Subject: RE: Oil temp still too high
As I think it is clear, we =93 that is Aerometal, my partner in
Hungary =93 overhauled Jon=99s engine. As I think people
know, we have a proper dynamometer, and every engine on which we work
undergoes a formal test programme in which it is run for a minimum of
three hours and every parameter recorded, and provided to the customer.
Certainly, everything was absolutely normal in terms of oil temperature
and pressure. As I believe Jon will confirm, we have been doing
everything we can to help him =93 since he clearly has a problem,
and my view is that those temperatures are definitely too high. But of
course we are inevitably in the dark since we have no idea of what
modifications were done to the Nanchang oil system to accommodate the M
14 engine. It would seem from what Jon has told us, everything is as it
should be, but of course there is always potential if one is deviating
from original, of something being strange.
In particular I was concerned about the oil cooler =93 I'd
emphasise that we know very little about the Chinese oil cooler, but I
do know that in the Russian cooler, which originally were fitted with a
thermostatic valve, but this was very prone to sticking, and has been
removed from virtually all aircraft. I understand that the Chinese oil
cooler has a bypass valve operating on pressure, not temperature. But
given that Jon has an engine delivering a lot more power than 285 hp,
and so that much more heat, I suggested that he should remove all bypass
aspects of the cooler, ensuring that all oil would have to go through
the cooler.
But we are obviously in touch with him and will do what we can to sort
out the issues.

Jon;
The temperature numbers you listed are pretty much what one should
expect for the initial stages of break-in. The oil pressure, on the
other hand, is not. Can you tell me the total time on the cylinders and
whether they installed new cylinder barrels. If indeed the overhaul
facility is a reputable organization you should have a multi page
overhaul report detailing all new components and details of all the
inspection, repair and restoration procedures complied with.
Best;
Walt

Richard Goode / Aerometal. Still scratching our collective head. They
sent the smaller suction jets which helped the CHT. Richard thinks that
since the engine is making much more power than a Chinese engine perhaps
the Chinese oil cooler is struggling to get rid of the extra heat.

My oil temperature continues to be too high during engine break-in
despite attempts to mitigate it.
Engine: zero-time overhaul M-14P, standard compression Barrett pistons,
auto harness, no other engine mods (on a stock CJ-6A)
Does have Criag's oil filter kit. Oil cooler recently overhauled by
Pacific Coast.
Previously I had very high oil temps and high CHTs so I went from a
1.4mm suction jet to a 1.3mm suction jet and switched from Aeroshell 100
straight mineral to Aeroshell 120 straight mineral (which is quite hard
to find!)
Ambient air temperature 36C/97F. Field elevation 500 MSL.
Engine start showed oil pressure at 5 bar with inlet temp 35C.
Take-off at 2900 RPM and full throttle resulted in CHTs climbing to 210C
and oil inlet temp to 65C, outlet climbing to 85C, oil pressure 5 bar.
Settled in a little lower than pattern altitude due to high CHT then CHT
came back to 160-170C at 650-700mm MAP. Oil pressure 4 bar at 2400 rpm.
Oil temp continued to climb to 75C inlet temp, 100-110C outlet temp,
while CHT 160C, oil pressure 4 bar at 2400 rpm.
Two circuits in the pattern at ~650mm MAP, oil inlet temp stabilizes at
75-80C, outlet 110C, CHT 160C, oil pressure a little below 4 bar at 2400
rpm.
Landed, CHT now dropping, oil inlet still 75C outlet 100C, approximately
1000 rpm, oil pressure now below 1 bar.
Ideas?

We installed the flow restrictors on all inputs to the gear actuators.
What a difference in the gear cycle time and no banging to the stops.

ALL,
As many of you know, for the last 2 years I have been fighting Multiple
Myeloma, which is a blood cancer, treatable but not curable. Your support
and prayers in the past years have been greatly appreciated. The cancer
seems to be holding its own so it looks to be a long road ahead. Because
of this, after over 30 years of supporting Yaks and CJ's Kathleen and I
have decided it's time to call it quits and spend what time is left to us
enjoying each other and fishing with the grandkids. *Please note that our
last shipping day will be July 1st.*
If perhaps you know of someone who is interested in owning the only
stocking CJ6 parts supplier in the US, please send them our way.
Best to you all

Thank you so very much for all of the support with parts and education on
the CJ 6. Knowing you two has made transitioning into this aircraft as
easy as possible. When I was talking to Dennis about CJs and Yaks for a
year or so before I bought a CJ, I asked about spare parts. Dennis
immediately said dont worry about that, you will get to know Doug
Sapp.....And so it began.
Thank you again
