Ticking
 

Well my latest problem is I can hear ticking coming from the right rear of my engine, around my exhaust manifold and 02 sensor, i'm assuming i'm hearing an exhaust leak, probably from the manifold, what do you guys think? thanks

I'll check it out closer tomorrow morning, see if some manifold studs have broke ect

I would suspect a vacuum leak, but do not rule out a broken flex plate. If you have a mechanic's stethoscope, you can pin point the location of the problem.

I had a similar noise and it turned out to be a loose spark plug #5. I tightened it up and the ticking noise went away. I have no clue how it got loose but it did.

I sure hope it's not my flex plate, and i'll definatly check my spark plugs tomorrow too.
