PLEASE HELP...............'89 420SE rattle
When my 420 is warm, occaisionally there is a rattle when i start up. I think it may be somethin to do with the oil pump but i am not sure. This rattle stops as soon as the oil pressure rises to full. What can i do to get this fixed. I remember at some point having this on my 380 at some point which is why i think it may be a common prob. I cjhanged the timing chain and tensioner cos i thought that was the cause, but it wasn't. I also know it needs an oil change again.
Is it serious or will it not take much to fix it.
