If you are building a 22RE turbo motor you shouldn't tap into the existing oil holes below the oil filter because that is unfiltered oil. You should drill a new hole just to the left of the filter, there is a flat spot there, this could be the spot where the 22RTE's get their oil ? If you are running it out of a oil cooler sandwich adapter you should make sure it's filtered oil. If you actually 4x4 with your truck drilling the block out so that it drains where the 22RTE's drain wouldn't be a bad idea either, if ur gonna be side hilling for a long time, because an oil pan drain could be under oil.

One other option is to add an in-line fiter in your oil feed line.
I've found that there is a huge diffrence in quality between oil filters.

I ran my oil feed from a remote mounted oil filter housing to get filtered oil but i just pulled off my second turbo with a bad shaft. It seems to be scored heavily but the inside of the of the bearings do not look so bad. I was going to send out the turbo to be rebuilt and see if they can tell what happened. I was thinking of putting an in line filter also and that moroso one sounds like a good idea. I'm open to any idea's.
Thanks
bob

Bob, the turbo shaft is much harder than the journal bearings. Are there score lines on the inside of the bearing? Did you find any traces of debris on the thrust bearing itself?
Used turbos are a bit of a risk.. And used turbos that have been previously disassembled are even worse, as most people don't reassemble them paying attention to orientation, which impacts balance.
Myself and at least one other person on this forum run in-line filters due to previous problems destroying turbos. In my case, it's likely due to new engine break in debris.
If you get a filter, the things to pay attention to are how fine a filter it has (usually in microns), total filter area, and if it can be reused/cleaned/easily replaced. I've got an inline filter FS on this forum, it's filter was too small for all the crap I was passing through my motor, but it can be easily cleaned.
Running a regular oil filter in line works also - big filter element, don't have to change it often. Just be sure to buy a high quailty automotive filter - there's a huge difference between brands.

It looked pretty clean inside there. i did not want to disturb much so the rebuilder could tell. the 2nd turbo was new and did the same thing. the outside of the bearings were scored some but the insides didn't look bad. It is baffleing. I would think the bearings would go first. I cant imagine having that much crap passing thru the oil filter. motor has abou 25k on rebuild. Is a inline tube filter better than an additional automotive oil housing?

Moroso did some research and they found that anything smaller than 20 microns is not big enough to cause engine wear. So any filter that claims smaller than 20 microns is just making the engine lose oil flow volume. not ideal. this info was in a recent Hot Rod magazine or maybe Car Craft i get both.

I've had them fail both ways: Fail due to crap in the oil and fail due to crap clogging up a small in-line filter.
I have a theory that the oil going to the turbo is pre-filter... But I don't know that for sure.
For me, I now use a remote oil kit - a full sized filter just to filter the oil for the turbo. And a non-Fram filter.

Interesting...
I gave up Fram for ACDelco about 20 years ago. I've given up AC and now run a Motocraft FL400S filter on the Yota.
My local trans shop uses an inline filter which will bypass in case of restriction. I should find out the particle size it's designed for.

Fyi, the factory oil filters are the best. As are denso's if you can find them.
