My car is running "rough" and recently started stalling sometimes when backing up (usually uphill). I topped off fluids today while under hood and saw "milkshake-like" residue on and around cap for coolant resevoir. Something tells me oil is mixing with coolant here - leaking head gasket? Does this sound right and is it a pain in the @#* to replace on this car?
