Oil Pressure Question ... is my engine dead?

Does your car run with DPF? If not switch to ACEA A3/B4 5w40 oil and you will gain oil pressure. If however your car have DPF then use C3 5w40 oil. This is a low saps oil but with a minimum HTHS viscosity of 3.5 mPa.s and are superior to a A5/B5 oils.
 
This is common on the Ford Taurus SHO V6 Yamaha motors after 100k or so. They usually just drop the oil pan and change out the rod bearings. The oil pump is hi flow low pressure so any wear and the idle pressure drops when hot. I did mine in the driveway in about 4 hours. Found one of the bearings cracked. The Main bearings are usually OK and seldom changed.
 
Hello,


It seems that you have the infamous DV6 engine .

When the injector seals go south hot gasses from the cylinder make their way to the valve timing area (no gasket between the cylinder head and its upper part ...just some silicone !)

You can imagine the result ...

Usually injector seals failure manufests itself with with some gas/oil leak around the injectors(lifting the plastic cover at least once a month is a must here).The sooner you catch the problem the better.

Althought this may not be the case here, I'd have it inspected ( dropping the oil pan-preferabley- or removing the vacuum pump would tell if there was any deposits)...
There is plenty of info about this design flaw affecting severals brands using this engine...


Why was the oil pickup replaced anyway? I hope it was not an attempt to get rid of the deposits caused by injector seals failure...it would take greater efforts to do the job.
 
I'm not sure it would cause his low oil pressure directly but excessive carbon/sludge deposits could have caused excessive wear, I think his turbo would have failed before any oil pressure issues arose though.

If you have one of these HDi engines it's always best to just change the injector seals out as a service item, apparently number 3 is usually the one that fails.

The Volvo lads say that the fault is not so epidemic as it is in the PSA/Ford cars, wonder what oil Volvo are using and whether that has anything to do with it.
