    About a month ago I fucked up and topped off my oil with 10w-30 instead of 5w-30, and I think the mixture of the two made my lifters start ticking really loud. I’ve already changed my oil since I topped it off with the wrong oil. What is a good way to quiet them down. Flush with ATF? Just...

    I haven't found any discussions about my current issue... I might've not looked hard enough but i want to talk about the issue i'm having with my current 04 325i M54 engine. There's this odd rattling/buzzing sound when i accelerate above 2000rpms until 4000rpms and then it stops, but as i'm...

    Hi all, my 2004 325i has been making a strange buzzing/rattling/'cricket' noise at around 1750-2000rpm. It's only audible with the windows down and It only happens under load; as soon as I ease off, it goes away, even if it's still in the above rpm range. The car seems to perform as well as it...

    My 2001 330ci makes a rattling/chattering noise while under medium/heavy acceleration. I have done all sorts of research and have read threads of similar cases caused from: broken exhaust clamp, heat shield, flex disc, vanos, tensioner, etc. but I'm still unsure. It is difficult for me to...

    :confused: Gents, I promise I've searched and read a ton of posts. My head is spinning from all the reading I've done, and I'm an editor and read plenty as it is! I've replaced my CABs and sway bar end links in an attempt to cure the clunking-rattling noise I've been enduring for months now...
