1. Owner should have tried to just change rod bearings and the caps. Old school way of polishing the crank if it had damage and then plastigauge it.
2. Problem was likely a result of not doing regular oil changes which will result in...
3. New engine having the same problem eventually if they continue not to change oil.
Did the oil pressure light flicker once the engine warmed up or was it constantly on even when cold.
1. Agree
2. It's probably right.
3. Oil changes will be done at 3000 miles.
4. Oil pressure problem completely went away. It was coming on ONLY when the engine is fully warmed up, and the engine was shut down immediately to preserve the internals.
belt ? is no belt in the engine
Loooool.... you misunderstood... this engine (BMW N55) has a timing CHAIN, not a belt... but the serpentine belt (AKA accessory belt) slipped off the pulleys and was ingested into the engine through the crankshaft front seal... it then got shredded and then found its way into the oil sump mesh...
@@CarInspected i understood that is the accessory but how it can enter ?...
I just check and see sellers selling guard for that part to prevent the belt enter... how the belt can go their ?
It's a known problem with the N54 and the N55 (some say that the N52 has the same issue). The oil filter housing gasket leaks, dripping oil on the accessory belt. The accessory belt slips and gets wedged between the crank pulley and the crankshaft front seal (there is a few millimeters clearance between crank pulley and the front of the engine where the crank pulley rotates), the accessory belt gets chewed up and then penetrates the front crankshaft seal (behind the crank pulley), it then enters the crank case and gets shredded by the timing chain and sprockets.. then it tries to get into the oil system via oil sump...
@@CarInspected thank you :)
