As always, IAT sensor was covered in sticky blowby gunk.
Cleaned it and will be installed with new o-ring.






Although I’m not going to re-use these spark plugs, they will provide
some info as I decided not to carry out the compression check or
even the test driving session.
The one at #2cyl looked to be showing lots of powder like deposit so something
to be looked at when inspecting the head gasket.




The moment of truth.
This was how the rear valve cover gasket was installed.





Caught and trapped meaning there was no seal at all in this area.
No wonder why the area was covered in so much oil.


I’m glad that it was not cut in pieces by the rocker arms or cam shafts.





As reported earlier, many gaskets/seals were missing from the TB covers.
Nothing on the lower and rear covers.




Addition to this, there was big hole behind the crank pulley as someone
didn’t bother replacing it with new one after the pulley failure so as a result,
the TB area behind the covers were really dirty.

As expected, there were lots of oil/wet marking on the TB rib so glad the
owner decided to take my service now.
