Hi,

I am running aluminium heads (Edelbrock) with nice components around (performer rpm intake, nice cam, super comp headers) which make my 289 verry happy. I am still using the stock valve covers and my mechanic suggests me to upgrade to "baffled" covers to avoid leaking/sealing problems. He says it would be a nice to have and he would feel better if I go for it.

What does baffle mean exactly? How much does it cost?

Thanks!

 

Most valve covers are baffled, its simply a piece of metal under the breather port to prevent airborne oil form going into the breather cap

 

It may also be a labyrinth sort of thing under where the PCV plugs in. If the liquid oil mist component is not separated away from the oil smoke vapor before it gets into the PCV, the engine will suck down oil and produce smoke at unbelievable rates (a quart of oil lost every 40 miles is easily possible). Guess how I might know this . . .

The baffle prevents liquid oil from going out the valve cover vent/pcv valve.
