Dry Sump

[4agedub]

Hi
On my type 1 I'm running a 3 stage dry sump pump. I think the make is bugpack or cb.

There is one feed line from the tank to the pump 3/4". Then from the pump there is a 3/4" pipe to the full flow port.

Scavage side theres the std oil scavage in the block, and a pipe from the sump plate to the pump. The return line is 1/2" going through a oil filter and cooler back to the tank.

The tank can hold + - 10lt of oil and has got baffeles. I use the same tank in my type 4 with a normal empi dry sump pump.

Now the problem is that I seem to get a lot of aerartion in the tank.... any ideas what it can be? With the engine just free revving the aeration can be seen on the tank side dipstick.

Please any ideas will help....
