Hi guys, after having my atmospheric catch can fitted for nearly 12 month post remap about a month ago it has started to blow oil out of the filter on the top of the catch can. From observation from drive to drive I have noticed it only seems to blow oil out heavily under hard driving. The car did get a service just before the remap with new filters and oil but I didn't fill the oil myself although an experienced car technician did. I have checked the dip stick and it is level with the full mark. My only conclusions are that a. It has too much crankcase pressure, b. there is too much oil, c. It's coming from the head.
Has anybody else had a problem like this before? The car is a S3 apy engine with 66,000 miles on it with a custom catch can that I bought off andrew@ald. It has 2 19mm inlets on the side and a top atmospheric breather.
