my93 had its mot on Saturday which it passed i may add.however they did find an oil leak which seems to be coming from the left side of the block and dripping down onto the exhaust giving a lovely burning oil smell.i asked the guy what he thought it might be and he said he could not tell unless he took my timing belt cover off to have a look.another guy in the garage said it was more than likely to be my rocker cover gasket.one thing i have noticed it i appears to be getting worse.
