Should I drill a hole in my engine block?
#102
So this was an epic failure. Sucks about 1/2 quart per auto-x into the air oil separator, separates the oil from the air, then fills up enough to just suck on straight oil. I'm switching to just a filter for now but the end game I think it going to be copying the setup that I said was stupid a few pages back and run the hole in the block to the back of the valve cover. I still think there's some merit giving the gas and oil a 2 way street on that drain port. Another problem must be that the check valve I put in the oil drain line on my AOS doesnt allow the oil to drain, something else I'm going to check. I really should just put a container on it as a drain. Its literally the only thing I need to dick around with this weekend.

I drain back through the turbo oil drain. I think the drain is just too slow because of the check valve. The car smoke screened less when longer time between runs. Still the whole point of drilling the hole in the block was to not suck up a lot of oil into the catch can. I should have just copied the bundy setup.

Did you simply T the catch can in place to the oil drain?
It's a big no-no on the GM trucks that use hydroboost brake boosters that run off of the power steering pump to T the drain lines. You need to buy a special power steering pump that has dual return points, or fab up your own solution with a remote reservoir. Not doing so can cause all sorts of interesting problems when you try to use the brakes and the steering.
The turbo oil drain should always be full of oil from the turbo. When your catch can tries to drain into the T it runs into a solid flow of oil and can't drain.
I'd try draining it to the dipstick and see what happens.
