First the background:
1990 4.0 w/ 228,000 miles
Blew the freeze plugs out about 3 months ago. Replaced the plugs and ran it about 3 months. It blew them out again and now it will not start. It turns over fine. No antifreeze in the oil at all
It is running extremely rich. (blowing black smoke and you can smell the fuel out the tailpipe)
I was suspecting a blown head gasket so I ran a compression check.
Here are the numbers.
#1 150
#2 130
#3 140
#4 130
#5 135
#6 132
These numbers surprised me for a engine with this many miles, but it still will not start.
What else am I missing? I have checked spark and I have good fire on all cylinders.
