i recently checked my oil and it now has a litre of oil too much in it! i know i havnt overfilled it but it also smells of fuel so has anybody got any ideas why this has happened? thanks in advance.

Dribbling Injector is one possibility

Are you checking the level when the engine is hot or cold? The level appears to rise when the oil is warm, for quite a few hours after running.

Are you sure the dipstick tube is clear of residual oil? The Scooby dipstick tube has a habit of holding a false level unless you clear it, either by blowing through it or leaving the dipstick out for at least 5 minutes.

I'd go for the injector o-ring leak too, fills the oil up quite quickly. If this is the case, you'd best get it fixed soon, or you may end up getting a hydraulic lock, Is the engine a little hard to turn over?

thanks for the replys guys, the engine was hot at the time so i drained some out as i didnt want to cause any problems i.e hydrolic lock, im keeping a close eye on it at the moment. the fuel ecomony dosent seem any different to usual (180 miles to a tank) so if it is a leaking injector it must have been like it since ive had the car which is about 3000 miles ago. thanks again.

A hydraulic lock is when the injector leaks fuel into the cylinder, filling it to a point when the engine can't turn over, as fuel doesn't compress.
This has the effect of forcing the fuel past the rings, into the oil. If it's a slow leak, then the fuel will get into the oil, without the lock.

Fuel dilution can be caused by a number of things, it wrecks the oil so change it.

There are a few possible causes.

Leaking injectors
Excessive idle time
Incomplete combustion
Cool engine temps
Short trip driving
Chips and mods
Restricted air filter/fuel to air ratio wrong
Worn piston rings - excessive blow-by
Fuel pump over fuelling
Seals/gaskets
Improper injector timing
