anyone here who knows how to replace an oil pan for an 1990 audi 80 4cylinder model?

i recently got into an accident where a huge rock went under my car which damaged my oil pan and possibly my oil pump.

since then the oil lamp warning has been lighting. i really need the help...

do you have to take out the whole engine to get to the oil pan? is it that hard to replace the oil pan?

please help....

its kinda hard, you have to support the engine from the front and put something to support the tranny, then drop the cross member and you get a clear shoot to the oil pan and stuff.
Hard and slightly dangerous to do alone.
