Hi all, slowly progressing through removing the B (left)
cylinder head from my son’s '89 XJ-S. At this point we have
successfully removed the camshaft and are trying to remove
the tappet block. First question, I can see only the 6
socket head screws and the 6 nuts below the block. We have
removed all of those but the tappet block seems still quite
firmly attached. This may be because of the large amounts
of black sealer used to glue it to the head (factory?), but
we have tapped on it as hard as we dare with various wood
blocks and hammers to no avail. It seems like there should
be more fasteners at the front end of the tappet block where
it goes around the timing chain, are we missing them?
Second question, do the studs for the cam bearing caps go
all the way through into the head? That is, do we have to
lift the tappet block over those studs as well (which might
explain why tapping it from the side doesn’t loosen it)?
The benefit of any experience would be appreciated!–
