My 88 bmw 325is has a loud roaring coming from around the engine when i get to about 25-30 mph it gets worse when i turn left but doesn't when i turn right any ideas what could be wrong? also wondering how hard it would be to change out axels, shocks and strutts by myself?
also when i drive it for awhile and turn it off alot of engine coolant leaks from the expansion tank pipe any ideas?
The head might be cracked or the headgasket shot. A leakdown test can help you there.
