Light rattle from engine

My engine is together and running finally. It sounds strong but there is a light rattle from the front. We have tried adjusting the timing chain tensioner-chain is new-but the noise is still there. Do the tensioners ever cause problems? I didn't replace any parts of the tensioner since it looked ok.

David, Have a read of this. May not be but worked for me. It is easy to distort the tension quadrant device when replacing the sprocket. mine was twisted. Quite hard to see.

Today I stripped out the whole tensioner assembly and checked it-I did not find any problems. It is straight, there is no play in the tensioner sprocket and the 'washer' was on the end of the adjuster. I put it back together and could only run it briefly due to the location and could not test drive but it sounded better! I will run/drive it tomorrow hopefully and will report back.

I had a similar noise and it turned out to the the fan blade rattling in the rivets.
Once I changed to an electric fan and removed the old fan it stopped.

Steve: I don't have the original fan-I have an electric fan now so that was not the cause of the noise. I ran the car today and got it quite hot - the noise is very minor now-in my humble opinion-I think I will run it for a while and see if it changes.

My fan motor bearing was making a ticking noise until I upgraded but it sounds like yours is new...
A leaky exhaust manifold gasket can make a ticking noise too.

Run the engine for a VERY short time with the fan belt disconnected and see if that stops the noise. That will isolate alternator, fan and water pump as sources of the noise.

Thanks for all the input everyone. I tried and eliminated all the points that were raised.
Personally I think it is OK. There is a light clatter from the engine which as Bill said is the cam lobes hitting the buckets. There is also a slight chain noise but nothing serious after further adjustment.
