I've just had my car tuned and ever since then the car has started to produce far too much oil from the breather system. I have a no name breather system plumbed in with all correct connections.

Before tuning there was no oil being dropped from there at all so it vented to atmosphere. Today i just fitted a small pint milk carton too see how much was collected. Went for a little drive into town to do some odds and sods gave it a little stick on the way home and it had half filled with oil.

Its only running 165bhp chip filter exhaust uprated i/c. At a loss as to what might be causing this.

 

Sounds like piston rings have gone mate, now that you have had it tuned i'm guessing your running more boost? If so it's getting past your worn rings and giving you high crank case pressure forcing oil out
If you didnt have the boost turned up then maybe your tuner has leaned you out too much and you've just fried them

 

It was tuned by Chris Todd at TOTD but it think i have traced the source of the trouble. The breather pot that i put I'd plumbed it in wrong. In my infinite wisdom I'd put the large pipe back that I now think vents to atmosphere to the oil/crank sump return leaving oil to spew everywhere.

So its now looking like small return pipe to oil drain. Large pipe venting to my technical milk/catch tank. I'm hoping this is the cause of troubles.
