Any idea if this can be done on a Lycoming IO-320-B1A?
Of course. Vividia VA-400. Kudos to Photofly.
Where would you put the boroscope? How would you get it close to the cam so you can inspect it?

Yes, I understand one cylinder wouldn't tell you the whole story, but I would definitely feel better if I managed to inspect at least part of the camshaft vs not inspecting it at all. And I know you understand the value of feelings ;-)

Oh dear. I can only imagine how Chuck might answer that :^)

Ok, camshaft is at the top of a Lycoming. So is the oil filler tube.

Colon-el:

Are you saying the only two oil change is spring and fall, regardless of time flown?

I’m doing 50hrs for my 180, and 30 for the 182 (wait for it...) at the request of Blackstone, to narrow down particle levels.
I fly about 200+/year on my 180, and the 182 is shaping up to do that as well, since I have 3 other dudes flying it. It’s a little slutty, if you ask me.

BTW, the 182’s new panel:

What is the effect of Camguard in a car engine?
Anyone tried it?

I think I said for an infrequently-flown aircraft (eg 50 hrs/yr (or less)) ...

Nice panel!

See what having an advanced degree gets you? Failed reading comprehension!

I am surrounded by post-graduate weenies :^)

Photofly at last count has FOUR degrees - I can't count that high -
and Francis holds a PhD.

Now I know how Howard Wolowitz feels! And you know how important feelings are ...

ASL sells Camguard for all engines.

Internal corrosion has never been a problem for me, with car engines. Often
when you tear down a car engine, you will find horrible deposits and sludge,
but that's generally not the major cause of failure.

I bought a Honda Civic new in 2001 and hit 7000 RPM leaving the dealer
parking lot. I broke that engine in very gently, as you can tell. The weak link
of that engine was the interface between the block and the head. You could
re-torque it, you could change the head gasket, you could machine the warped
head, yada yada yada. Pissing into the wind. It was going to fuck up and there
was nothing you could do.

What I did was change the engine with a new (to me) D17 from the junkyard
every third of a million kilometres. Never changed the oil or any fluids, just
topped them up. I think I ran that Honda out to three quarters of a million
kilometers? At which point, structural rust had taken it's toll.

Now I live someplace with no salt, so the cars don't rust. You see people
driving around in cars from the 1950's which is pretty neat. The sun destroys
the paint on the top of the car, though. Clearcoat peels like a stripper on Friday
night on payday on all the old cars, with that sun beating down, day after day.

Good recepie for moisture condensation in the engine

Wouldn't hurt. The $64 question is, does Camguard add anything that
isn't already in the additive package of the SAE oil he is running?

See, if you had a PhD like this guy, you might know the answer:
