Light oil mist on front of cowl (M20J)

[jetdriven]

if you have a fresh <50 hour overhaul, let the shop that overhauled it deal with it. And paying for it too. You gave them 20k, there is no reason to dump another thousand into it for this.

Exactly what I told my mechanic. Check for torque, I will fly and test, and if the leak is still there I will call the overhauler.

I use Phillips XC and will probably start using Camgaurd this winter. Ed Kolin (who I believe was a chemist for Shell Oil) posts on another board I frequent. He's assured us that Phillips base stock is as good or better than anything else available.

 

I don't bother with the K&N as my Ram-Air is opened by the time I'm 300 ft AGL unless it's bug season.

We are going to XC 20w50 next change for the winter season, and W100 (not W100+) year round.  Dig around there is a lot of data on this, and it is the best thing for our Lycoming camshafts.

I switched to XC 20-50 and Camguard based on so many recommendations from web forums. Not sure if it really helps or not, but the FAA says it won't hurt, so I'll drink the Cool-Aid. I have a new interest in this thread now because my cowl now has an oil streak and misting too. At annual they changed the prop seal because I guess the had to grease it or something due to an AD I think. I really didn't want to mess with it because it wasn't leaking, but they said they had to. I may have been right. My experience with non aviation engines is that if a seal isn't leaking, don't disturb it if you can at all help it.

Hi. 

How can you stick a torque wrench in there?

I was renting PA28Rs while this conversation was going on

Seriously: it might be a good idea to retorque bolts as prevention. But how do you stick in a torque wrench in such tight spots???

don't be dramatic.  It's only been 9 years, 6 months.

Just wait, Mitch will be here... @MooneyMitch...

Of course... it may have been Jolie’s plane that we are discussing... (fuzzy memory of what the thread was saying above...)

But the technology is a 100 years old.
