So today I think I have finally gotten to the heart of the matter with this
engine. I tried to spin the oil pump to get oil pressure coming out of
block but no oil would come out. Finally I traced the oil passage down
through the block to the filter flange itself. I had already taken this
off once and inspected it but not knowing how the oil system was supposed
to work, I looked down this one passage and saw what I thought was a plug
to block it off and didn't think anything of it since all of the other
passages were unblocked. What I think I understand now is that this one
passage that goes from the filter flange up into the block and then to the
head is a check valve? I am assuming that once you build up enough oil
pressure it will open this valve and allow oil to travel up to the head.
The valve would prevent oil from leaking down when you turn off the
engine. I am thinking this valve is malfunctioning and not letting any oil
come through. I pulled the oil pressure sensor that is above this passage
and blew into it and air came right out of the block no problem. So the
passage from the filter flange to the head is fine. It just seems that
this check valve is stuck or blocked for some reason. It looks like it can
be removed with a torx tool so I may try to remove it and see what is going
on in there.
I did pull the cam caps as Skipper suggested. They looked OK until I got
to cap number 4 and then I got concerned. The others had light lines on
them, but number 4 is really scored. I am going to try to get a new head
from the rebuilder to replace this one.
I sent them an email. I will let you know what their response is.
