Yes, it is about a 1 quart can. I have a Reverso Brand pump that came from an STS kit to pump the oil back to the pan. It is -12 from the tank to the pump, and then -8 from the pump to the pan. I also have a small vent on the tank so that the pump doesn't create a vaccuum on the turbo at all. It has worked flawlessly for about 1500 street miles between this year and last year.I noticed the can under the turbo, is that to catch oil? Do you use a pump to pump the oil back to the pan? If so, which one do you use?
Here is a link to their website. I am not exactly sure what model it is, but it's for sure one of their gear pumps.
