That doesn’t work. That pump won’t pull enough vacuum to overcome positive crankcase pressure. I tried this on the old monster engine. It didn’t pull any measureable vacuum under boost.I need to come up with a plan to finalize the pcv system in this build.
Currently I have no baffles... Bad idea lots of oil issues. I also have my oil return from the turbos dumping into the driver valve cover. Another bad idea, I think I may be getting some aeration of the oil. After a few pulls or a long drive my oil pressure begins to drop, nothing crazy just something I noticed.
I plan to move the oil return to the oil pan.
While I have the valve covers off make some baffles, now my issue is that I want a closed pcv system... This is fine under normal conditions but under boost I have nowhere to vent too unless I run a line all the way back to the turbos and use some kind of pump... I was thinking of using a gm or Ford electric smog pump for this purpose.
Thoughts?
I have decided to use an open can with a 10an feed from each valve cover, one of the covers will also have a pcv to a can to the intake.. the idea is that the gasses will get sucked up under normal conditions and under boost it can vent normally.That doesn’t work.

Well, you gotta do what you gotta do. I’m sure I don’t have to tell you that any oil that gets sucked into the intake stream is gonna increase the chance of detonation. Your catch can needs to be chambered to keep the oily-watery funk that’s gonna accumulate in that can from getting sucked back into the intake stream.I have decided to use an open can with a 10an feed from each valve cover, one of the covers will also have a pcv to a can to the intake.. the idea is that the gasses will get sucked up under normal conditions and under boost it can vent normally.
It is chambered, I also plan to run a mesh screen before the can to allow condensation of oil before the pcv. It should work out.... I think.Well, you gotta do what you gotta do.

Be careful. You were already having blowby with a tighter ring end gap.Gives me a chance to go over everything, I am going to re-hone the block with new rings. This will let me open it up a bit for more boost
Rings were already gapped for boost. What I mean is they machined the block with tight tolerances.Be careful. You were already having blowby with a tighter ring end gap.
