[Vwdiesel] re-ring done, but no start

[Bart Wineland]

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
