My 2000 SPI has started smoking on start-up. After it warms up it goes away. I am going to check the compression on the cylinders. Does anyone know what what numbers = good compression?

Thanks

Alan

Are you sure its not water condensation? What color is the smoke? Does it smell like burning? Could be unburned fuel or coolant. If its really cold out I think engines can run rich on startup. Check your coolant level.

Ford's spec is that the lowest cylinder is within 75% of the highest cylinder. I know the SPI engines had a problem with sticking exhaust valves, so much so that ford redesigned the cylinder head to combat the problem.

I actually did a valve job about 1 1/2 months ago. New valve guide seals and all.
The smoke is blueish and smells like burning oil
