Yesterday I drove to Manhattan and back for a gig. Basically it was 2 hours down, for the car to sit for 3 or 4 hours, to drive 2 hours back. Anyway, when I got closer to home I was at a toll and noticed a strange loud tap style noise coming from the engine, and it seemed the transmission was having trouble. So I pulled over and parked to check the noise. I opened the oil cap and some smoke came out, leading me to believe some oil was burning up. I'm told this is normal. Especially on long highway trips. Once I got back going again, the transmission acted just fine, and when I got home the noise had stopped.
I'm thinking it was a sticking lifter or valve, but I'm not sure. I've been driving real careful and a lot slower for fear that the engine is going to blow itself out. Today it started up fine and ran like normal with no abnormal noise and nothing different sounding from the engine.
What am I looking at here?
