Thread: Isuzu Engine Swops for Dummies

For some reason the fuel shut off is sprung in reverse. And a leaky injector. Fixing it now.. see how it goes

For some reason, as I only found out today, I seem to have an injector pump that is spring loaded to stop, not run

Have compared it to a couple of other injector pumps, including Damien's, and the spring on mine is a mirror image of all of the others. It's not just a case of simply flipping it upside down either, or something that's been chopped and changed, it's been manufactured like this. It's obviously not a big fix, just bizarre. Any ideas if some of the 4BD1 driven vehicles were set up in this way???

the original engine may be from an industrial application where the equipement is required to shutdown in the event of an emergancy or loss of control power.

Its too quiet on this thread - either Mike is catching up on sleep now its all done or is out doing laps of Gippsland with the Isuzu smile

Whats it like to drive with the VNT and huge intercooler? Have you found a place to store the fuel screw yet

Does "losing the screw" kill fuel economy much?

unless he's pushing it, he isn't doin laps anywhere

Although I require my shed back this weekend to prepare for a family holiday, so he better get a move on

It is running, just sorting the Turbo out, this would have to be one of the smoothest 4bd1's I heard.

Mike is trying to stop oil coming out through the turbo at a rate of knots - have had to rebuild it twice so far. Finally looks to be sorted, I think - road there's a film of oil seeping past the turbine that I'm hoping is just residue from earlier. Engine does sound smooth though, if I do say so myself. Long overdue an update I know, but have been busy...

mike, how have you done the return line from the turbo oil feed? it needs to be on its own back to the sump not tee'd in to the alternator return.
