normally 110 nueton metres. use nut lock and once you have torqued you will feel if you have to tighten it a bit more.

You should really go to an auto parts place and buy a manual. This something you really should not cut corners. It will give you the specs and the sequence of how to torque the head. You will also need to know how to set the timing in relation to the cam and crank. Manual is well worth the money. It has pictures, instructions, and such.

this is an oil pressure problem, either a sensor is not sensing enough oil pressure, or the high pressure pump is not building enough pressure(possibly leaking or head is leaking). this engine requires 450 psi minimum oil pressure at the injectors to actuate the injectors.
