A fluid exchange for the tranny + a pan drop and filter replacement FAST with a bottle of LUBEGUARD RED may extend the life many many thousands of miles.

The leaking fuel distributor is a 'must fix. The low compression on one cylinder is maningless without a leakdown test--goin gpast rings, intake or exhaust valve?

I have seen lots of 'leaking' valves reseat if you run a high does of TECHRON through the engine--often the cause seems to be clear varnish build up on the valve seat that starts spalling off when a new owner starts buying good fuel instead of cheapo stuff. Gentle driving with heavy 'clean-up' dosage of deposit may salvage the valve--if that's the problem. A single slightly low compression test is not conclusive. Fear-not.
