My ex-son in law was driving my daughters 850 when he hit something in the road.
The radiator needs replacing and I thought that the head gasket blew but it was the exhaust gaskets. So now we have it all back together and running better than ever, an oil leak started. It was dripping from beneath the oil pump flange so I replaced the oil pump seals but the leak persisted. A friend told me to check higher on the block for a leak since the leak doesn't start immediately. It is very hard to see the block at all with the intake manifold in place. I think I found a leak at the thermostat housing. I didn't use the original bolts to reinstall it so I think they might have bottomed out and failed to seal. My question is , is there bolt holes that need to be sealed to hold the oil pressure elsewhere on the head ? I know that the exhaust studs seal the water pressure.
Thanks for all help !!! rkmacman 94-850T 98-V70XC FWD 84 Iveco Truck
