When I first got the Rallye I removed the open K&N and found the inlet pipe before the throttle body covered in quite a bit of oil. I cleaned up the throttle body and put on my Viper and 90 degree silicone bend.

Tonight I was under the car and noticed that the filter was again begin to get soaked with oil.

It doesnt really appear to be using a huge amount of oil, I've only had it a month, but my old '6 never had any issues in this area.

What are the causes of heavy breating and is it a potentially terminal problem if not dealt with? Could I just put a breather on the hose going to the inlet pipe to stop the oil being recirculated into the engine?

Thanks Darren

Possible worn piston rings would be one of my guesses......

These engines as standard should have enough breathing. I haven't been running a catch tank on mine and it has been running 380bhp without a breathing issue.

If they are breathing heavy there is a fault somewhere else which is causing this.

A catch tank is a way out of it, but you are avoiding the problem this way rather than solving it....
