I went and looked at it today and its decent enough looking but I found some corrosion at the bottom of the left wing strut and oil on the back header tube on the left side of the engine.pa22 corrosion.jpgpa22 oil leak.jpg

my two cents for what it is worth

on the second picture( engine)- I would look at the cylinder drain back tube- it looks like it has a leak- it appears wet with oil on the sump to crankcase usually a tell all with a leaky drain back tube.
also if you look at the front spark plug and compare it to the rear one- think you may have an exhaust leak on the front exhaust stack
perhaps a further look see is warranted

I concur.
Both are common problems on Lycoming engines.
Intake gaskets are also a weak point.

The pushrod shroud tubes will also leak from above and leak down like shown in the picture.

Really appreciate the comments. From the responses so far it doesn't sound like its a major problem. I'm no stranger to engines and their individual quirks but this is a whole new learning curve for me. Should I be concerned about the rust at the bottom of the strut ? The owner says he did not find any corrosion internally and the logs indicate a recover back in 89.

That is an odd spot for rust. I think I would investigate further, maybe pull the floorboard adjacent to that area.

I thought my plane had corosion in the same place. Turned out it was residue/trash/glue??? from a fuel selector leak in the past, no corrosion. Might be something similar.
