Thread: New Owner and Q

There should be a water separator on the outside of the chassis, just in front of the attachment of the rear suspension RH lower link.

However, the history of the vehicle could show where the missing separator is. The Isuzu engine was never fitted anywhere except Australia, and even here the turbo version was only fitted to the 6 x 6, although there have been quite a few conversions.

My guess is that the vehicle you have is an aftermarket conversion of a V8, and as there was no separator on the original engine, there is not one on the diesel.

To me the white smoke suggests water getting into the combustion chamber, although it could be unburnt fuel.

There is a strainer in the banjo where the fuel comes into the bottom of the injection pump, but while blockage of this would cause poor performance, it would not explain the white smoke.

Yes, it was a conversion job (1989 with a US spec engine).



I've checked the location specified for the water separator, no luck. Do you think that Racor 215R10 pre-filter/water separator would be a good addition? I'll look into the banjo-bolt strainer. Thanks.

I am not familiar with that water separator, but I doubt it is at all critical as to type, as long as it has adequate capacity with minimal restriction. The original one fitted was CAV.

The attached diagram may be useful, from the owner's handbook.

John, thanks for the fuel system map.

Update: I have plumbed in a Racor pre-filter/water separator and cleaned the strainer at the banjo fitting which had some crud in it. So, there is a new pre-filter, main filter, air filter and a clean strainer.

We are having a bit of coolish weather at the moment(6F/-14C). It starts fine, but is blowing quite a bit of white smoke that has a rather strong fuel smell. Any other ideas?

Sounds like the white smoke is unburnt fuel. There are normally two reasons for this - incorrect injection timing, or dribbling injectors. The manual I have lists static injection timing as 10degrees BTDC for the turbo version.
