Author Topic: Custom Oil lines to VNT 17 turbo (Read 3513 times)

I need to plumb my oil feed and drain lines for my VNT setup on my N/A. I have a stock TDI VNT 15 with the center section from jimfoo's VNT17. The oil feed and drain are on the same flange.

I'm wondering why i couldn't just use steel brake line for the feed. I have seen here a flexible rubber hose smeone has mentioned to use for the drain.

I will probably weld a fittting in to my factory pan. Should i use metric brake line or drill out my filter flange and use STD lines and fittings to keep cost down?

I will also be plumbing up th coolant ports too but that should just take 2 straight nipples and some hose routing.

Hi, I've been down this road. It sucks. What I did for the VNT-17 on my 1.5 was used a new factory line from the oil filter flange to the turbo. I purchased one of those tube bending tools from Home Depot, and used it to straighten certain sections, and bend others. The line still wasn't long enough to go down past the TD intake manifold, so I added a piece of Porsche rubber fuel line that I got from the dealer. Fortunately, those little compression fittings like you can get at the hardware store fit the outside of the line perfectly. I cut off the end of the line, added the rubber piece with compression fittings, and put it back together. I also put a little piece of heatshield material around the rubber hose for extra protection. It looks like a factory piece. Now for the return, don't even bother trying to adapt a line to the metric fitting on a factory pan. It's some odd-ball size like 18mm or something. I looked EVERYWHERE, but the only place I know of to get the fitting you need is off of an original return line, which is what I did. I bent it, cut it, welded it, etc. to get it to run from the bottom of the turbo to the oil pan. It really wasn't worth the effort. I would recommend welding a standard fitting to the pan, and just adapting to that. I can post pics if you need them. Good luck.

That sounds like what i thought might happen. If you could post pics that would be great.

Will this fit the stock filter housing? 1.8T is that the VW engine or something else.

That is awesome thank you. That site has some possible stuff to use.

If i had a tee fitting right off the filter flange going to the turbo. Could i put a temp sender in the tee and have enough flow past it to get an accurate reading? The path through the tee would go straight through to the turbo and the temp sender would stick in from the side.

I plan to run a restrictor in line to the turbo. I'm concerned that the oil temp would then be in accurate.

ATPturbo.com has many fittings for VWs so i think i can make their 8V kit work for the VNT.
