Dear Group,
Took my '54 3100 in for a compression and leak
down test today, but I'm unsure what it all
means. Here are the fugures they gave me.
Comprssion/PSI Leak Down % Hot 8K
#1 130 40% rings
#2 125 50% rings
#3 105 50% valves
#4 85 70% equally
#5 120 15% valves
#6 125 20% equally
Of course, they would have liked to have kept my
truck. There is no smoke coming from the tailpipe
and I'm no using any oil that I can tell.
Sometimes, when I start her, I get a funky, sweet
smell that goes away after a few minutes. Other
than that, I like driving my old truck.
What do all these figures mean?
