I was updating the engine tuneup by clearing the OBD1 codes, EGR and low power...
The last tasks were plugs & wires....it seemed to have worked for only a few minutes to an hour @the most.

The idle seems fine and the accelerator peddle indicated a LOT more power...but an engine knock appeared...rather loud @that....

I checked the OBD1 codes again...Check cam sensor and/or knock sensors
Did this to both...even replaced them w/spares from the bone yard...but the engine knock is still present.

Since this engine doesn't have any mechanical way to adjust the timing/dwell from a distributor....I am seeking advise from other members who have had experiences w/engine knock....

I had given up on the engine knock being from the cam or knock sensor...for a nosier or loose valve lifters.... So I cleaned them w/commercial solutions...dropped the oil pan for inspection & cleaning...

Found some very fine metal shaving...but nothing unexpected for 245,000 miles...the lower end of the pistons looked clean & nothing loose...Nice & tight looking...

W/new oil filter, fluids & conditioners...the engine knock is about 1/2 the volume level but still there...the idle is still smooth but the accelerator power is fairly weak. OBD1 is still giving the cam & knock sensor "alarm"...!!! My Haynes repair manual has been somewhat helpful but it is fairly generic for specific "solutions"....

I would like to keep the old Sword alive but I don't want to "pour" hundreds of dollars into a deepening HOLE...

Any thoughts, experience or knowledge about engine knock solutions would be greatly appreciated...Thanks
