NAVARA D40 Bad valves?

Postby basudai » March 9th, 2016, 5:57 pm

Need some assistance with the YD25 Diesel Engine in the D40 Navara.

I am hearing a tubbing noise coming from the air intake box when opened while the van is idling. I was under the opinion that the injectors needed cleaning as the various signs are present...like black smoking, some lost of power and ruff idle. But I want to know if this is any indication of valve damage?
