whats the advantage of drilling out the baffles?

 

They're drilling out the baffles because they drilled into the upper portion of the valve cover to put larger vent holes in, and the metal shaving's get stuck above the baffle and could come out and get into your engine. IE, they're drilling them out for cleaning purposes.

 

okay, thought they were removing perminitly

thank you kind sir lol

 

That's about where I'm at, as my VC was finally completed and cracked at both -10an fittings and my VC is now but a paperweight.

Edit: Watch your clearance on that BS Inspection breather, as it's a tight fit with a stock frame setup.

 

Im running a 35r setup. There looks like there should be plenty of room. Im just at a point, I dont want to go drilling into the vc yet. So I will see if these two vents will be enough.

 

Oh, nice! I posted pictures in my build thread of what it looks like near the vent with a IX turbo/stock manifold and there is not much room at all.

I think you should be gravy with the two -6an head vents and the BS inspection -6an vent.

 

I'm thinking about adding the STM fitting to the balance shaft inspection port.....does it matter if you're deleting the balance shaft or not?

 

+1 on that question.

 

Yeah, I am running a FP green and a straight fitting was a no go and I couldn't get the 90 or 120 to fit either. I ended up using a 45 fitting and it clears the 02/DP flange by a very small margin.

 

EM, Do you run the fitting from inspection hole to drain on catch can?

I will be running -10an from rear of VC, -6an from side of VC, -6an from inspection hole, -6an from dipstick.

 

Why did your VC crack?

 

Yes, I have this catch can with the 2,6an valve cover lines and vented dipstick tube and inspection hole vent.

I am going to run it this way for a bit and see how it works. If this doesn't do the trick I will go up to 10an on the valve cover vents.

 

For what it's worth, I run the balance shaft fitting with no balance shafts and haven't noticed any issues, (not that I have any idea what type of issues to look for when running the fitting without the balance shafts ).

I initially tried to use -10an to 1/2" NPT fittings (tapping the VC to do so), and the tapered NPT thread was apparently too much for the magnesium and ended up cracking on both holes.

My solution was (after a new VC) to use a -10an bulkhead fitting. It's been a success thus far!

I ended up using a 150 and she fit! It's tight, but she fit.
