providing oil to a turbo

[wdkingery]

I have the vnt, and I swore prothe had a td oil filter flange... But I cannot find it anywhere on his myriad of sites. Isn't there a spot on the head I can work from? Any other ideas?

not enough volume from the head port..

modify a n/a filter flange!

Couldn't you just use the n/a filter stand and use a "t" fitting for the pressure sensor? I'm assuming the n/a stand has an access hole directly above the filter?

usually there is a secondary, plugged port on it also..

I drilled and tapped my N/A flange to 1/4" NPT.

yes i reckon it might go this way. i'll attempt to figure it out.
thanks for the mount lucas!

The AHU TDI engine used the head for supplying oil to the turbo.  The oil line threads into the same port that the oil pressure sensor uses.  I bet it would work fine on the 1.6 also.

AHU had a WAY DIFFERENT oiling system than the 1.6. chain driven high volume oil pump.

im going to stand by what i said.. i dont think the old 1.6 will supply enough volume to the head port..

I don't think I would trust a head supply either, but I was thinking the AHU was the same as the AAZ block wise? I know the ALH has the chain pump, but did the AHU?

Like I said, I never saw much oil to the cam in the head, so it woud scare me to run it there. Also, IIRC the head is last to see the oil, so running it off the flange should be cleaner oil if nothing else.

ROR, you're thinking of the ALH.  AHU was an AAZ block with a crank sensor added.  

5/16" OD steel tubing (brake line) works as oil supply line with the stock VNT turbo oil supply fitting/nut and part# 52215K507 from McMaster.  Drilling the filter flange to NPT and using an NPT to 5/16" compression fitting and a tubing bender would get it done.  Done forget to add at least one anti-vibration clamp to the line.  Also easy to make using sheet metal and a short piece of 5/16 ID hose.

Nicely said Libby.  Anything I build now I use #4 Stainless steel braided line.  My compound build uses one feed off the oil filter stand and the other turbo is fed from the back of the head.  I primed the engine before I fired it up and I got tons of oil flow from both lines.

sorry.. my bad!

that kinda embarrasses me a little bit..

so this means i can use the head or no?
i'm not sure about the drill tap.
also, does the brake line bolt directly to the VNT?

[fatmobile]

 Yes, I used 5/16" brake line for my VNT 15.
 Drilled 1/8" NPT and got a compression fitting from Napa.
 The stock fitting on the VNT will accept 5/16" brake line in it's compression fitting.

... so this means i can use the head or no?...

Especially if you're using a stock pump on a factory '85 Golf/Jetta 1.6, I'd agree with theman53, inasmuch as the cam and valvetrain need all the oil pressure & volume that finds its way up there to the head. Sometimes even that's not enough.

The filter flange is a much better source from which to lube the turbo on a 1.5 or 1.6. Going to a higher volume pump might be of benefit also.

I forgot to mention;
 the Rabbit oil filter flanges don't work with the oil cooler sandwich plate.

 The seal surface isn't wide enough.
 If you are going to drill/tap a filter flange, use a later one with the wider seal surface so you can put an air-to-oil cooler on it.
