Engine was cold on both tests.  I was told that I should try the test after
driving the car for a while,  and heating the engine to running temp.  If
the PSI in #3 makes a large jump, then it might actually be a botched valve
job.  At least I have hope.

I'll try that tonight.

Was the engine hot on either test ?
If you checked it cold and then hot on the other your going to get a spread.

So last night I had two options for things to do.  1.  Do my laundry as I
had no more work clothes, or 2. Check my compression for no apparent reason.

Of course I check the compression.  And now the results.

Cyl 1:  130
Cyl 2:  130
Cyl 3:  110
Cyl 4:  130

So now I'm concerned about #3.  About 500 miles ago,  they were all around
125 to 130.  Now the 125 ones are @ 130 and a 130 cyl is at 110.  I put in
5cc's of 20W50 and redid the test on #3 with no change.  5 more cc's (10
total) and the PSI jumped to 125 from 110.  During that 500 miles,  I've
changed from SAE 40 to 20W50.  Could that have contribute towards the
difference?

Could I have botched the valve adjustment,  or is this simply a sign of worn
rings?  If the latter,  is there anything I could do (other than not drive
the car) that will prolong the problem.  Probably not.....

PS:  I wound up doing the laundry too.....  Not as much fun, that's for
sure.
