my lead is at 65 ppm...
I add mine to the other requests for more information.
However, if this engine is like many others, the high lead without high tin might point me towards rod bearing(s).
A quick review doesn't indicate any particular problem with Honda V-6 engines, so I'm assuming this car has some miles on it - the rod bearings usually fail before the main bearings.
Otherwise, I'd expect an incident in the recent past - loss of oil pressure, coolant and overheating, someone put leaded gasoline in it, a major engine repair was made - that might put this into perspective.
If no incident preceded this unusual reading, and you've got 100k or more on it, an assessment of the engine - borescope/fiberscope and compression/leakdown test among other things - ought to precede taking down the oil pan for an examination.
If the engine is worn, replacing the rod bearings or other major engine work may not be prudent.
Why not spend a few bucks and let Terry Dyson look into it?
