Sorry to hear you had problems, Bill. I hear this is fairly common with
chrome bores - but a hone job sometimes lets you try again, and often
succeeds .....

There have been problems with the Cermichrome process, too, but it
seems like a better way to go ... The Nikasil cylinders on the 912
work GREAT !

Now that the 100 HP. 912-S is available, it might be a reasonable
choice .... We've certainly been a lot of places with the old 912,
lugging a lot of gear ! :-)

London's only about 90 miles away !! Small world !!! One of these
years, I'd like to get out to California - we've been to Florida often,
and the west coast of Canada, and I've flown a Rebel up to Kuujuaq, near
the Arctic, but have never had a chance to visit the south-west - maybe
one day !!

Hope honing the cylinders will do the trick !

Bill & Bob
In regards to your comments and problems with oil consumption. I have used
chrome cyls. on

L-0360 engs. and overhauled several engs. using re-chromed or just honed and
etched barrels.

Not to be confused with "cermichrome" cyls. I have found the best way to
break in new cyls.

was to run the eng. hard, that is, high man. press. and high rpm from the
very start. I

have even gone so far as to start the eng at the end of the runway and take
off

immeadiately. Of course a short run after eng. installation to check for oil
leaks is

nessary but at all costs avoid ideling or low power settings in the air. I
try to run a new

eng. for 2-3 hrs. on the first flight.

I use non dispersant mineral oil for about the first 50 hrs. changing at 10
and 25 hr.

intervals. I use 1-2 qts. the first 10 hrs. After the eng. is "broken in"
(100 hrs.) I will

use about 1 qt every 10-15 hrs. I don't think chrome cyls. will ever be as
oil consumption

free as steel cyls. but I sure do think they last a lot longer. The main
thing about new

chrome cyls. is NOT TO BABY THEM!!

With this method I have had engs. go to 1700 hrs. with still good chrome in
the barrels and

good compression.
Hope this is of some help to you

Alex Russell

Thanks for the tips, Alex ! I'm sure they'll help several builders,
when it's flying time !! :-)

For those interested I found out recently that Lycoming produce a video on
how to look

after new or overhauled engines in the run in period and to obtain the
maximum life out of

them. I have a copy. It has the same message for running in mentioned by

AzAlexR@aol.com
That is don't baby the engine for a start. I can provide details if anyone
is interested
