oily air filter

[paula]

hi

not too sure if this has been covered, I looked through some of the 170+ pages!

my moggie 1000 is leaking oil somewhere! I'm not mechanical so please could replies be in basic language

it's been suggested that the rebreather pipe is spewing oil into the air filter, but is also leaking into the engine & out the back end too, & fuel efficiency has fallen off dramatically!

Unfortunately the older mechanic at the garage we go to has now retired so the younger guns are responsible for maintenance & it would be good to be able to go to them with some thoughts as they were not sure

Cheers

Paula

Sounds like your engine has a LOT of blow bye (the piston rings) and is pressurising the crankcase. Quick check - hot engine idling - take the oil filler cap off and rev up....is there a plume of smoke/fume?
