so maybe oil is building up somewhere? i'll ask my garage to look for signs when they take the plenum chamber off, as i say its not like an exhaust smell, its almost nice, but very strong over 4k revs, im just worried something is about to go pop
i bought the car with no service history on risk, but gotr 2k off the asking price, subsequently found signs of side impact, hence i had everything serviced and checked, this is the last issue to check out, hope i can find the source
