It sounds like my engine did before I had it fully rebuilt.   Rod knock.

Yes, I would say noisy crankshaft, same diagnosis though, probably needs a rebuild

Crankshaft Engine Noise

Post by Mark P Hatten »

Just as a side note. Not trying to upsell this poor guy.
I'm planning to list a VERY-VERY nice used Honda 600 N or Z Crankshaft on E-Bay soon. I'd rather sell to a member or enthusiast . $350. plus shipping. I will post the link here when I do.

When I listen to the audio,  I am hearing a rattle which seems to have a frequency which is drifting around your engine rpm.  That seems odd if the problem is in the crank,  connecting rod, or valvetrain area.
Here are the things I would check before deciding if I needed to disassemble the engine;
1. heat exchanger;   when you are standing in front of the car and looking down on the engine,  you will see the heat exchanger on the right side.  The pipes from the exhaust manifold connect to it.
Remove the rubber tube  which goes between the heat exchanger and the blower next to it.  Looking into the heat exchanger,  you will see a bunch of fins.  Those fins should should not move and there should be no loose metal  inside this chamber.  If the fins loosen from the pipe,  they will make a sound similar to what I am hearing on your audiio.
2. rocker arms: remove the valve cover from the top of the engine and inspect all the rocker arms.   When the engine is warmed up, you should feel almost no free play between the rocker arm and the camshaft or the valve.  Look at the condition of the camshaft lobes.  They should look bring and shiny with no craters or rough spots.
3.  fan housing:  the fan housing should be attached tight against the engine.   If you feel any movement, it can cause a rattle.  You could also disconnect the fan belt from the main pulley and start the motor.  If the problem disappears  when you start the engine,  then you have located the area of the problem.
4.  crankshaft:   if the crank has a problem,  the repair is going to be costly.  You can use an engine stethoscope (available at auto parts stores and Harbor Freight .....mine cost lest than $10) or a long metal rod to listen to your engine.  When you go though the engine cooling fins and listen to each cylinder barrel you can determine in which area of the engine the problem occurs.   You could also do an engine oil analysis and a high iron content indicates a major problem which will require a crank replacement.   You could also look at your oil filter and if you see any metal particles,  the problem is very serious.
Good luck and hoping the problem is not with the crankshaft,
Dale

Firstly thank you very much for your email and sorry for my English. I only speak Spanish.
1., This model has no heat exchanger. That is not the problem.
2 fan cooler has all new rollers and is secure. Nor is this the problem.
I will check the state of the rockers.
I hope the crank is good because in Spain there is zero parts.
Thank you very much again.

Toni;
    Dale is corrrect on the Mechanics Stethoscope, it's been a part of my tool box for many years.  But you have to use it correctly, hold it by the metal rod and not the plastic collector at the top of the metal rod.  And if one is not available, a long screw driver held to the ear and touching the area you want to check will also give some indication of where the sound is coming from.  The key is to remove doubt - Go to the video https://www.youtube.com/watch?v=9JDhEwMS_Us

before I had my Mechanics Stethoscope I use a dowel pin and it worked well but the stethoscope works so much better.  if the noise is coming from the out side you can put a piece of copper tubing instead of the stethoscope and use it to find outside of the motor noises.

I hope to find the source of the noise. Problem here is to find parts. Be no cars here. I have the only one in Spain.
