Losing oil????

[litchy]

Got a sk+ charger fitted on a e46 330 (zhp). I appear to be losing oil from the engine, just can't tell from where at the moment. May be related to the charger. I am getting a smell in the cabin, which appears to get worse when stationery. I have changed the valve gasket but no improvement. Any thoughts would be much appreciated.

Did you change the small round gaskets around the spark plugs as well?

Didn't to be honest, why have you known them to leak oil??
