My car is making same noise as TOKEN'S.
Just checked flex plate and it is fine. put stethescope to oil pan and that seems to be only place on engine I hear any awkward noise directly. Noise is just transfering to front right side.
Now noticing Oil spraying out of exhaust.
Fine mist with no smoke.
Oil pressure stays consistant at 65.
Other than noise and oil spray car runs fine with no loss of power.

Would a rod bearing cause this. or could it be a crack in block at exhast mainifold?????????

 

that happened to me and shortly after my motor went
when oil is coming from the tail pipe your burning oil atleast thats was the deal with my car and I had some bad rings which is why I was burning oil but I could be wrong

 

are you sure it's oil and not carbon build up? But like Kairles said... it's probably your rings. A compression test would better determine that.

edit: a rod bearing would not get oil in the combustion chamber. If your knock sensor works still though, and it was a rod bearing then you'd notice the lack of power... since it would retard the timing a whole lot.... ask me how I know lol.

Also, have you checked your plugs? The oil has to be getting into the combustion chamber after the spark has fired, otherwise you would have blue smoke, but there would still be quite a bit of oil on the spark plug.
