Default NA-T oil feed

i saw this on a skyline thread. the fuel pump for the 2jz has the same bung fitting that threads a 3/8 fitting, it is the part end that says TOYOTA . can it be used with a reducer for the turbo feed line instead of off the oil filter spot?

Not sure, never really seen that method. I like using the is300 union bolt. It works great

I have been using an is300 union bolt for years now, wouldn't do it any other way or mess with the oil pump at all.

If you go buy an is300 one or one from a vvti n/a supra (toyota is less expensive), it is already drilled and tapped for a fitting. This is not exactly the same thread as the aftermarket stuff, but it will screw in enough and work, I used some liquid sealer on the threads and it has never leaked on me.
you can also retap it and use it if its not threading properly for you, or take your original one and drill it and tap it.

So people can do this, instead of drilling into the oil pan?

You don't drill into the oil pan for an oil feed line...

The is300 union bolt is the cheapest and easiest way to accomplish it. It comes predrilled, I tapped it for the line im using. Its foolproof.

indeed, there is a washer also I think. its a bit tricky to get the old one out and the new one in as it holds the oil filter housing but nothing a few minutes of fiddling wont solve. easiest oil feed line besides teeing off the oil pressure sensor, which is what I do on other toyota motors, but you usually need a special bspt Tee fitting, alot of the toyota sensors use a british standard pipe thread fitting, in fact I think thats what the is300 bolt is originally tapped for.

I'll give you guys a hint on my preferred way to route the oil feed line on an na-t using the is300 union bolt location.
Keeps it out of the way and hidden for the most part except where it pops out next to the distributor.

you need a 48" long line with a 90 degree end at least on one side (I use a -3an line for my journal bearing no restrictor).
you put the 90 degree end on the union bolt, and point the line going straight down towards the ground.
you then cross the line right under the front of the oil pan above the crossmember (protects it) to the passenger side.
Then you snake it up right next to where the water pipe is basically right behind the distributor.
Zip tie it to make sure it won't ever get near runner #1.
Then you are basically right next to the turbo, you can run the straight end into a 90 degree fitting on the turbo (or get a line with 2 90's if you have a straight fitting on top of your turbo).

Does this really work? Have you been running the line like this on your setup? Because I'm looking for a nice way to run my oil feed line. I thought of putting the feed line through where the harness goes through valve cover, bad idea?

Sounds good, ill just go that route. Is the sheathe for keeping heat in and protecting wires or the opposite? And where can I get one?
