Thanks Bruce,
That will be number one on my list today, after work.
I am going to pull the finger screens at the back ( bottom) of the rear case
while I am at it.

I need to get my confidence back on this engine.

We took off the oil pressure line, between the engine and the fire wall.
we did not , crack / bleed the line, but we ran the engine with the line diiscoonected,
and no oil came out.

Yes the tach is still working, as is the alternator, and mags.

I took off from my home airport the other day, when I was approx 8 miles away I see my oil pressure is now at zero, :cry: ....I turn around and start back , oil temp is normal, I reduce power to 2300 rpm, CHT and EGT are all normal on all 6 cylinders. I make it back and land ok. :D Oil temp stayed c...

Hi Bruce,

Great, That is just the lead I was seeking, Thank-You !!

Hi George, Well the bottom inside of the sump looks smooth, and the small little areas where the paint has flaked off looks smooth and no signs of corrision ? The AME, at the hangar here said the same,...... my current sump has and area where it was repaired, and the repair is very appearent, also a...

I need to change the sump, on my O-300D, as the threads in the forward drain plug are cracked.( ?? ) I have a replacement 5 hole sump :) , (as removed ) it is in nice shape as there are NO signs of corrision, or any previous repairs to the sump. The sump is painted light blue, inside and out ?????? ...

My take was,... It got carb ice the day before with temp about -5c , and it never cleared as the carb heat was not working, Then the next morning it was -16c , and the ice that was allready in the carb, got nice and hard over night at -16c. I pre-heated, ( oil sump pad and 100 watt light bulb ) then...

Hi George,
Have you heard of the butterfly valve breaking like mine did ? Along the shaft ?
It looked like the valve was only welded on each outside edge .? Is that correct?

Is that all that holds the valve on to the shaft ??

Hi Tim, Yes possibility that was not the best choice in hind sight. I thought I could get airborne and stay a couple hundred feet, but she just did not have the power ( O-300 ) . The snow was just too deep. I am home now and, the problem was the carb heat divirter valve broke in half along the shaft...

Good point, Fred, I will check, it first thing this morning, I did not think of that,...... -16c this morning.
It will be a bit of a chore to get it out if that is what it is, but I will be VERY Happy , if I can find that it is
The problem.

Thanks. John

Thanks , I would like to get back home, on Sunday for work. I am not too certain how happy I would be in Yuma, not too many real forest, For camping, and good fishing lakes. I have been to Arizona , many times, in winter, and summer, but I still perfer the seasons. Not too much ski flying in Arizona?

I am up on a lake in semi northern Canada, With my 170b on wheel skis approx 139 nm NE of Toronto. Minus 13c tonight. This is a remote area, no telephone, no electrical. The snow is 10+ inches deep at my place.so I had to Taxi approx 2 nm. To my friends place ( who has satellite Internet ) during th...

Left rear plug, is #2 cylinder, my #2 always runs the hottest, (I have 6 CHT + 6 EGT ) and #2 has always been the
hotest, I have new baffels, and re-checked every thing, I guess someone has to be the hottest.

Hi Greg, I have a 52 170B as well. In my option, the 3 best mods are, 1) pull handles for the tail, 2)180 gear legs, and Cleveland double puck brakes ( if you run 800 tires, ) 3) P Ponk gear box upgrade. (Once we started to do my upgrade we found that the existing Cessna gear box extrusions were bad...

I believe, around 1965 , they put the extra rear wind in the C 180 as well as in the C 185.
