[tech]: help with compression readings...pretty please?

[abatzis2@hotmail.com (Michael Abatzis)]

compression on the new 16v rocc, which though it has more mods than my old 
2l/2l head combo, seems quite a bit slower. i got:

215/215/170/215

i don't think the scale is accurate, but the 215's are what i got on the 
"old" newly rebuilt engine, so i assume they are really in the 180-190 
range. cylinder #3 is barely, if at all, out of spec (>44 psi below other 
readings). when i crank it though, it doesn't rise as fast on the first 
crank as the others. sometimes it doesn't move till the second crank.

tried a wet compression test, but i think it was useless since the readings 
were above the gauge's scale (~300).

i'm thinking a stuck valve maybe, broken piston ring, or headgasket? the 
engine supposedly has 34k on it (mods below), and is super quiet/smooth for 
a scirocco 16v. no evidence of headgasket leak.  anyway to a) find out for 
sure short of pulling the head, and b) unstick the stuck valve, if that's 
what it is?

lastly, stupid question, but how much of a performance issue should these 
readings be? thanks,
