Valve Cover Breathers | The De Tomaso Forums

Guest

I have Moroso valve covers and two Moroso breathers, push-in types, and no PCV system.They work fine except they smoke and it�s a little smelly if I park it in the garage after a hot run. I usually let it cool down outside.

Even though the breathers use a long, snug grommet, the breather and tube pop off easily (leaving the grommet still on the valve cover). It's great for adding oil , but one side (the one closer to the rear) seems to fall off under full throttle launches.

I got a PCV system from Hall that looks pretty cool that bolts on to the openings in both valve covers with 2 nice stainless hoses. I haven�t installed it yet, but I have a few questions:

1 � Will I lose HP using such a system or is it too little to worry about?
2 � I don�t really want to make another opening in the valve cover to add oil so what would happen if I used just one side and closed the other � with a cap on the breather tube.
3 � Or is there an easier solution � like flat, light breathers that won�t fall off, or new screw-in fittings for the valve covers so I can screw in the breathers?

I'm curious about what others have done. Thanks for your help.

My hookup requires me to remove the rt cover cap to add oil. This stock cap has a hose going to the air cleaner, which routs fumes into the engine. Its flexible enough to allow the cap to unfasten (1/4 turn) & lay out of the way for oil changes without disconnecting the air cleaner hose.

You have any pictures of the screw in breather caps?
