I have a strange situation going on which I see a streak of oil on top of the cowl about 3-4 inches from the center line on the co-pilot side that starts from the cowl?s very front to the back of it. This is the second time that I have seen this as the first time I thought it was residue of water from washing the canopy. I cleaned it just to see if it comes back, and sure enough it did after 3-4 hours of flying. It is of a very little amount, my guess about a couple of drops as you only see traces of it.
It does not seem to come from the spinner as I looked very closely and did not see any sign of any oil, also it would be strange that it has been exactly on the same spot. I took the top cowl off and could not find any trace or sign of oil on the inside of top cowl or baffle material that could have sipped thru. My guess is that it is coming from the bottom of the engine, perhaps due to excess pressure, and from the gap that exist between the cowl and spinner but again I did not find any trace of oil on the lip of the cowl.
So, I have a few questions for the gurus:
- Has anyone seen such thing or have any idea where this could be coming from?
- What is the best way to detect source of oil leak
- If I was going to wash and clean the engine what is the best method? I was thinking of covering the megs, battery, starter and alternator. Any other precautions that I need to be aware of?
Thanks in advance
