Broken Timing Chain N47 BMW E91. Engine Repair.

In this video, I posted a photo report on the repair of a BMW E61 car with an N47 engine that had a broken gas distribution chain. As a result of inspection and diagnosis, it was decided not to remove the cylinder head. All work was carried out on the car without removing the engine. I hope that this video can be useful to someone, otherwise treat with understanding)

Great video, how do you check if valves are ok please?

[@kat0197]

Great video. My rocker arm lifter are broken on pieces. Do I need to put new camshaft support??

[@vitaliyburnashov537]

Thank you) The old camshaft bearing can be left, but it needs a thorough inspection for cracks.. Always to evaluate whether it is worth it to risk and save or go ahead safely and replace

How did you go about checking if the valves were damaged without removing cylinder head? In a similar situation now with my vehicle.

[@mart43]

How much time did it take in total?

[@vitaliyburnashov537]

If all the tools are at hand, then one day is enough.

[@catalinmarculescu2866]

Did the pistons survive?

[@vitaliyburnashov537]

Yes, they survived.

[@mart43]

did you reseal the injectors?

[@vitaliyburnashov537]

No

I changed my chain at 130 000, now the car has 260 000 km. I hear a little rattle at startup but lasts only few sec. I also hear clicking noise in idle sometimes. Should i replace it again?

[@vitaliyburnashov537]

Hello. Did you change all the chains or just the top ones? Have the sprockets and tensioner been replaced?

[@MarinTheFirestarter]

@@vitaliyburnashov537 Yes they have been replaced.

[@vitaliyburnashov537]

@@MarinTheFirestarter In this case, I would think about replacing the chain, but first I paid attention to the upper tensioner, which is most likely. Maybe start by replacing it.

[@ignaciorodriguez5001]

What happened? Broke the upper chain and the subsuquent disaster? Sorry my friend

[@vitaliyburnashov537]

Quite right. moreover, the client's breakdown occurred when he stopped at the STOP line. That's the fate.)
As a rule, this breakdown is preceded by the rumble of the chain, but how often the owner always postpones repairs for later because of their high cost. After a breakdown, the price increases significantly.
