Larry,
Thank you for your detailed replies. They are truly helpful. My engine does create small "puddles" of oil, but usually only after a long and high speed drive (>20 miles at >65 mph). I have noticed oil on my engine block on the side with the turbocharger. I have had the oil hoses for the turbo replaced, but the leaks continue. Do you know where these engines like to leak?
