[TR] Compression check: what does this mean?

[Ed Oot]

59 TR3A

 

Symptoms:

Suddenly started to run poorly at low RPM under load.

Blowing smoke from both the vent tube and exhaust

 

Procedure:

Reset valve clearance to 11 thousandths across the board

Static set the timing to 4 degrees BTDC

Warmed the engine 

Pulled all plugs

Dry checked and then wet checked with the following results:

 

1)      D 152     W 170

2)      D 152     W 165

3)      D 120     W 140

4)      D 155     W 180

 

Do I have a broken ring on #3?  Also noted that when I pulled the plugs
after warm up that the #3 was wet. Not sure best approach.  I'm quessing the
engine was last rebuilt around 1990, and has maybe as much as 50K miles.

 

Thanks in advance for advice
