Hi all,
I'd like to get your input on the oil analysis I just had done on a 911 race engine from my 914/6. It shows elevated lead and copper, which I'm guessing could mean bearing wear. Does this mean the engine is just moving toward rebuild time, or does it mean "don't drive it anymore, rebuild now"?
A few details:
- I do use leaded gas.
- The engine is a short stroke 2.7 (93 x 66), is revved to 7500 with no overrevs, and has about 55 track hours on it.
The summary mentions "cautionary" about the lead but doesn't use as strong language about the copper. It also says that lead seems may be explainable from the leaded gas. I was expecting a little more time before a rebuild, but maybe time's up?
Thanks in advance for your opinions!
Scott
