Yes. They work on '85/'86 valve covers. also.

The first prototypes went into Van's 6.5 stroker. Although it has a very custom external oil separator also, it allows virtually no oil to get to the intake. I'm anxious to see how well these work on an '85/'86 in a stand alone basis in a stock application. You will be the first...good or bad.

could you explain why I only need 2 for the passenger cam cover, and not any for the driver side? curious.

These oil baffles are for 32V cars only? I couldn't figure that one out from the original posting

In an sense, you only absolutely need a valve cover breather for each of the valve cover openings that you are using for ventilation....either to the intake, to the air filter, or (heaven forbid) the atmosphere. Technically, on a stock S4 you really absolutely need one breather from the rear valve cover breather elbow to the intake system. However, slowing down the air/oil vapor that comes from the filler neck (front elbow) helps (note that the entire plenum of the cylinder head is open from the front of the valve cover to the rear)....since the sooner you start separation of the air/oil vapor the better.

If you are venting from the driver's valve cover (like a GTS did) you should put a separator over there, too....that's a "vapor" exit over to the passenger side of the engine.

Because so many people have done so many different things to the valve cover vents, I decided to not sell these pieces in pairs. They are literally separated in two different boxes and marked with either an "O" or an "H"....which reflects the letter in the word "Porsche" that the vent is going to go under.

So, if you are in the super economy mode on a stock S4, you would want to install one breather under the "O" at the rear of the passenger valve cover. (Noting that it would be better to put one under the "O" and the "H".)

Simply look at your engine, count the letters where you have an elbow, and order the amount you need, using either an "O" or an "H".

Yes, these are for the 32 valve engines.

The two valve engines handled ventilation in an entirely different manner.

Hi Greg,
I would like a set of the valve cover breathers for my stock 87 S4. I'll email Mary directly.
Thanks!!

Id love the breathers...but, if I install them, Id leak for sure.

I dont leak now.

Just curious about the machining needed to fit the breathers.

Is it something I can do with a Dremel in a shed or should I have someone like you do it with better tools?

Mr. Brown, I cannot find the valve cover baffles in your eBay store. As a matter of fact I can only find two different items listed. Where are all the other products you want to sell?

Dang it, those Chinese and Russians copy everything!

When Mr. Brown has an eBay store I cannot understand why he do not list all the items he has for sale. Mr. Brown is always telling us how much money his business is loosing. Getting the eBay store to work hopefully will get it out of the red.

Greg, I can appreciate the work needed to move facilities. I just moved 95% of my old shop to new shop - a new building with bigger space, better lighting, and 1.2 miles away from my home. My Ram 2500 6.4l gas will thank my wallet for far reduced fuel expenses! The other 5% is my heavy air compressor and dust collector and blast pot, and the associated piping. I have discovered Media blasting drives metalwork and metalwork drives media blasting; 2 beasts always needing to be fed and attention rendered. However, metalwork has been continually pushed back due to the time and intensity media blasting demands, so, I am doing no blasting until the 73 Alfa GTV, 66 K code Mustang are done respective of my lane, and the 68 Camaro is not on that hit-list as it will linger on a bit more.

You said you are studying ways to separate oil/air in an above posting in this thread. Herein is my above preamble; you know I do media blasting, my air compressor synthesizes your exact desire; it, a Sullair 50 HP motor pulls in vast quantities of air, compresses it in its Vanes and floods this air into the oil tank creating a frothy mix then forced into a separation chamber breaking these bubbles up releasing me 175cfm of air - at any PSI I chose. I am certain you have not 'missed' this analogy in equipment we all (well some of us) have around us - I know I often neglect the simple things right in front of me.

TschuB!
