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

[Bart Wineland]

I need to clean the engine off again to see where the oil is leaking from. 
When I could see the oil bubbling around the exhaust flange donut while it 
is running my first thought was it was from oil getting by the rings into 
the exhaust and thought that may explain the heavy white/gray smoke and low 
oil pressure also. But that oil could have come from when I had the valve 
cover off?? Wouldn't blow by cause a loss in low oil pressure?  It does 
tango alright. From a high of 70 psi with a cold engine (about 40 degrees 
outside) to under 10 psi after it warms up for 12 minutes. I did use old 
cut off head bolts with slots filed in them (per archives) to keep the head 
gasket aligned. It is a hydraulic head with the extra oil port so the 
gasket can't go on upside down. Torqued it according to Bentley in sequence 
I think 30# first pass, 40# second, then with just a breaker bar for the 
final pass, although Bentley calls for an additional 1/2 rev. on each bolt 
I could not get that. Maybe 1/4 rev. I was sure the headbolts were going to 
twist off. I forgot to mention that the oil pump was replaced last fall 
before all this started also, so it only has 9 or 10k miles on it and oil 
pressure was not a problem before I pulled the engine and fixed everything 
:)   Pressure at the pump sensor? You mean the sensor at the filter?
"Don't you give up."  You guys make that pretty hard.

Thanks,
Bart
