My 2000 ISB 260 HP engine has had two oil analyses from Blackstone, this year and last, with elevated iron and aluminum levels.
This year I had:
Aluminum 32
Iron 65
I have 1,000 miles and one year on this oil change. The analysis during the previous year showed the aluminum and iron levels starting to rise. Previous to that all was normal. I show no trace of coolant in the oil and silicon is normal indicating the air filter is performing well, I think.
I am looking for recommendations of where to look for the problem and what to do. I prefer to take some action instead of waiting for it to get worse. I have had opinions that the problem is piston and cylinder wear, bad injector, or main bearing wear. One key is to explain the aluminum levels. Would a main crankshaft bearing contribute to the aluminum level? Any help would be appreciated.
