Engine blows oil out from breather...I5 20VT

[bsh]

A lot of oil out from oil seperator when on boost. Seems ok when driving off boost. Have this oil seperator from Porsche: http://www.s2forum.com/forum/showthr...rsche+breather
First I tried to connect it to a hole I made in the rear of valve cover and oil return to a high point in the sump. No good!
Then I tried to connect it to the big venting on the blocks left side and oil return to drain plug, but still blows out oil.
New bored diesel block with JE pistons filed to JE specifications. I know there is some people which have the same problems with the 5 cyl. What is the correct way to do this?
May I have destroyed a ring?

Thanks

You need connected to both the upper and lower of the block at the same time to the catch tank.

That one in that thread only has one input so therefore is no good or you'd have to join the inputs into the single input on the tank.

Is it ok to use the outlet in the rear of the calve cover, which I already have made?

Yeh, there's one on the ABY cover tht can be used.
