Hi All,
We have recently increased the WVO component of the duel to 80%WVO/20%ULP on my son's Navara. The starting was initially harder but cycling the glow plugs 2 or 3 times prior to starting has fixed that.
There is some noise (light knocking) from the engine for the first few minutes though and although I haven't had a chance to look closely, I assume it would be the IP. This wasn't evident at 50WVO/50Dino. If this is so I'd further assume cavitation of the IP until it warms sufficiently to adequately thin the fuel.
Wouldn't this being doing the IP damage? The noise may well be valves etc too. Would reducing the WVO component of the fuel until there is no knocking be an fair indicator of the appropriate mix at the same ambient temperature?
