Now I just need to sort my Turbo feed, thinking of double banjo fitting at the vac pump.

As for the oil pump cover, I think I wasn't supposed to notice that had been done to it, because I definitely knew I'd seen one that was centre tapped, I also noticed one of the bolts had been snapped off on my good engine:mad:
Never helping anyone again;)

I see.. :(

Hi guys after reading through all the above, is there a concensus for where the best/easiest place to run oil drain hose? Took off the cover below the the oil breather hose is, and doesnt look like the right spot, am i meant to just aim for the middle of the plate and into that circular thingy?

Sorry not sure why but tapatalk doubles up on photos

It depends how big you want the drain. From flagg's photo the biggest you could manage without interfering is a 1/4". The centre of the cover holds the shaft in place that you can see looking into the block.

My cap looks different it's completely flat see the pics.

When tapping this do I want the barb to sit in centre of the cylinder or just outside it? And should I going the barb flat so it doesn't come into contact with the cylinder

So it is. What year is your engine? That's definitely different to most of the County Isuzu's.

Judging by the photo, it looks like the oil needs to go slightly down the side? Wherever you think it will get to the sump the easiest! The angle of the barb is just the best you can so you can connect a relatively straight hose to the turbo drain.

Engine is an 88/89, but it's a perentie so it may have had a heart transplant somewhere along the way. Judo I've got a turbo just like yours think the oilike drain is quite large and there's not much room down the side of that cylinder could probably get a large barb and cut it flush with the plate but probably get only a few turns into it

The Perentie engine has a diamond shaped plate held by two bolts, just in front of the starter motor. That's where turbo motors drain to.

Awesome thanks rar110, this will do nicely, large diameter hole into engine

^ do that!
