The lifters quickly silenced themselves after 30 seconds and I couldn't find any leaks after that.
Awesome to see her up and running. Break-in period, always seems to take forever.
Quick question, did you end up using OEM lifters? I remember a post where I thought you might have mentioned using the GSC no-tick. I currently have those in my built head but going to switch to OEM as well.
you are running very very similar built like me
How did you address the crank case pressure?
Did you enlarge the outlets on the valve cover?
As I can see from the pic you run 1 OCC?

The short answer is, I haven't lol. I'm running a single open catch can to both sides of the valve cover knowing that it may not be enough. I will also run a dipstick spring just in case.
From what I understand, the best way to address this problem is to tap the block itself where the balance shaft used to be and run at least a -8AN line from there to a closed catch can in addition to connecting the valve cover lines to that same catch can. If tapped in the right location, the block won't push a lot of oil into the catch can and it could fix the crank case pressure issue entirely. The closed catch can would have a line that runs to the intake pipe for suctioning out crank case pressure before it can build, but that's where the double edge sword comes in. The more restrictive your intake filter is, the more suction you will get out of that intake line, but the less power you will make. The less restrictive your intake filter is, the more power you will make, but that intake line to the catch can may do hardly anything at all
Taken from n2oiroc's post:
The problem is, every engine is built differently and depending on what happens to me is going to determine how far I need to go to address crank case pressure.

The STM sealed catch can will address any crankcase pressure issues you have. If it doesn't, you have a loose motor and the builder should be slapped up side the head.
As I mentioned, my build was identical to yours and I ran into crankcase pressure
with my FP Black. I noticed oil in the compressor and on occasion I would see white smoke out the exhaust when I shifted. To elevate this with my new set-up I opted for TSCOMPTUNED option of having the valve cover breather drilled and tapped out to a 5/8 fitting. Worked for me, no issues whatsoever.

That is also my belief. I always thought that crank case pressure had a lot to do with how the motor was built, boost going past the rings etc.

Very interesting! Are you running a sealed or vented catch can at the moment?

I does too an extent. Even a good engine has 7% leak down, and you're compressing a decent volume of fuel/air, especially with forced induction. There is going to be crankcase pressure. As long as the motor is good, it comes down to an effective crank case ventilation setup.

I run a sealed Radium catch can at the PCV, but my 5/8 fitting on my valve cover is exposed. I get questioned a lot on it, but that is how I was instructed to run it.
