Hello this is Nico at Charlie’s Foreign Car and we have got a BMW x3 that has ingested a belt inside the engine of this car.  If you don’t know what happens, the belts start to fray the tensioners, the belt tensioner gets cocked off to one side, it starts feeding the belt it starts fraying the belt then it starts feeding the belt into the front crankshaft seal right into the engine right into the camshaft and gets into the crankshaft timing gear and then the car will jump time.  Luckily this car the customer caught it before cuz all the lights went on the dash and they had the wherewithal to pull over shut the car off and they saved the engine by doing that because usually this is catastrophic failure so down there you could see the crankshaft is down there and you can see there’s no crankshaft seal in it right now because it got torn to pieces by the serpentine belt being fed through that front crankshaft seal area this is actually part of the crankshaft seal itself right here it rips the crankshaft seal apart and then here’s the serpentine drive belt that got ripped apart just shredded in here it fed itself into the engine and the bad part is sometimes that it it’s directly in line with a timing chain right underneath there not to be confused with this oil pump drive chain the timing chain for the engine is right up here right where my finger is up there so luckily that didn’t happen onthis one here’sanother chunk of belt and it made it all the way down into the oil pickup tube and inside here there is also belt chunks that have sucked in right in through that oil pickup – it was ready to grenade down here we have the engine oil pan removed lots of small belt fragments all in here just lots of crud so we’re gonna clean all that out this is a 4×4 all-wheel drive vehicle so the axle runs through the oil pan this hole right here is for 4×4 x3s the two-wheel-drive does not have that the differential bolts right to the side of the oil pan and the axle goes right through it so what we’re gonna do right now is we’re gonna clean everything take everything apart get all the belt fragment out put all new gaskets on it put some fresh oil in it and start the car and run it and see what is happening with camshaft deviation numbers and also make sure that the vanos is advancing and retarding properly just make sure that we’re getting a change if the oil if a small enough belt fragment made it through the oil pickup.

Then it can but it has the potential for you know clogging those ports. Then we could have you know we could burn up a camshaft journal we could burn a crankshaft journal we could make the vanos not work all kinds of bad stuff can happen once we get it running we probably want to put fifty or seventy-five miles on it make sure that everything’s good with it again our cam correlation numbers crankshaft correlation numbers and then make sure that the vanos units are changing when we go and do a vanos tests go through the ISTA test plan on this car.  So we have this engine running and back together now on this 2011 x3 that has ingested a belt without removing the cylinder head by the way to kind of summarize what happened here the belt came apart and went into the front crank seal it did not jump time we pulled the oil pan and the valve cover down we picked out all the belt pieces the timing chain actually didn’t have hardly any belt pieces in it if any at all the oil pickup screen was clogged with it not totally clogged but it had some stuff in there we cleaned everything out renewed all the gaskets put new oil and a test-drove it and now we’re here we’re testing the vanos operation making sure that it is switching we do not have a clogged oil galley right now I could say that we’re gonna go put a couple more miles on it the customer wants his car back we’re gonna get it back to them and give it like a hundred-mile check afterward we’re gonna ask that the car comes back after 100 miles so we can just go recheck all this work and also get back into the ISTA so thanks for watching.

This Owner Was Very Lucky!
