turbo oil drain urgent help needed

I think the picture highlights the cause quite effectively, its likely that the drain is submerged and that you need to get a flat bottomed sump, wouldn't be surprised if you would have oil pickup issues if you drove it.

Put the drain in as close to the sump gasket as possible.

Oh and thanks for the input folks knew this place would come up trumps

Have you considered fitting a dry sump set up? For an off road competition vehicle I would have thought that it would make a lot of sense. You would never starve the engine of oil no matter what angle the vehicle was at or how it was being tossed around.

I would make the right side longer, you may need to fit baffles to avoid oil surge if it was a track car pulling relatively high g's cornering but for your purposes it will probably be ok without. Maybe one to stop oil going up into the engine when going over yumps if there isn't already something in place.

Can you check the height of the pickup from the bottom of the sump and replicate it in your extended sump?

Capacity wise if you put in the standard amount into the modified sump and remark your dip stick you should have the level. You can then connect the oil cooler and plumbing then workout how much extra oil you need.

I don't think that method would be a good idea, if the sump capacity is reduced doing that will make the oil level higher which could introduce a whole host of other problems. I'm not familiar with this engine but where are the gallery drains (particularly with it mounted at a slant)? If the original oil quantity raises the level to the point of covering the drains it could cause circulation issues by reducing the flow rate back into the sump. The correct oil level is based on the heat rejection of the oil as well so reducing the sump capacity will reduce its heat rejection. The oil cooler will help but as you have said, additional oil needs to be added to compensate for that. I'd be fitting some thermocouples pre and post cooler and in the sump to ensure the oil is at the correct temperature.

That will depend on how its levelled off.

Either way he's on about putting the original amount of oil back in it, so the oil capacity won't change.

Looking at the pic in the first post it looks like the turbo oil drain would be below the oil level even with the engine at the factory angle? It's difficult to make out exactly where the pipe is going after it gets blocked from veiw by the sump.

Ok, if the sump is levelled by increasing the depth of the right hand side the sump capacity will increase which will mean the original volume of oil will sit lower in the sump than it should. If it is levelled by reducing the height of the left hand side the sump capacity will reduce so the original volume of oil will sit higher. Either case means the capacity change needs to be determined. The simplest way of dealing with this is to work out how the new angle of engine mounting is causing the sump to rotate and determine the position at which the oil level would be as it was with the engine in its original position. Then once the sump is modified a bit of maths should enable the correct volume of oil to be calculated to get the level into the right position thus making the level reasonably correct relative to the base of the engine block. The oil pickup pipe will also need modifying so that it sits level with the base of the sump, probably 6 - 10mm from the bottom of the sump.

Bear in mind that oil has an optimum operating temperature. Changing the volume of oil will effect the heat dissipation of the oil and may make it run at the wrong temperature. This is a problem I had when I stuck a six cylinder Ford diesel in a Range Rover - the sump had to be modified to clear a crossmember and lost a bit of capacity. This caused the oil to run very hot. The solution was a thermostatically controlled oil cooler. In this case, if the oil capacity is increased and the oil cooler is not thermostatic it may make the oil run too cold thus changing its viscosity and altering its protection capability and increase drag.

Would it be possible to route the turbo drain to the other side of the sump? Maybe backwards and over the bellhousing so that the drain enters the sump above the oil level.

I would suggest that you sort out the sump modifications and the oil capacity before going any further though.
