So it's a broad thread title sorry. But I'm wondering if any one has got any way to explain why my engine is so loud. Off the top of my head I wanted to guess lifters but have read through a few posts that tell me the 530's (94) don't use any. So I'm wondering fuel injectors? Because I've heard those are rather loud. It's not a consistent ticking or anything, just seems like the crankcase is making more noise than it should. And i'm sure the immediate response is that hey, jake... your car is old and that's what happens at 230k miles, but I'm just looking for some info. Maybe I'll get around to a rebuild next summer.
