have been gradually sortin out my g60 / new fuel pipes / new engine mount / new thermostat / jabba s4 service to glader / k & n + modded box / cat bypass.
1. whats the best way to find a vaccum leak as my mpg never goes above 5 on the comp.
2. after being driven hard and in 4th / 5th and revs go down to 2000 rpm oil waring light/alarm comes on.
the oil prob has got better since adding wyns supercharge treatment to stop the oil becoming too thin at high temp
any ideas ???
