the knock your hearing is probably injector knock from the long lead injector.
it sounds like you either have low fuel pressure or oil pressure.
fuel pressure relief could be worn out, weak fuel pump. need a gauge to check.
can pull the icp connector off, if oils coming through replace it.
then you could also replace your ipr, it could be malfunctioning not giving enough oil.
