Hi everyone,
I have had 2 UOA done and both showed high (30+) levels of silicon in the oil suggesting unfiltered air is entering the engine.
The car idles poorly at times, so initially I thought a vacuum leak must be causing both the idle issues and the silicon content, however a smoke test did not reveal any leaks.
Any suggestions of what I can do to test where unfiltered air is coming in from?
This is for a 2003 Mitsubishi Diamante.
