i have recently had to change my rocker cover due to leaking, sorted now but when i put the oil in i put to much in, i was ment to take it out but i forgot and have drove it for a bit, it was fine til the day after when the exhaust started smoking, i took it to my mates garage and we drained the oil, and put the proper amount in, my mate said dat there was dat much oil sum had gone in the exhaust, its stills smokes and im jus wondering if there anythink i could do to get it to stop smoking? and is there any damage i could av dne drivin it with excess oil in it? thanks
