Hi there im new to this forum, and have read every post for the last year, and nothing resembles this. (2002 3.3 non supercharged CC frontier  170,000 miles)

I was towing the boat home, stopped at a light and heard someone hitting metal with a hammer about 4-6 times.. thought nothing get to the next light I hear it again. thought it was another vehicle. Backed the boat in the driveway and Heard it again. I looked all over the compartment trying to isolate the noise and i think its coming from the distributor cap or coming from the passenger side of the engine. sounds like a belt slapping or something when listening with the hood up. I am struggling to explain this, I hope someone can help! any advice is greatly appreciated.

Have you checked your oil level?  Sounds like it could be the beginning of a rod bearing failure.  What does it sound like on start up?  Does it only do this when the engine is under load or does it do it at idle under no load.  More info would be helpful!!

One other thing....does it sound like it occurs every engine revolution or every other revolution?  That can help in the diagnosis.
