I have a general question regarding the administering of a compression
test. The instructions I got mentioned a full open throttle when performing
the test. My question is what are the ramification of performing the test
with throttle at idle position? My readings were all in the 150psi range
and took approx. 5sec or cranks to reach this pressure? Are the readings
valid, or should I redo the test with the throttle wide open.
As an update to the 4000S no start condition, it appears I have slipped a
tooth on the timing belt. My camshaft sprocket and distributor cap both
line up with there marks, but the flywheel is off. The belt also appeared
to have more slack than usual, so I have doubts the tension was adjusted
properly. Is it recommended to change the tensioner bearing? when changing
the timing belt?? Oh well, post an update later.
TIA for any responses...
