Default Oil drains in a 5.3 twin turbo build. How do I weld in AN fittings
So I just got the 5.3. I'm getting an LS1 pan for my thirdgen swap. I want to install the AN bulkhead drains in the pan. Do they make aluminum fittings to weld to aluminum? I have only seen the steel ones

I had the timing cover off of mine and there is a good spot on the pass side of the balancer I just drilled it and got a 90*an to pipe thread fitting tapped it 3/8 npt and it works good.

Ok great. I'll look for a weld in aluminum bung to weld in the pan..

I need two drains for a twin turbo setup that's why I chose the pan

If the pans coming off you could drill it and use a bulkhead fitting and not have to worry about welding

I used a -10 bung from Jegs and welded it on the inside.

A bulk head fitting is one that sandwiches the pan between the fitting right? Would it come loose or leak over time?

LT1Ray- I like the 90 degree fitting with the barbs. Any chance you have a part number handy?

My setup is as low on the pan as possible since my turbo is mounted low, works perfect. I used Jegs part number 555-110073 pushloc fittings and for the pan 800-8108. I used -10 pushloc hose from Jegs as well.
