smell of fuel in oil!!!!
Discussion
Fuel in oil means you are either way over-fuelling and causing bore-wash or fuel is getting past worn piston rings/pistons and into the oil. It may be your cylinders are worn and engine will need a proper rebuild. Are you getting any piston slap?
Over time your engine oil will become contaminated and thin out, this will eventually lead to crank bearing issues and bottom end will eventually start knocking.
You'll need regular engine oil changes till you sort it, might be able to save the bottom end (crank/bearings) this way and end up only having to change piston rings or the odd piston if you are lucky.
Might be a good time for a forged engine rebuild

When the engines cold the standard subaru map does run it fairly rich.
There will then be some fuel vapour entering the crank case.
If you do short journeys it will never get a chance to burn off and out the oil breathers.
Also not sure what year the car is but it is possible on the classics running side feed injectors for the lower oring to leak and allow fuel to pass into the inlet manifold and through the engine causing it to run richer and therefore fuel vapour into crank case.
If it were something worse you would also have oil usage issues

to be honest its a new car to me only had it a couple of weeks and bought it based on condition shown in photos, the guy i bought it off also offered to drive it down from bolton to help me out, so dont know a huge amount about the car.
it hasnt done a journey other than up and down the road just to see how she goes, once fully warmed up obviously.
she does have some piston slap when cold but this dopes disappear when warmed up and for a standard car, she goes really qwell, no hesitation or anything like that and pulls hard, no smoke from exhaust just the occasional pop now and again, which i presume is overfuelling, its a 96 wrx by the way.
it is completely standard down to the catted downpipe etc but does have a cat back exhaust and panel filter, thats it, literally.
for what i paid for it im not to fussed in all honesty, would like to get at least 6 months out of it though if possible before having to worry about doing anything engine wise, but if push comes to showve, then so be it.
just out of interest, other than a standard wrx engine of the same year, what other engines are a straight swap??
thanks again in advance
