oh that sucks. There was an occasional ping in the engine bay, most of the reverb noise was in the exhaust though. Best way to describe it was a metallic heart murmur ...... and it would come and go... sometimes the idle would be consitant and the car seemed to be o.k. , next start up it would be all over the place.

Come to think of it, besides the oil leak, the intake boot could be a big deal. I mentioned to raf and he was able to witness it, sometimes when I hit the gas to rev, it would be sluggish and almost not move the engine, the next, it would rev perfectly fine.... might be a vaccum leak huh....

yeah pretty much just as chad described. really leaning towards some sort of vaccum leak myself. mixed in with some oil leaks. possibly a bad 02. as well. but none of that is really too bad to take care of.

i am exhausted and have to be up in 5 hours. If you guys figure something out please post it and I will check in the morning. Thank you seriously for all the help, I am def feeling a little better. Thank you.

np we got your back buddy

get rest

Yep, sounds like you have big time intake problems. Pinging on M54s sounds like a very sharp tap, like a marble hitting the manifold. It'll produce that reverberation you heard in the exhaust, too.
Besides a leak, I would look at the DISA. It's not easy to do a DIY check, but if someone local with the BMW software can help you out, they can actuate the flap to tell you if it's working. The o-ring around is also a potential leak.

The good news is that it isn't atypical, so you've a pretty clear diagnosis path.

So odds are chad needs to replace his intake boot and some back lines to get rid of vacuum leaks. Then hopefully his CCV/DISA is good or in need of replacement without anything else being severally wrong or difficult to replace.

it definitly pinged a few times. id say like 4 not all at once but a varried times when it was running rougher it seemed and when the murmur wasnt as prevelant.

i have some spare intake boot parts lying around.

The pinging should be worst at idle. The more air the motor needs, the less of a problem a vacuum leak becomes.

But yeah, the DME will try to compensate for the problem, e.g. retard timing, add fuel, etc. It might fluctuate, or it might disable a cylinder, so it won't even be consistent if the motor is shut off and restarted.

guys, thanks again for talking this through. Def sounds like the right path. I am going to see if I can get an intake boot soon..... also going to source oil housing gasket... pretty sure my disa is shot too, I hear it clicking not long ago...
