Default Identifying oil line

99 Miata. The car had a VF supercharger installed at one point. Maybe 3 years ago or so. Guy before P.O., installed it, then it supposedly broke, the engine went kaput & he ended up replacing the engine without the charger. The details are still pretty shady. Well, there's some type of oil line still just hanging there. Would it be some type of oil feed? I'm in the process of turbo build & didn't know if I could use it as a supply or not. Hopefully you can see what I'm looking at here.

Based on that second photo, this is indeed an oil feed line. Normally, that hole in the block is just for the oil pressure switch. It now has a T fitting installed in it, with the pressure switch in the side and the oil supply hose on the end.

It wouldn't be a bad idea to consider replacing that rubber hose with something more significant, but that is an idea location to draw the oil supply for a turbo from.

^Awesome! Well my supply line is sorted out now. What do you recommend to replace that hose with? Braided line?

-4 an stainless line to feed your turbo. Preferably wrapped in fire sleeve so it does not rub through things in your engine bay. Open up your phone book and look for hydraulic shops. They should be able to make you a line

One other question. Does the VF Supercharger for these require an oil drain?

No clue, I would look for the VF Supercharger directions and see what they say.

Yep. It's so dumb.
Probably one of the reasons they are no longer for sale.

Holy **** I've struck gold. Reason I asked is because that's the charger that was installed several years back on this car. My Dad pointed out an out-of-place hose a couple weeks back. Didn't think much of it. Welp, sure enough, I already have an oil return! Easiest oil return install ever.


You can see the top held in with the clamp. And yes, I will be replacing that hose as well.

You haven't struck liquid gold, that's just an epic oil leak.

Dammit I was about to say that.

Buy some cans of brake clean, and spray the **** out of all oil unions, disassemble, reassemble with quality parts, then get those areas super clean with brake clean again. Give it a week, and if it's still clean, carry on.
