I have a question about an oil leak that I found on my airplane last week. The plane has 700 hours on a 470. I put my first quart in it after 11 hours of flight. I added this quart a week ago. I’m not a pilot yet but I’m able to taxi the plane at my airport. So I just taxed it a couple places At the airport and did not fly it and I noticed I had oil splotches on both sides of the fork on front. Had me concerned I stop by A mechanic shop. After taking the decal and running it they claim it’s valve guides which he’s got me stumped. The oil seems to be dripping out of the air induction system breather. The plane was five in North Carolina last August. The original oil is in it which is 15- 50 Aero Shell. I’m changing that to 100L At my annual in August. In fact I’m going to hold off until that annual to really do a through check Of the motor. I’ve been flying it consistently the last 5 weeks and i’m ready to solo. Been working in the plane pretty hard take offs landings in the 90s so we’ve been watching the heat gauge but never seen it overheat. But this oil leak is got me somewhat worried. The mechanic claimed he needed the pull some jugs to figure out where it’s coming from he young and Anxious. I said let me think about it because that is a big move. It actually made them mad at me and I’m not gonna take my plane back there again. Also they claimed it takes 11 hours per Jug to investigate at $100 a hour l. I Have the right to think about it. It’s nowhere around the jugs that it’s leaking. The valve covers are dry. Some oil is back toward the accessory box and may be a little bit coming from the Air pump. With the Cowl off They started it and ran it And they said the oil was dripping into the induction system and out the air breather which may be an indication of s valve guide. What do you think? The mechanic said just fly it and watch the oil level. The last time we put flew there was no leakage that I noticed after 1 1/2. I haven’t flown it since I finally saw this leaking during my taxi since I’m not a pilot. My instructor will be back next week and will go up one hour landed and investigate to see what’s going on. Hopefully not a whole lot. I guess all I did today was taxi it but not take it to flight. Maybe it was a cumulated oil that finally showed up because I did not take it to fly. Your opinion since I know you’ve worked on a lot of these. The engine have 700 hours on a rebuild that took place 8-10 year. s ago. It’s a 1956 Cessna 182
