Tom made my turbo look brand new but he sent me the wrong threaded center section. It's pipe thread and not compression...I can't thread my oil feed line in it now and I'm leaving tomorrow. Banging my head and frustrated. Been working on this for hours.

Those are not compression look on the line you twisted off and get the fitting from the line if it's not there go to Napa and buy another one not a bigge there buy a 3/8th NPTF to 3/8th inverted flare and you are good if you bought the right supply line

Same exact fitting that's on the old line cliff. The old oil feed line and the new one are identical. The turbo housing will not accept the feed line fitting. I tried it on the bench. It's def NPT. On the turbo housing. So weird.

Do you have the fitting or you trying to screw the line direct into the turbo ? you have to have the adapter fitting between the turbo and the line the line is flared and the turbo is pipe lol you are using the center hole

Oh. I get it now. There isn't a fitting. I guess he kept it on accident? It must have been screwed into the old turbo housing center section. I'll head to NAPA first thing tomorrow to get it. Driving me nuts. Nothing is easy. This coach better give me g forces when I step on the throttle after all this work and $$$!!!

Awesome thank you. Final question: what do I use to seal that fitting in the housing? Some sort of liquid gasket?

Don, you're right about never sending the fittings. I had no idea it was in there. Things were so filthy and sooty I couldn't really tell what was what. My first turbo r and r too but yeah in retrospect I wish I had paid closer attention and kept that fitting. Now to find the O Ring for the oil drain side (bottom) of the turbo. I'll check at my local McMaster carr and Napa tomorrow morning. You gents are always a great group bailing me out of countless situations. Thank you.

So I can't find a local replacement for the flat o ring for the oil drain side of the housing. Can I use a round o ring of the same exact diameter?

A lot of orings were round till they flattened in installations. Round should work if it can flatten out without it expanding past recess when tightening, the flange to be perflectly flat when tightening and not rounding or bowing the flange. Since it is a drain with no pressure, it should work if it meets above. Make sure it can handle the temp of the returning oil. Could be a oring that is designed for the encountered heat. Btw, on turbo drain on 6.5 gm diesels, the oring is round and flattens in use.

Round works in that spot ok under the air horn you need to watch it,lol that fitting you paid under 5 bucks for costs $23.00 from DD because it has a Loctite seal coating on it,you can use about anything on it except tape use a socket and tighten the puppy down
