Thread: 2.7 and 3.0 Td V6 Crankshaft Bearing Failure known manufacturing fault

My suspicion is it will be to take car into workshop for duration of customer’s free coffee, adjust tools in drawer - and then return car to forecourt with double thumbs up - nothing to see hear - keep driving.

How does the saying go? "oh ye of little faith"
(ha, ha, ha.)
Might have to agree with you though!

Not saying that the indicator is low oil pressure but it wouldn't take long to connect a gauge, possibly in place of the pressure switch.

This is what they do, taken from here DISCO4.COM - View topic - Korean AJD-V6 Crankshaft Recall

My crude translation of the ‘report’

Does sound like an oil pressure test sequence to me given the “rev, idle, repeat” statement. Presumably they are looking at the pressures to spot loose caps or worn bearings that would lower both max pressure and idle pressures (but not so much as to trip the low oil pressure indicator). (Complete guess obviously)

How does loose or worn bearings reduce oil pressure?

The oil escapes faster than it should thereby preventing the maintenance of a higher pressure.

I guess that test would be absolutely reliant on having the manufacturers specified oil and viscosity in there.
