Took my car in for annual required safety inspection.
Advised shop that I smelled something like hot oil after driving awhile.
Mechanic said smell came from leaking valve cover.
Recommend that leak be fixed when I either was tired of it or when oil started to be noticeable under the parked car.
Said fix was cheap.
Mechanic is very experienced, skilled, and trusted. Great reputation. Mostly works on race, antiques, exotics, and high-end cars. Audis, and Volvos are the usual low-end of his trade. At the high-end are Ferraris, Lamborghini, Maserati, Lotus, etc. with Mercedes and Porsche in the middle. Wouldn't ask except he isn't a VW mechanic.
Does the advice sound right?
