After my engine mysteriously going bang in fifth gear at approx 70mph(not exactly straining a 2L!) i have a constant smell of burning oil in the ventilation system. any ideas how to rectify it without shoving 50 magic trees in it!?
check where the heating system intake is,usually behind engine on bulkhead.rubber pipe faceing down.check around it.have also known slight exhaust blow to smell like burnt hot oil if near inlet hose fumes could be dangerous oil or exhaust
