Has anyone ever tapped the block on an ld9 to use as a oil return for a turbo? Im not exactly sold on the idea of using the oil pan and while my block is apart was questioning using the block instead.

that's what I wanna know lol. I just don't like the idea of my oil return being at the same level as the oil

The absolute best route would be to have a shop weld a 3/8 or 1/2 NPT (big ass) bungs onto the oil pan for you. That way, you can plug it if you have to, and you don't have to worry about leaks.

Im sorry I forgot to mention, I already have my return on the pan. I just don't like the idea of it. what I'm wondering is would there be an issue with draining it into the block if I can have it tapped?

Your turbo drain is gravity fed. By plumbing it either higher or at the same level as the turbo will cause the turbo to back up with oil burning out seals and bearings. Also if you tap into the block in the wrong spot you might be getting PSI which would really cause an issue. Draining to the pan ( the lowest part of the motor) is the ideal spot. The drain nipple should be as high as possible on the pan, if the line gets submerged in oil the turbo cant drain and will cause those same problems mentioned before, buring up seals and bearings.
Hope this helped.

If you search through this forum, you should find pictures of Skilz setup, where he tapped into the block for his return. I plan to run the same way, and will post up more picture when available. In the mean time, look thoroughly through the posts in the boost forum and you'll find skillz's setup.
Am I ever glad I'm running a Borg Warner turbo, or I may have actually felt inclined to let you test fit my ish
lol. I'm going to pm you (Chris) in a bit with some questions about HPT, before I decide if it's worth my time to purchase it, versus, paying lots and lots of $$$ to have someone rape my ECU.
yes mark i know that but thanks. that looks like a really good spot to drain back to into the block. im gonna have to go down my machine shop and mock it all up while its apart to see if that will work for me. i just dont like draining into the pan on these engines due to having such a shallow sump.

i honestly do not understand the want to tap the block for this. the oil pan has worked for so many people without issue. i could see it being a bit easier for the automatic folks though as its so tight back there... thats for sure.
however...
id be more worried about the crank getting wrapped with oil and losing hp due to windage versus dumping the oil in the pan. and furthermore i doubt the oil level is clear up to the top of the pan where the oil return bung should be.. at least when the engine is running, anyway. if it was you would have people with drainback issues popping turbos all the time around here and thread with people complaining about it.

I have a windage tray. 2.3 oil pump swap

right but it wont be as affective in the instance because you are dumping the oil higher up than the tray. you'll basically be dumping the oil right on the crank from what i can tell.
now maybe missed something and forgive me for not knowing a whole lot about boost setups but i still dont understand what the big deal is with using the pan. if it works just fine for others, why change it?
