Getting ready to install a set of Holley valve covers....want to pull crankcase pressure of both banks. What (AN) fitting size are people using? Welded or tapped in?

Dude_man

-10 welded

Unreal

1/2" barb welded. That way no fittings, or anything. Hose just pushes on.

RecMech

-10 welded with baffles

TurboVic

This^^^ on holley covers.

realcanuk

Drilled and tapped for -10 fittings.

Dude_man

If you're buying coated/painted covers, just drill and tap

Unreal

Or DGAF.

They are (crinkle black color). Are the Holley valve covers baffled?

Unreal

Yes they are baffled but the baffles don't go the full length of the cover, so just don't be dumb like me. Drilled a hole to weld and then noticed it wasn't behind the baffle. So welded it shut, then move it over to behind the baffle.

I don't care about looks so this is my crap box.

I used -8 from each of my covers. Each goes to its own catchcan with a vent

Do you happen to have an underside pic of that tap?

Unreal

No. Wouldn't be able to see anything anyways as it is under the baffle.

On the topic of using Holley covers, does anyone know if the new Tall Holley covers,will clear the alternator? Also does the billet tech offer more clearance than the stocker?

usmcpony

Just using a barb for now

Unreal

Doubt it, considering the normal holley covers don't clear the alternator.

Billet tech offers a pinch more clearance.

Ultrasport05

How did you ge them to fit in your car Unreal? I know the coil needs the small bracket to clear but I didn't know the actual cover didnt clear the alt

Unreal

Ground down the coil part until it fit. The boss for the coil hit the alt.

realcanuk

My Holleys cleared the stock alternator and the billet tech.

Ultrasport05

Thanks Unreal. Is there a way to space the alt on the top mount to make it clear? Just a thought as I d rather not grind
