Engine (1990 350cid) picked up a miss, pulled plugs, #6 had water on it.
(initially thought it was #4 if anyone saw that post)
Started wondering if it was actually water since I didn't smell it or
anything... so pulled it again the next night... still soaked.
Put some Bars (stop leak) in it just hoping it would help until I could get
to it... pulled the plug three days later - dry.
Started wondering if I had pulled it too soon after driving so I pulled it
again two days after that, waiting a little while before pulling. Still dry.
Is it normal to see water on the plug when a head gasket is blown? I was
surprised, thought the water would evaporate quickly because of the heat.
I checked the compression, #6 (leaky one) was sitting at around 125. The two
others I checked for comparison were 140. So now I'm wondering if the
compression is low due to blown gasket or crack and the Bars just slowed the
leak down.... or if it could be low due to damage from the time water was
getting in the cylinder. Opinions?
What's normal compression for a 90 350 truck engine?
One more, does the distributor go through the intake on that engine?
