Has or does anyone hear a slight ticking sound in their Yanmar diesel engine.
Almost like a valve lifter noise.
I always wear hearing protection when running the tractor.
Recently I have been walking beside the tractor as my daughter wants to help out and run the tractor all the time.
I haven't been wearing the headphones and I can hears what sounds like lifter ticking.
It is not real loud but I asked my daughter and she can hear it too.
Tought back to when I have washed the tractor when idling without hearing protection and never remembered hearing it then.
The sound increases and decreases with the RPM's.
The sound even disappeared last weekend when the engine was hot but returned the next day.
The dealer was called about 10 - 12 days ago & a mechanic is going to listen to it tomorrow afternoon at the house.
The motor has about 37 hours on it and I already changed the oil at 34 hours.
Starts great, full power, idles smooth.
Any thoughts?
Injector, valve train ??
