| Subject: | One Cylinder on an M14 Running Hot?? |
Hello All,
I would like to ask your opinion on an engine issue: I have one cylinder on my
M14P that is running about 40 deg C hotter than the rest. (I have a fancy, 9 cylinder
CHT instrument, like a JBI). It was #3 running hot
I swapped the leads with #4 cylinder and the indication followed the cylinder -
#4 is indicating hot now = so, in fact the cylinder #3 is running hot and indicating
properly I think....?
I checked the intake tube for tightness and such, pulled the plugs - they look
OK, perhaps a bit white....ish (hot) but not real bad.
I am not sure what to check now or where to look for the problem........and ideas?
I really appreciate any advice or help you can provide.
Thanks all!

I'm not clear about what you said.=C2- When you swapped the probes betwe
en #3 and #4, did the #4 cylinder indicate hotter than what it was before y
ou swapped the probes?=C2-

I'm not quite clear on what you just described.=C2- So let me ask this.
=C2- When you swapped the probes between #3 and #4 cylinders, did the #4
cylinder read hotter than what it was before you swapped the probes?Dennis

Hey Dennis,
Sorry for the confusion. #3 has been indicating hot for a while, but only at high
power. At idle and low power it was normal.
So I swapped leads with #4 cylinder. Then #4 was indicating hot and #3 was normal
- so I assumed the leads are OK and the #3 cylinder is actually running hot.
:)

No, I disagree.=C2- If after swapping the probe #3 was normal and #4 was
reading hot, then your problem is most likely a bad lead.=C2- ie:=C2-
The problem followed the probe.=C2- Did not stay with the same cylinder.D

Hi Dennis,
I am not sure that is correct, and sorry if I am being dense but....
The #3 cylinder was indicating high to start with. So I swapped leads with #4
cylinder - put the #3 lead on #4 cylinder, and vice versa. So....#3 INDICATION
is reading #4 cylinder....and #4 INDICATION is reading #3 cylinder.
After the switch, #3 indication (#4 cylinder) was reading normal, and the #4 indication
(#3 cylinder) was reading HIGH!
:)

n carefully for valve leaks.=C2-
