Re: compression range 900 1992

Those readings are very good.

The low cylider is well within 10% of the others so it is not anywhere close enough to a bad reading to suspect that it is a compression /blowby leakage situation.

Is the vacuum port and hard vac line open?

The black plastic fitting the vac hose plugs onto down on back of intake plenum could be plugged.

If the engine is sludged up inside from pooe maintenance, it couls still have a stuck second ring and have good compression readings.
