"Well I got curious last night and went out and pulled the
injectors. When I
took the injector lines off they did drip fuel so they must
be getting fed.
I did not check one while cranking but will tonight.  I
pulled all four
injectors out and did a compression test and it ain't great.
Range from 320
to 380 so the new question is is that enough compression to
say the valves
are working? Should I expect more compression with new rings
that have not
had a chance to really operate yet? I'm trying to picture
everything in my
goofy head and keep thinking if a valve stem is bent it
would not  lift the
valve so the valve would stay closed which would mean it
would still build
compression in the cylinder but would not allow anything in
or out? Hoping
that thinking is wrong.  Bear with me guys I'm learning but
it takes me
awhile. I have to lay awake at night to work up these
questions :)

thanks,

Bart
Compression good enough to run with glowplug start  I think.
BUT bent valve syndrome would mean they stay open rather
than shut as its the shank just behind the valve head that
gets bet??? I think...
Take rocker cover off and check for an excessively loose
tappet/camfollower.
Is it hydraulic tappets.(I cant be bothered t oreread root
of 'Q'
My hydraulic system would not recharge after renewal as
engine not crsanking fast enough.
Try a little easy start/WD 40 maybe!
