6.4 L oil pressure relief valve failure
Had my 2008 f550 engine rebuilt including HPOP heads cam etc. Spent $10,000 a month ago. The other day engine runs rough chokes coughs and makes terrible noise and stalls. Tow it back and they tell me needs turbos so I say ok and they do them then call and say engine seized cause OPRV stuck open need new engine. I feel that after $10K they should have check the valve and this is their fault. Any idea's?
