Hi I am new to the forum and just needed some advice. I have a really bad oil leak on my Impreza. It is coming from somewhere at the top of the engine and I was just wondering if there are any common places it would leak from? its a 2003 Impreza GX Sport. It drips onto the exhaust and causes the car to smoke after a long distance or going at higher speeds e.g 50-70MPH.
Any help would be greatly appreciated.

 

probably the rocker cover gasket m8, its a well known issue.

 

The main area's Impreza's leak is rocker gaskets under neath the car, and they drip oil on the manifold, thats what burns and smokes.

Other common area's are front and rear crank oil seals. Front one isn't massive job rear one is.

 

I'd put (a small amount of) money on it being the rocker covers. They do weep and drip oil onto various exhaust components. ICP do a seal kit for both sides for about £85 and you're looking at roughly 90 minutes to fit.
