Hello,
Ive noticed a slight oil dribble from the larger pipes that go into the stock bov. Are these pipes under boost when driving?
Would this be a leak thats pushing oil vapour out? I don't have a boost guage and i havn't noticed a difference in performance.
I do however have a problem with it using twice as much fuel than normal. Could these two be linked?
I have already fitted a new o2 sensor about 6 months ago but it didn't make much difference to fuel economy. At current prices i get about 40-50 miles out of £20 with 'normal' driving ie. not booting it. I also have left the battery disconnected for a day or two and no fault codes before or after.
As always, any advice is much appreciated.
