top of my motor. Leaking from behind my intake and covering the back end of the motor onto my transmission and exhaust. It doesn't leak a whole lot, it has just started to gather the more I drive it. Therefore causing it to smoke when motor is hot. I bought intake gaskets and valve cover gaskets, because that what I THINK it is. I'm new to the 5.0s and know nothing of their common problems, so I would love to hear any advice or tips on what could be wrong and what I could do to learn and make this right. ALSO, sometimes my car idles high at random times. Between 1100 to 2000 rpms. Not sure if its a serious problem or what. Like I said, I'm new to these cars, as I was always a Mopar guy. If anyone could help me out, it would be greatly appreciated! Please and thank you!
