It appears that the old Toyota 18RC engines seem to ping badly
when they get old does anyone have any specialized information
on the problem? I have tried using 91 octange gas, *and* severely
retarding the timing. This still did not work.
The car does have 140K miles on it though.

*** REPLACE THIS LINE WITH YOUR MESSAGE ***
Be very careful in how far you retard your timing. You can easily cause
your exhaust valves to burn. As I picture it, retarding the spark causes
the gas to burn later in the cycle. If this retarding is too far, the
gas will still be burning when the exhaust value opens up. The hot, burning
gas being forced out of the exhaust port at high pressure, etc. will get
the value too hot--and presto--a repair bill.
But this doesn't help on your pinging problem. Good luck on that.
