Custom TD5 Turbo Oil Drain Hose...

[Hamish71]

I have a TD5 running VNT, with a provent.

I followed advice from here when installing the provent, and have brazed a connector onto the turbo drain hose for the Provent to run off to. I joined it quite high, so as to avoid the heat damaging the rubber in the sheathed hose. As such, after leaving the provent, the hose runs quite flat to the drain hose. Flat enough that the one way check valve doesnt appear to be opening and thus it is not draining. I am thus getting oil build up in the bottom of the provent.

2 Possible solutions. Raise the Provent. Lower the drain. I cant raise it anymore. Thus I need to lower the drain hose join.

I am seriously thinking about building a custom hose. Why? Its not to save money....never is with cars! but more for the fun, and to arrive at a technically superior solution.

In principle, I want to take a turbo oil drain flange....

(Oh, buy the way, Im not right into turbos, so if someone could tell me what turbo oil drain flange would FIT a TD5, (eg. GT40 T03...whatever) Id appreciate it.)


.....connect it with some suitable braided hose, and then run id down to a t piece/y connector something like this:

.... just short of where it screws into the block.

I thought an added benefit would be that I might be able to shape it so it doesnt interfere with the bloody oil filter?

Am I crazy, or should I just go find a drain pipe at a wreckers and weld the connector lower?

Not crazy in the slightest..

I've been thinking the same thing (havent dropped the provent in yet).

If you run with it, consider this and order for a 2nd unit/assembly :cool:

....or maybe we are both crazy.....havnt considered that option yet!:bangin:

Alright, failing someone being able to tell me what flange to get, I will either rip mine out, or go find a wreckers one, and start to do the rounds on the weekend. Do you want bling, or not bling?:)

After destroying my drain pipe trying to get it right I bought a catch can and a new drain pipe.

[LOVEMYRANGIE]

I was contemplating either one of the adaptors and modding to the top of the sump but it's probably easier again to get a solder T piece and properly cut it into the line rather than braze a normal fitting.
Going to get another line "just in case" as Murphy strikes at the most inoportune times....

How about we go the Bling :D

[Hamish71]

OK, I went and bought a drain pipe from the wreckers....

There are multiple options for getting a fitting for the Provent drain into the pipe, but im actually more interested in the routing right now, as this will determine both the pipe make up, and perhaps the ability to get it out of the way of the oil filter.

In a word description, the drain drops straight as solid pipe, then makes a turn both towards the engine/towards the vehicle centreline. (ie. it turns direct towards the point where it screws into the block, passing under the oil filter). Then there is a short section of braided hose, before another solid piece screwed into block.

Any suggestions, considerations or thoughts on a more suitable route?


To start:

Must "slope" downwards to maintain draining capability
Must not get too close to the turbo down pipe
Must arrive at the engine block on a suitable angle to allow a t or y piece for the provent line
Is it possible to set this up as a quick disconnect, either just for the provent, or for both? Possibly a t or y screwed into the block with 2 qd's? At the very least, when changing the oil filter, qd the oil drain and pull it out of the way? Could you get to the qd with the dump pipe still in place?
A simple solution might be to shorten both solid pieces, and merely add more braided hose?

hmmmmm......I like bling but......

I went and sat down with the guys at Meridian Motorsport today, agents for Speedflow, and "designed" on paper this pipe. Lazy $140 in pieces, plus $120 in labour if they do the fabrication....
The finished product would be a work of art, and I might have gone for it at half the price.

Might see if I can do the design using other than speedflow parts and see if I can get the price down.

How about this:

XAVIAR Turbo Oil Drain Pipe Teflon Garrett GT15 17 20 (eBay item 320606583935 end time 19-Feb-11 05:16:08 AEDST) : Cars, Bikes, Boats (http://cgi.ebay.com.au/XAVIAR-Turbo-Oil-Drain-Pipe-Teflon-Garrett-GT15-17-20-/320606583935?pt=AU_Car_Parts_Accessories&hash=item4aa5a43c7f)

Then use a t or y piece at the bottom to splice in the provent line.

Parts:
- $60 for this kit
- $10-15 for the t

Fab: Welding the original fitting from the oil drain pipe that screws into the block onto a t piece.

Benefits:

Neater.
Provent drains down.
To remove oil filter, either push hose which will be much more flexible out of the way, or, unscrew it at the flange.

My provent has a long hose with a plug in the end out the passenger wheel arch where I can drain it periodically. not enough oil to worry about recycling it into motor.

i ended up with a spare pipe oil drain pipe if anyone needs it. open to offers

still haven't finished the other, but damn thats a nice drop :)

but yeah a spare bottle of OP wouldn't go astray round here :)

Sold then!!
Give me a week or so as I'm a bit cash strapped with some recent purchases.

Any news?

How about seeing how much for 2!!!

I've got some flanges here from the turbo...

Anyone know the block ends thread size/details???

[Hamish71]

Sorry Mike, been spending a lot of time up in Canberra of late, and not getting much time to play with Land Rovers.

Im still thinking the ebay Xavier kit is probably the best start point, and good value. Ideally, there would be a proflow/speedflow connector that is the same as the thread size, angle as the block end of the stock turbo pipe. Then this all gets really simple. The xavier kit, t or y piece at the block end, screw it together.

I just havnt had time to chase it all down.
