help w/ headgasket '93 90s

[mike]

I think the official wisdom is lock the crank and the
cams with special tool number 555. The cam sprocket is
on a taper not a key so you need to get a puller to
remove it.

There might be an issue with only doing one as some
people recommend re-tightening the heads when you
remove the valley and finally, there are some oil
check valves in there somewhere....it escapes me what
they do at the moment but I seem to remember they are
important and cheap so replacing them is worth a
thought. Other things to consider....TB obviously
alone with water pump and idlers, maybe thermostat as
well?

good luck with it

Mike
