I'm working on my first turbo project and the vehicle is a '99 4Runner with a 3.4L V6 (5vz-fe). I plan on running 7psi and water/meth injection.

I'm trying to figure out the best way to return turbo oil to the oil pan since I've never done this before. At the oil pan, am I better off using a bulkhead fitting? Or should I use a punch on the oil pan and then tap some threads into the pan material?-

I know some people weld theirs, but I won't be doing that. I plan on taking the oil pan off the truck for this procedure.-

Also, am I ok using a generic eBay oil return kit to gravity drain the turbo back to the pan? Before anyone flames me for using eBay parts, I am using name brand for the important stuff (Garrett T3/T04E 57 trim turbo, Tial 44mm wastegate, etc.).-

Thanks.-

Any reason why this bulkhead fitting wouldn't work?

While I used a welded on bung, I don't see any reason the fitting in your link won't work.

No-name AN fittings are MUCH harder to assemble and more likely to give you a headache than the genuine article. On the other hand, the generic kits sometimes have hard to find fittings for less than what you'd pay for one brand name fitting at Summit, so at worst, they can be a decent starting point.

I think with a bunch of red lock-tight on the threads, maybe a dab of permatext on the teflon washers (to seat against the pan), and I should be good.
