alloy valve covers

[RIDE:42]

Bought some alloy after market covers but they have no outlet for breathers? As all i have been checking out on the net .
So what are others doing drill and fit breather hose?

Drill and tap, or weld on AN Flares.

I'm selling NRE Billet ones and they have NPT thread in them. So do the Katech ones on the car.

I was thinking just drill and tap but all the other ones are the same with NO holes MUST be a few cars getting around with sealed engins?

Or those breather oil cap things?

I reckon there is a few sealed engines around :s can't be good for them.

I would drill and tap. Do it in SAE so you can use ORB fittings and they screw in flush. 3/4 -16 for AN-8 and 7/8 -14 I think for AN-10 ORB

Ride 42, what brand of covers did you get? Are they tall or stock height?

Drill and tap em Jamo or run a breather on your oil filler cap. You dont, your gonna start leaking from all your seals

Yeah, especially with all your blow-by
