this is what happens if you don't change your oil.

[all-mota]

a few quarts of oil and some tranny fluid should clean alot out and then he should drain a little oil out and pour some diesel into the crankcase and let it run and it will look new again

[roscoe]

Holy shit thats rediculous

[jdmdb8itr]

[jojeezek]

[jdm eg99]

[collins]

That should totally be covered by the manufacturers powertrain warranty

What kind of oil are you using? I am running Mobil 1 religiously changed at 3k, but I don't think my shit is gonna look like that @ 124k.

Royal Purple in the M3.

Ive seen this many times too. Short trips (engine not running at full temp for a prolonged period) can also contribute to sludge buildup. The problem is not just the amount of sludge, but the fact that the engine has likely been oil starved.

Looks like Genital warts on the second pic..

Oh yeah, LOL at everyone thinking seafoam or a detergent lube will clean this sludge out. Ive had to rebuild several sludged motors. You can run the individual parts of a disassembled sludge motor through a professional parts washer and still end up having to manually scrape the sludge off. Theres no PFM in a bottle thats gonna remove this stuff.

This is just what happens when you own a BMW, it fails.

my old Land Rover (when I bought it) WITH ONLY 40K MILES!!!

This was after 3 or 4 flushes with ATF, Rotella, and Kerosene. It was so bad that oil would get up into the heads and not drain back down. Lifters would hold oil and not drain it out.

The end result was cam lobes wiped out, cylinder walls scored, oil pump shot, and just about everything related to oil was shot.

I had to bore, put in pistons, bearings, cam, lifters, pushrods, rocker arms, and a few other little things.

Now, the oil I just removed from my 53 Chevy was on the other end of the spectrum. The car had been parked since 1974. It fired right up, but had a few carb issues. I had drove it for a few hundred miles ironing out the carb and a few other things. I changed the oil a few weeks back and it was like water. It also had 4 extra quarts, which was more than likely gas from the carb issue. This stuff smelled so bad I had to put it outside, it was stinking up the house from being in an attached garage.

wow i thot me being 500miles behind was bad...

I've seen waaaay worse. Literally pulled a VC off and the buildup was like it was baked into a mold the shape of the VC.

x2, I have seen that too. I worked on a 140 chassis Benz with the V-12. The lady said she was "too busy to pull over" when it started overheating. She blew both head gaskets and cracked a head. When I pull the VC to inspect it, the crud (solid form) was the shape of the valve covers. Craziest thing Ive ever seen. Needless to say, she bought a junk yard engine and sold it 2 weeks later, lol.
