The Y61 3L CRD has started blowing smoke, dirty black smoke on startup, sometimes looks white though.

157,000 kms.

Maybe using a bit more fuel, sometimes needs more cranking to start from cold.

Doesn't seem to be down on power but am noticing a more louder deeper drone coming from the front of the vehicle when driving.

I was thinking, clean the MAF, replace air filter and maybe fuel filter.

Any other suggestion are most welcome.

Thanks.
