Fwd: Re: [Vwdiesel] Re-ringing a Rabbit --Oil pressure test bad

Got a oil pressure gauge and metric fitting kit tonight and plumbed it into 
my 1.6 na hydraulic Jetta. This is on a fresh re-ring I did and figured I 
clobbered when I went to start it for the first time and spun the cam gear 
making all kinds of bad sounds. I did do a compression test on it after I 
re timed it before I got it running and had from 320 to 380 on all four 
cylinders so was hopeful I hadn't bent any valves.  The car will start. I 
get lots of gray/white smoke especially if I rev it up. The oil light and 
buzzer come on as soon as I try to drive off.  I plumbed in the oil 
pressure gauge in the head sensor and even I can decipher the results.  It 
starts right up and builds pressure to about 70 psi max over about 20 
seconds.  It doesn't take long for it to start to warm up and loose o.p. If 
I rev it a little it builds up some but as soon as it tachs down again it 
loses all it built and then some. After running for 12 to 15 minutes the 
pressure is clear down to 10 psi. I noticed I am dripping oil somewhere 
also and looked carefully while it was running.  I can see it blowing oil 
bubbles around the exhaust flange. Not sure if that is from oil that landed 
there when I had the valve cover off or if it is coming from the exhaust. 
Sure looks like I really screwed it up. How can I be getting so much blow 
by already unless I did bend some valves or could I have broken some of the 
new rings when pistons met valves under starter power? I was hoping that 
the hydraulic lifters that could not have been pumped up that there may 
have been some forgiveness but now I wonder. I want to do the compression 
test again but am out of heat shields and re dimpled mine twice and they 
have some tiny cracks so need to get more.

thanks,

Bart
