Hi Guys. I had the oil mist filter problem. Basicly car was smoking and loosing oil really badly. Eventually I changed the oil mist filter and cured the problem. The problem now is when driving the car. It stays in lower gears and power seems to be down. The garage have said cos it is struggling to go over 3.5 revs The CAT will be blocked. Because of all the oil going through the exhaust. Could this be the case.? any suggestions welcome. I have read on this forum. ppl have taken the cat off and taken a broom handle to clear it. basicly de-catted it will this affect emissions.?
