94 Subaru Impreza

This smell is a leaking rocker cover gasket
the result is oil dripping onto the exhaust which produces a lovely smell!

It won;t use much oil only around 1 teaspoon every oil change

the cost to have this gasket replaced is only around $120 new zealand dollars plus around $ 40 nzd per gasket - for genuine ones this is a very reasonable labour charge considering what has to come off to get att it.

It is also a wise idea to replace both at the same time

hope this helps

if I were you i'd get your closest subaru dealer to do it as they will ensure that every thing is tightend properly.

Thanks
