Well done.
Where was the oil falling to? I have a very small oil leak which I've failed to trace. What did you use to reseal both locations?
Cheers

Maintenance... pulled off upper/lower cowling for inspection on recent five year rubber change; got to the bottom of remaining oil weeping by resealing #1/3 valve covers and two M6 oil pump retaining bolts... fitted a set of NGK iridium spark plugs and a 50hr oil/filter change today ahead of fitting wide band O2 sensor to monitor fuel mixtures...

Finished current service session and carried out post quality assurance checks this morning on 181's 912... "Amazing" 😊 is the word; engine runs on the iridium spark plugs like its fuel injected now, unbelievably smooth and has got to be the smoothest 912 i've experienced so far; mag drop check is identical at 50rpm; startup is instant with zero vibration through entire rpm range right down to 1100rpm. Wouldn't surprise me if remaining final O2 sensor mixture tuning session requires no further adjustment. Can't wait to give it a fly tomorrow morning!
Break Break:
James the oil weeping was identified at two of the M6 oil pump bolts; so They were removed individually and permatex grey applied to the bolt shanks and refitted and re-torqued. Both valve covers on the right bank were also weeping, so removed, checked for any screw driver damage to parting lines, degreased both cover and o'rings with shellite then refitted with a light smear of permatex grey at the o'rings then refitted M6 bolts and re-torqued. (Note that whenever using sealants, especially silicon, on oil-side engine components to never apply excessive amounts as dags have been known to break off and block fine oil galleries and cause premature component/bearing failure).

Thanks very much for that information Area51.
Next time I get a chance I'll check those locations on my engine.

Chasing oil leaks can be a challenge. Some used to get excited about achieving dry british motors but then the rest of the vehicle would rust 🤷🏼♂️.
Best way to go about it is start with the worst leak first, wipe it all down as best you can with old cotton t'shirt and then spot clean with either brake clean or carbi clean; if its real filthy carbi clean will rip through grime the best... Get the whole engine and surrounding mounting frame and cowling totally degreased and clean before putting your lower cowling back on (do not use caustic degreasers on alloy components; it eats alloy and destroys alternator windings) ... (use compressed air to thoroughly blow off any remaining water if hosing down degreaser - use acetone last to wipe down cold exhaust headers and muffler) do an extended ramp run at 3000rpm for at least 5-10 minutes so long as your temperatures stay green. First few minutes will produce a bit of weird smell as hot exhaust surfaces burn off.
Pull the lower cowling and start looking from the top front of the engine around gearbox and fuel pump first then top lower at the oil cooler lines, oil pressure sender, oil pump and filter, valve covers, pushrod tubes, crankcase plugs and unions, rear camshaft gear cover... If you are lucky you will be able to identify more than one leak if there is more than one source) note - don't overtighten hose clamps on oil lines, some style clamps will cut through hoses if overtightened. Sometimes oil hose will harden with age and just keep leaking; replace the hose.
5-10 minutes running is enough to show up a leak; 30-60 minutes flight time is enough to show up weeping. A leaking/weeping bolt will be wet on its shank when removed; it its dry then that's not the source of your leak.
The lower cowling vent around the exhaust provides enough room to shine a torch up under the crankcase for a quick visual. A mirror on a stick is useful as well with the top cowling removed.
If unions still leak after tightening to correct torque settings then sealing washers should be replaced. Copper washers can be annealed and reused; Wurth Dowdy washers are the best for unions and plugs and reusable.
There's no excuse for a rotax engine to leak, however a leaking volkswagon motor is fashionably acceptable.

FWIW
To add to Bud's advice/observation, I have found the biggest bang for the buck in landing the mono (which by definition is always in full stall) was my addition of the CYA100 vane-driven AOA. It pointed out very quickly that my flair speeds were generally too high. In addition I was amazed how noticeably higher the indicated stall speed was in my classic when a passenger is added. No wonder folks can get discouraged with the mono by relying solely on indicated airspeeds if flying different weights etc.
Cheers,
PeteZ

To Area 51:
Gaining confidence in the mono is done in steps, and if done with the right attitude, precision and perseverance, ends up being a joy.
Believe me when we say we are all impressed at your skill and control as the mono is different. Asphalt is no different in technique from smooth grass if you just keep on your toes and don't get distracted or lazy then try to stick it on.
I agree with Pete, smooth asphalt is nicer than a rough grass pasture.
Well done. Keep the stick back.

Hello,
We happen to need today a sunset flight.
Departed from home. My grass strip is just 200 m (650 ft) long (a landing strip is 300 m long [almost 1000 ft], but only 6 m [20 ft] wide).
[img]cid:part1.lIKRYW63.JmAfzy0I(at)rwm.fi[/img]
The weather was again so perfect, so smooth.
About the weather, we have been here so far so lucky.
[img]cid:part2.0NsGZg0q.uk9gn8nC(at)rwm.fi[/img]
We flew into sunset, to land into a remote hotell to get some late evening food.
[img]cid:part3.W57TaEGl.lgm3iI8J(at)rwm.fi[/img]
And noticed again how beautiful our country is.
So much free unpollutioned space, forests and clean drinkable lakes.

When flying back, we did it over Tampere.
Tampere is the largest inland water city in the Scandinavia, and can you imagine
- there are well over 200.000 inhabitants!
[img]cid:part6.Yj3idna0.2dCYwYyj(at)rwm.fi[/img]
And, because I have no lights beside my strips, we landed to the EFTP Tampere.
[img]cid:part7.xGO04pCD.5Y0WJmyC(at)rwm.fi[/img]
And put She to her very personal cave.
Still so warm, because of the climate change, it´s a bit like in a jungle here.

Chris,
I have taken a lot of instruction and training in my life, but frankly, I always had to learn it my way. If somebodies idea didn't work, ask and go try it.
Personally, I hold the stick back until about 35 and the engine is good then relax my death grip holding the stick back and just let it fly off. Moving the stick forward enough to maintain the pitch attitude.
It works for me. Once you are comfortable in the aircraft, you relax a bit and feel the aircraft.
Best Regards,
Bud
