hi guys, over the past few days when i've been starting the car from cold in the morning and theres been a slight tapping, knocking noise coming from the engine. anybody got any ideas wat this may be? i guessed it could just be the hydralic tappits as the oil hadnt circulated to them. its not a loud noise but it doesn't sound normal. as its only started in the cold weather i'm just hoping its nothing serious.
i also had to top up the coolant today because it fell below the minimum and flashed the warning light on the dash. are there any particular areas i should be checking for coolant leaks? there haven't been any patches underneath the car from a leak so where could it be going?
thanks in advance for any help.
