Just out of curiosity, why have most people decided to plumb turbo oil return into oil pump cover (requiring tapping etc) rather than into the existing vacuum oil return line which simply requires fitting a 'tee' piece???
Cheers

The vacuum return line isn't big enough to handle both returns. Oil builds up in the turbo and comes out the seals.Quote:

Many more hours spent but not many piccy's..
Fitted a Disco handbrake - still has a slight misalignment on the gearbox end so not sure how quickly the cable will chew out. Will see how it goes for now:

When the 200tdi conversion was done in the past they had run 6mm rubber hose all the way from the tank to the engine for the supply, and adapted the original plastic supply line as the return (8mm OD plastic).
Given that the engine pipes on the Isuzu are 10mm OD, I wasn't convinced that the existing lines were going to be big enough - especially once I'd had to stuff around with adapter fittings that only had about 4mm internal diameter to adapt from 6mm to 10mm.
Ended up biting the bullet and replacing them with 10mm OD nylon truck airbrake hose. Excellent fit on the fuel tank fittings and perfect size to match the Isuzu pipes just using a short length of rubber hose as a joiner.
An added bonus was getting rid of half a dozen hose clamps where the original lines had been adapted, joined and extended.
Insulated the firewall with some engine compartment foam from Whitworths Marine. One sheet was enough to do the whole firewall.
Not cheap, but thought hopefully worth it for the spouse happiness factor.
Its a multi layer foam sheet with dense layer in the middle and foil on outside: https://www.whitworths.com.au/main_i...AbsolutePage=1
Used some ducting insulation tape from Bunnings to tape the joins. Its like a mylar tape with a silver surface.
You need to make sure you rub it down well so the adhesive has full contact. Once you've done that it seems to stay stuck down well even in places where there was a bit of tension on it.
Not sure how it will hold up long term, but has a pretty aggressive adhesive, and looks nice and shiny:p.
Only about $10 for a 50M roll.

Since I've still got plenty of Sikaflex in the tube, I'm wondering if I should clean the sealant out between the windscreen frame and roof, and re-seal it.
Is it worthwhile doing, or is the only way to do properly to remove the roof. If that's the case I'll just leave it for now, as filling it up with Sikaflex will just make it harder to do properly later.
Here's a photo of where I mean:

On the downside, I had my first major stuff-up with the project - while disassembling my turbo to replace the buggered seals.
First turbo I've pulled apart and I forgot about the shaft nut being LH thread.
Surprising how easy it is to shear off the thread on the shaft just using a couple of normal length ring spanners.
So - I now have a nice low K's GT2256V paperweight unless I can find a turbine shaft :(:(:(
Anyone got a spare one lying around :Rolling:

Was that one of those "it wasn't broken but I decided to fix it anyway" moments?Quote:

Almost too embarrassing to post, but hey - experience gained is proportional to machinery destroyed.
Hopefully someone else will gain from my destruction.

OOHHH i realy like that.Quote:

The lever end of the outer cable is threaded so I cut the boss off the original bracket and welded it to the bottom of the tube on the disco lever.
Thats it..

Sounds simple enough i will have a look at doing the same so my left calf dosent become permenently distortedQuote:

I see you've already sussed turbo flanges:)
Yeah - turbo flanges are under control.Quote:

Can get a new turbine shaft out of Scroll in Poland for not TOO many beer tickets - but a bit concerned about a final balance. MTQ cant put it on a VSR as "They aren't rebuildable so Garrett dont make a flange adapter to run them with".
