Hello guys, I am EmKay, a new member in this community. I have problem on my 318i 2.0 E46 N42 engine. I have sent my car to workshop to repair the water pump because of leaking (the mechanical seal worn out). However, after the repair, I noticed the engine become too noisy and make make me wonder what was actually happened. It is very hard to describe about the noise. Can any one help me on this?
