Re: MAF sensor (oil on sensor)

Hmm.  Time to check mine...dang.  I'm gonna be rather annoyed if it's 
also dirty...

The fact remains that there are no engine components before the MAF 
sensor; how could it be accumulating oil?  Ack!

I guess one question is if it can be cleaned if you catch it early 
enough...the sensor Brandon sent me has unrepairable damage to the 
intake side of the platinum wire.

It might be possible that the burn cycle for the wire might actually 
cause more damage by forming hard carbon deposits on the wire, or 
there is an actual chemical reaction of some sort.

Either way, I'd still love to know what the source of this oil is.
