My N600 engine sounds like a bag of old nails. I have replaced the
oil pump and primary driven sprocket (because the eccentric on the
primary driven spocket was worn), checked the primary drive tensioner
(works fine), checked the crankshaft main and big end bearings (no
free play at all), checked the cam rocker clearences (100% correct),
and run the engine briefly with the fan belt removed to eliminate the
cooling system as a noise source (made no difference). Recently I
checked the cam chain tensioner and I don't think it's working
properly. Could chain lash cause the noise I'm hearing? And if so,
does anyone know where I can get hold of a new hydraulic tensioner?
Mechanical noise
Re: Mechanical noise
put a long screw driver handle to your ear and touch it to various parts of the engine while it's running. This should let you know where the noise is coming from. Then rev it up a bit and see if it is the same or goes up or down with the rpm's of the engine. Kind of lets you know if the noise is part of what is turning or not. If it really is a rattle could be in the heat exchanger and the screw driver to the ear trick should point it out.
If the noise is where the engine numbers are, then the oil pump piston is hitting bottom. If it's on top then you may have a stuck valve...... Get the picture.
Look, smell and listen to your engine and you should be able to find out what is up.
