Having the turbo feed from the bottom will increase the oil pressure on the seals, this I would have thought will cause them to fail quickly.
 
Ive never seen a turbo with bottom feed oil pressure, cant see why it wouldnt work, but maybe worth ringing one of the turbo reman people and see if they have any views
Only issue I can see is the oil around the floating bearing cant drain back so could leak past the shaft and into the intake.
 
Wooh not long to first start now!

:D Nope, As soon as gearbox is back it should be ready to fire.

Great work again!

Cheers :)

Yeah, This is kind of what I've read and others saying it's fine.
But then theirs that much contradictory information out their I don't really know what to think.

No me neither, Thinking I may leave it be and keep an eye on it, First sign of oil and flip it back or buy another and put it the right way around.
A HX35 is on the list so wouldn't bother me to much, Provided no other damage happens.

Is it worth the risk of having a runaway with that beast.
 
I have seen a turbo jet being made and tested, this used an untested second hand turbo that showed no sign of oil seals leaking before hand.
The oil feed was plumbed into the bottom and the out was in the top.

Now this did not run be was spun up for a short time in which the seals passed oil.

For this reason I would not leave yours as it is.
 
Done with the engine crane Aaron, will get mine running hopefully tomozz then MOT's thurs/Fri and fingers crossed drop it back at the weekend. Cheers been a life saver!
 
As above, worst case, will be engine runaway if the oil builds up in the turbo and gets sucked through the seals. I have just had this on a VW camper with a passat TD motor with a poor turbo drain.

I wouldn't like to try stalling that in 5th to get the engine to stop!!

Point taken, Will get some heat and try and clock it again.

No worries, No rush either way.
Glad it helped :)

No, I can't see it stalling very easy :eek:
 
Couple more bits and bobs done.

The original plan was to take the compressor feed to the air intake, But now I've flipped the manifold that can't happen. Well it can but would be a fair bit of f*cking around
So I've bought one of these mini air breathers.

Compression fitting on the clutch pipe, As the one on the daf is flexible pipe.
So I'll put one on the daf pipe and join them together.

Next job was to tackle the temp sender.
Originally I was going to use a different gauge and sender in the top hose.
So I bought a blanking plug to go in the original hole.
When it arrived I though I could drill and tap it and put the 200 sender in it.
I did actually look for an adapter and couldn't find one.

Drilled.

Run a tap through it.

And fitted into the block, seems a reasonable solution and keeps the sender in the same place.

Got the PAS prv finished. So fitted the rad, Slam panel and surround.
Hopefully it wont have to come out again.
Had been umm'ing and ar'ing about an intercooler for weeks, Mainly due to money.
But it's easier to do it now than in the future.
So I've ordered one.
Plus I'm back at work next week :( On a plus note it'll give me a couple of quid.

be reet :p just modify the front of the 90 a little and fit a big ARB bullbar to cover it up :D

I'd have to cut half the bonnet of anorl :eek:

Aaron, it's really coming along. It'll be interesting to see a complete to do list at the end of it though...

I'll try and do one when it's all done.
Would have been nice to have one myself :)

Aaron, was there nowhere else where that air cylinder could have gone? Maybe between the rear cross members where the TD5 fuel tank would go??

That's where I think it should go. But this is simple for now and I can make sure it works as it should.

It will go their eventually, But I'll want to build a guard for it. So it can wait for now.
It'll possibly get done before it's on the road, Time and money depending.
 
Aaron, out of interest, where do you order all your parts from, not so much this project but your last one. When I'm looking for bits its mainly paddock and Rimmers. Always looking for other cheaper suppliers. BTW, this engine conversion is something else.
