Tonight I went to the grocery store to get some supper
and upon return I noticed an unusually loud tick consistent
with RPM. Anyway, I've decided the place to start is by
checking valve lash. What I'm curouis about is the fact that
I thought my van has hydraulic cam followers, which I didn't
think were adjustable. However the rockers have the
adjusting stud w/ jam nut. So I'm curious is valve
adjustment possible? What is the proper clearance? And where
do I need to position the crankshaft for each cylinder? Any
advice would be appreciated. By the way I have an 85' GL
with a 1.9l. Thanks!!
