Heavy rattling from timingchain area
Hello out there
I am new to this excellent forum. I live in the south of Sweden.
I have a E39, 540, -97, long mileage. A few days ago a sound ,hard rattling, occurred. It seems to come from the timing chain area. It hasn't affected the drivability but the noise is just scaring.
I suspect it's something concerning the chain guides.
I am looking for a description how to dismantle the chain covers or to get a hint of the mysterious rattling.
Can anyone help me?
