[s-cars] Subject: Re: Valve cover baffle?

[Dave Ellis]

The baffle is there as an anti-frothing measure.

In the winter if you make lots of short trips and the engine doesn't 
warm up it reduces the amount of frothing that will form in the valve 
cover when water condensation becomes whipped into the oil.

The '87 Fox I had many years ago came without the baffle and adding it 
significantly reduced frothing in the winter.  Mind you driving long 
enough to let the engine come up to temperature and boil off excess 
moisture through the PCV system will also do the trick.  :o)
