Hi Jeff,


My name is XXXXX XXXXX I am a professional here at Just Answer. I noticed that your question was not getting a response and thought I would ask to see if you still need help with this.

With what you have described here to where this happened suddenly like this here and your engine oil filter is only 1/4 way full as it should be fuller this sounds like a possible failed oil pump on the front of the engine.

The biggest issue in some cases is just the pick up screen/tube clogging and causing this but if this has been cleaned/checked already most likely it is o.k.It might be worth it to re check it again to make sure it isn't restricted.

I would also inspect to see if the pressure relief valve is stuck or has a fault as this can sometimes cause this as well.Usually you may not see a full loss of oil pressure if this were to fail but it is possible as well.

It is difficult to say for sure from here exactly what has caused this without seeing the vehicle but this is what I would check into to see if the fault can be located.

I hope this has helped in some way here.If you need anything else don't hesitate to ask thats what I am here for.

Thanks Pete
