So I bought a Cusco catch can I've been reading it should be vented?

Should I drill and tap a hole on the top and put a filter on it?

Any advice or should I return this.



I bought it because after I go wot like 7500K and let off the throttle i blow some smoke.

Nothing when I'm on the throttle though.

Thanks in advance
Anthony

 

Probably depends on your current mods and how much power you are making.

 

Depending on the color of the smoke, a catch can vented may be the least of your worries. You could have a bad head gasket or it could be oil you're burning up

 

I would put a breather on it.

 

It's not the head gasket. Every seal was replaced. If it was a head gasket I would get smoke at wot too.

Its a light white smoke when I let off the throttle. Only happens after a long wot pull.

I make 350/315 on a bbk
