Customer Question

Hi I have a nissan navara 3l turbo diesel 2004. It has just started out of the blue making a tapping sound which is coming from the bottom end of the motor... was wondering if an oil change would help it?

My name is ***** ***** I am a professional here at Just Answer. I noticed that your question was not getting a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.
In some cases the engine oil can become thin and cause this here and changing out the engine oil and filter will correct this fault but if this does not work I suspect engine bearing damage possibly or a valve lifter/tappet at fault needing replaced.In this case the lifters/tappets will need inspected to locate and repair the cause as well as internal cam and crank bearings.
I have also seen timing tensioner start to fail and cause this as well.
Thanks Pete
