I cannot offer any explanation other than the brochures were intended to "dress up" the advertisement. Cessna did the same thing to many of their own brochures. (One of the amusing brochures I have depict an incredibly spacious interior .... They used "little people" to represent the aircraft in brochures to make the aircraft look better than reality.)

I'll try to post one or two of them.

If you are going to do a rebuild on a O-300 make sure you can get all the parts required . It’s my belief that crankshalfs [8 hole flanged] and cam shalfs are hard to get new. We were given some new pistons from continental for the overhaul as originals were not obtainable at that time. We had to machine some relief cutouts in the pistons for spark plug clearance . Also the pistons were 10thou oversized also, as I remember painting the cylinders barrels flange were painted green. Cylinders were ported and polished and engine was balanced . Wow, did that engine purr. We had one oil leak that I never had the chance to fix. The oil used to weep out of the RH mag lower attach bolt thread as it went into the case. No cracking in the case but leaked in that area.

Ah the .010 Oversize pistons rears it head again.

Many many times these get STD size piston rings installed. You have about 90 hours till Head has to be removed.

Rings will be worn elliptical shape.

Lycoming is now adv engine parts w diamond treatment - there is a possibly of 2500 hrs and still new original honing marks. Spl 60 year old technology.


As to the Color scheme I admire your work. Beautiful.

Some how 25 years a go some one sold me a rattle can of "Continental Gold" very special.

Here is a photo of a O-300 in an aviation museum in England produced under license by Rolls-Royce, notice black rocker covers. Is it possible some of these were sold or used in the U.S.

I can’t quite read the name on those covers. Would be cool to have covers embossed with “Rolls Royce” on them!

In spite of photos of new C-145 engines with silver-colored rocker covers in Air Facts magazine and all the C-170 owners manuals, I think George may be correct in that production engines had black covers and silver was used to dress up the engine for advertising. We’ve found similar discrepancies with the black vs. Lima Tan flap handle. I think I’ll have cylinders 1-3-5 black and 2-4-6 silver. :) Rusty's covers are black, Dillon's are silver. What color are Jacobson's? Or the '48 barn find with 490 hrs TT, N4039V? It’s amazing to me that with one of the most produced classic - not antique- aircraft details like this are so hard to verify. I guess Aunt Flo just wasn’t interested in taking pictures with her Brownie of Uncle Hank’s new C-170 with the cowling off.

Not George.... I was only regurgitating what the "old Masters" who probably knew... taught me. :wink:

While the subject of RR involvement with Continental and rocker covers has been raised . Back in the 1960,s we had a manufacturer here in Australia produce a 2 seater aircraft called the Victor Airtourer. It had a engine originally O-200 [ looked exactly like a continental engine] but with RR badges on the cowl and rocker covers embossed with RR. Then it had a upgrade to RR O-240 engine. All engines painted all gloss black. But then we had some European aircraft arrive in Australia with O-300 fitted but with RR badges fitted. I can recall my dad saying they must be good engines as RR had made them but I couldn’t understand that if RR made them why did they make so much noise . [ I was only 10 years old] .
However just to muddy the waters even further about 8 years ago we bought a fork lift at a auction for the hangar. It was old [built around 1960 ] and blew heaps of smoke when running. It had a 4 cylinder petrol continental motor in it. [made in the USA tag ] . So we were going to overhaul the motor . No parts were available from continental motors . After many photos and emails to continental ,they suggested that we contact RR in England . EH???? You serious ?? RR came back to us yes the parts were available as the engine also was fitted to a RR car [silver dawn ] in about 1956. The parts were dirt cheap also. We paid at 1956 prices no increase for inflation.

Hi-Cruise Aeromatic propeller control or, according to Bruce, a Globe autopilot control.
