Had trouble with a slow oil leak for weeks on my 8p 2012 1.6 TDI Audi A3.
My local garage couldn’t find this leak, as when ran on the ramp for over 6hrs there was not a drop, even running it at 2000rpm for 2 of those hours. The engine still ran perfectly.
Last week, suddenly my engine had no oil pressure, and bearly ran, therefore got it back into the garage, and when they took the sump off they found a crank main bearing cap in the sump, along with the bearing, which had been rubbing against the oil pump belt, causing fibers to come off it and block up the oil pump pick up, resulting in no oil pressure.
the garage is absolutely confused as to how a crank main bearing end cap found its way into the sump as they have never ever seen that before.
One of the Bolts that held the bearing cap was also found in the sump sheared.
now looking at a an engine change for the car, but wondering if anyone has any idea how this could even happen?
Thanks
Paul
