View Full Version : Check out the sludge in my M73! board57796 02-10-2007, 04:04 PM Took my intake manifold, valve covers off and saw this! Holy poop. Hopefully I can get it all cleaned out. http://bimmerboard.com/forums/posts/314657 Anyone wanna help me shovel that out? :eek: AlarmedBread 02-10-2007, 05:42 PM yikes...fun stuff good luck with the cleaning, think you'll need a couple 5gal. buckets of solvent to soak those bad boys in. One of mine had similar residue in the afm,throttle body and intake manifold, it had a cone type filter. The other car has used the paper filters all its life and has no such residue. Not sure what you're using just sharing my experiance with road grime and sludge inside engines :) fsmtnbiker 02-11-2007, 08:12 PM Yuck! Was the engine overheated, or were the oil changes just not frequent enough? That is terrible! board57796 02-11-2007, 08:51 PM Yuck!

Overheat :( fsmtnbiker 02-11-2007, 09:17 PM Does that motor suffer from the same HG problems that the M70s do? Was that the cause in this case?
