Have you checked the bypass relief valve to see if it is
correctly installed after the cooler was cleaned ?

Engine: zero-time overhaul M-14P, standard compression Barrett pistons, aut

Does have Criag's oil filter kit. Oil cooler recently overhauled by Pacifi
c Coast.
Previously I had very high oil temps and high CHTs so I went from a 1.4mm s
uction 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 an
d 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 ca
me 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 10
00 rpm, oil pressure now below 1 bar.
Ideas?

I fly and M14P powered CJ. It has a Chinese oil cooler. I replaced mine
with a new one from Doug. Mine was leaking.
The new cooler is very efficient. Cools very well. I flew this week on a
90 degree day. Had the cooler door closed completely to get the
temperature up.
Chinese cooler is not a problem.
Call anytime.

Could be. I know Richard=99s/Aerometal=99s engines are outstandi

They sent the smaller suction jets which helped the CHT. Richard thinks tha

I fly and M14P powered CJ. It has a Chinese oil cooler. I replaced mine
with a new one from Doug. Mine was leaking.
The new cooler is very efficient. Cools very well. I flew this week on a
90 degree day. Had the cooler door closed completely to get the
temperature up.
Chinese cooler is not a problem.

I fly a CJ with a low time M-14P. In June here in central Arizona
we=99re seeing temps around 110=C2=B0F on a routine basis. Bought
a new, stock CJ oil cooler from Doug. Oil temps have been fine.

Jon;
The temperature numbers you listed are pretty much what one should expect f
or 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 insta
lled new cylinder barrels. If indeed the overhaul facility is a reputable o
rganization you should have a multi page overhaul report detailing all new
components and details of all the inspection, repair and restoration proced
ures complied with.
Best;

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, aut
o 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 s
uction 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 an
d 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 ca
me 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 10
00 rpm, oil pressure now below 1 bar.
Ideas?
