a while ago my omega started to make a tapping (tappet-like) noise from the driver side head, this would usually go quieter when the car warmed up, I asked about this on VXON and someone sugested an oil change might help.

The car conked out and was towed into work and has now gone to a mechanic to be looked at.

He has said today that it has almost no oil pressure, I asked if changing the oil pump could help, he quoted silly hours for this job

where is the oil pump on a 3.0 v6

has anyone got any other ideas

thanks in advance

I dunno, but there's a lot of V6 expertise on here, so someone will be along to help shortly.

Don't know about the oil pressure or pump, but the tapping may be blown manifold gasket. Wouldn't explain the breakdown, though nor would low pressure in that head....

The oil pump is at the bottom front of the engine, sits around the crankshaft. You need to remove the aux and timing belt and pulleys. You also need to remove the sump pan and the upper sump to get to two of the fixing bolts I believe.

If the oil pressure has been low enough to cause enough damage for it to conk out I'd suggest an engine change instead of trying to fix this one. Have you had the oil pressure light on? Any other symptoms?

[theolodian]

I am not convinced that it is an oil pressure problem, but if it is then don't bother fixing just get a used engine if car is worth it.

latest update is they are quoting me 10.1 hours labour to change the oil pump??

Whats that equivalent to in pounds, could you do the job yourself for cheaper maybe worth looking around if that the case.

...and this is the oil pump.

Surely if you had NO oil pressure the temperature would have been well up?

[madmatt]

thank you everyone! especially for the photo's

the mechanics are leaning on me to get a second hand engine from the scrappy as they reckon the oil pump book time is 10.1 hours which equates (according to them) at £500 labour.

The temperature was normal when the car conked out (and immediately re-started) just a loud rattle from the left hand head toward the cam pulley

Oil pumps don’t fail very often on these engines. If you seem to have low oil pressure, I would check first the oil pressure relief valve (located on the oil pump itself) – if it is faulty it may be releasing the pressure, and the problem may be resolved simply by replacing the valve with the oil pump in situ.

However – you say the engine ‘conked out’. Low oil pressure by itself will not cause the engine to ‘conk out’, so if it did then this suggests that the engine already suffered some sort of damage (possibly as result of the low oil  pressure), in which case just changing the oil pump will not help…

It is possible that the engine simple seized, so it would be beyond practical repair, or even if the oil pump seized then it is possible that it snapped the timing belt – again, leading to substantial engine damage.

So it seems that a replacement engine is due…

Ask them how they measured the oil pressure......and what the reading was.

[Taxi_Driver]

Just my thought on this......if it was really hardly any oil pressure that has caused the engine to stop.....wasnt the low oil pressure warning light on? prior to it 'conking' out?

Also you say in a post that it restarted so carnt have siezed.....and a rattle from the cam area  :-/

Wouldnt be cam belt has slipped or tensioner failed??  :-/

[Marks DTM Calib]

Even when the pressure relief valve is open, you still get some oil pressure......unless the pickup is totaly blocked
