I am getting ready to install a Howell fuel injection on my 86cj7 258. Before I do this I need to figure out if my engine is OK. It likes to blow blue smoke at stop lights, sometime a whole bunch sometimes a little. The engine is supposed to have only 10K miles on it. The number 1,2,3,6 plugs are a tan whiteish color and the 4 and 5 plugs are black. I did a compression test
DRY = 1-185 2-190 3-185 4-175 5-175 6-180
WET = 1-195 2-200 3-195 4-195 5-185 6-195
Does this tell me anything? What do I do next?
