New Product - SHARKVENT Crankcase Ventilation System - NO more Oil in your Intake!
Due to the many requests for a complete bolt-on Crankcase Ventilation System using the Provent I have developed a new product line for all 928s.
Introducing "SharkVent" Crankcase Ventilation Systems.
Below are some sample details and pics from various year models.
You can find full details for your specific year 928 at www.sharkvent.com or visit www.928gt.com and look under "Performance", then "Crankcase Venting".
Special Introductory sale pricing is available for the next few weeks.
Kits are shipping now, but there is an approx 1 week wait time for new orders.
A complete, simple, and highly effective Crankcase Ventilation System for your 928.
Self contained, no messy catch can to worry about!
Genuine Porsche 928 Hoses/Clamps/Adapters used where ever possible.
Custom Hand-crafted Powder Coated Aluminum Fittings for a Perfect Factory Type Fit to your 928.
Our SharkVent Systems completely eliminates any oil vapors going back into the intake tract.
Some of the benefits of preventing the oil from entering the intake of your 928 are:
Reduced oil consumption.
More power and better fuel economy.
Reduced tendency to knock or ping.
Cleaner intake tract, ports, valves, and combustion chambers.
The 928 Specialists 32V SharkVent System is available in 2 versions:
(See illustrative graphics below)

The separated Air Out is very clean and you can accomplish this in a couple of ways.
You can very easily run the "air out" back into the port on the air cleaner lid by "Y"ing it with the air pump bypass hose.
OR, you can be sneaky and hook up the air out to the air pump inlet hose. Then it passes the air thru the air pump system and out the exhaust. This method will give you more scavaging of the crankcase vapors (think vacuum pump).
On an 87-up the Air Pump filter hose is right beside the ProVent so it is Super easy to do this(see photo). We offer an inexpensive Air Pump Hose for the 78-86 that does the same thing.

DR,
I'm assuming you are tying into the stock drian back hose on the 16V. The stock hose is NLA (last time I checked) and somewhat fragile. It's a very simple 90 degree hose, might be worth looking into offering a good replacement over stock.
Time for a plug
I have a very similar setup on my supercharged 81 - works very well.

I have no problem getting that hose, the one in the pic came in 3 days ago. BTW, As you can see in the pic it is a little more than just a 90. This is the newer style hose that replaced the very early "single 90" hose.

But - if the hose is readily available like you and Fabio pointed out, then I recommend people replace it like every other 20+ year old hose on their 928

DR,
Very nice and an awesome addition to your product list.
Does this mean my GTS will stop smoking every time I hit the throttle hard?
Thanks,
Roger

They are also pretty cheap, if I can get some costs of the kits down in other areas (Making those custom fittings is killing the cost) I will start including one of those hoses pre-assembled with the Oil Return assembly.

Ok, I must be thinking of a different hose since I paid a small fortune for the one I'm thinking of.

IF the smoke is coming from the excess oil in the intake it will for sure eliminate the smoke, it will also reduce oil consumption in the GTS ... unless it is caused by Piston and/or valve guide issues.

I think it was around $20. I can't remember exactly but it wasn't something that struck me as crazily overpriced since it does have that special little curve to avoid the belt.

Hi Rick,
Of course, I haven't added the Variants on the product pages for that option yet, but you can always call me or Jeannie. BE sure to let us know if you already have the check valve or not.
If there is enough interest we also are thinking about offering a Kit with just the ProVent, Check Valve and Mounting Bracket for those that want to get and/or make their own hoses, fittings, clamps etc. I realize that the kits are pricey due to all the custom fittings and stuff we make here, plus using Porsche clamps and hoses etc. So if I can offer a "Do it Yourself Kit" to help out I will be happy to do it.

Dave,
Have you considered making a oil fill cap with a vent pipe instead of drilling the tower? (Like Louie and others have done?)
