Thread: KV6 - Brown oily sludge in air inlet

Half the price of the K&N with the same desired effect. Mine sounds awsome. You won't...

Many thanks chaps - I'll get searching.

Mg/Rover addressed this problem later on by recommending fully synthetic oil in the KV6. The last ZT180/190 models were fitted with Mobil 1. Change your oil anually with a top quality synthetic oil. Your inlet chamber and butterflies should never gunk up. A little oil in the inlet is common in all petrol engine cars, and indeed will keep the vis valves and all the butterfly mechanism lubricated.

Agh.. So it's not just me then.. with this oil in the throttle body. Mines a 2.5 KV6 in a 99 Sterling... Can anyone tell me why this stuff is vented into the intake system in the first place? Is it just me, or is this madness? Mmm.. This wouldn't be one of those environmental issues would it?

got same engine,you need like myself to fit a catch tank to stop oil from going into manifold think they are around ?70 or so on web.
