Cap't. Page,
Compression test not likely to be of any help when trying to diagnose a
bad rod.
Query???
Is the "knock" constant with a regular rythm? Does it also increase in
speed as rpms increase but not change in tone?
If so, odds are very high a rod is going.
Start the car, run at idle only. Use a long socket extension or engine
stethescope and "listen" at the base of the block just above the oil
pan, directly below each spark plug.
If the knocking becomes more pronouced at one spot, you have located
the culprit.
I would suggest you NOT give the engine much in the way of RPMs. If a
rod is indeed bad, high rpms can throw a rod through the block if it
comes apart.
Sounds like rings, rod bearings and mains are in order.
An engine that is allowed to sit idle for long periods can develope
seized rings and corroded valves and guides from lack of lubrication.
Is it possible that the car sat for nine months because of a bad rod?
Hate to sound like the eternal pessimist, but why take chances. Blocks
are very costly.
