11-7-2007 (I recognize that 10W40 is not on the list. I was just trying to
put a thicker oil in, hoping oil loss would lesson. I am back on 10W30 for
the winter)
I checked engine compression today:
All 6 cylinders show 220-230 on the guage. However, with 3 cyclinders, it
took about 5 strokes to get the needle that high. Generally, the first
stroke got about 85, the next got to about 130, etc. Two cylinders seemed to
go to 150 with the first stroke. I will check this again if this is
significant.
The plugs are the 3-electrode type and look good although there is some
carbon on the ceramic between the 3 electrodes.
Number one plug shows black in the threads. All of the others had clean
threads. The deck under the engine cover is clean and dry. The underside
of the engine is clean and dry.
The tailpipe is somewhat blackened but not much different than our 1997
straight six (S-80) (really a 960) with same mileage but no oil consumption
at all.
Thanks to the experts on advice of what, if anything, to do to reduce or
control oil consumption.
