Thx for the reply, i forgot to mention in the first post,i have already changed a sump plug and washer,and come to think about you might be right when i took the old one out i did feel a bit of a hold but in my inexperience i thought its just dust or something,but now i know ,def a new oil pan...you said will damage the engine,i take it its not a good idea to keep topping it up?
