bought a 1981 240 d about four months ago. as a preventative measure, had valve cover gasket replaced, head gasket replaced, all belts and hoses, etc.. and valves adjusted.
i seem to be going through a lot of oil, maybe a quart to quart and one half every 500 miles or so. i see no sign of leaks from pan. nothing on the engine or under car, except old oil i haven't steamed off yet. tail pipe seems like normal diesel emmissions. it runs very strong. is this normal? i have driven newer cars for a while and might have wrong expectations. but i plan to give the car to my son as his first auto and i worry that it is not right. can anyone offer help on this?
thanks!
