TO PING OR NOT TO PING?

TO PING OR NOT TO PING?

Quick question...

2006 TJ
6 speed manual
4.0 liter with I-6
31/10.50/15 BFGs

When moving along at highway speeds or at lower speeds, does anyone
else's Wrangler engine sound like a 'rattlesnake' is in there? I am
not sure if this is pinging or simply just the normal sound of the
motor. Keep in mind that I do not use my 6th gear on the highway due
to the 31s. I am travelling along at approximately 65 mph and running
about 2400-2500 rpms when this sound occurs. If I back off the
accelerator and get to about 62-63 mph, the sound stops. It's not a
metallic type sound. Just a 'rattling' or 'purring' type sound. Any
insight?

Sorry but I forgot to add the following....

Since I have upgraded from 28s to 31s, can that cause the engine to
lug or ping? I generally keep the RPM's around 2200-2400 in 5th gear
(I have a 6 speed). In the higher gears after the engine is warm and
mainly while going uphill (little or big), I get this noise on the
passenger side that sounds VERY similar to the soft top side window
'pinging' against the metal support bow when the wind blows. I can't
quite distinguish if that's it, or if the engine is pinging because I
am not 100% sure whether it's coming from the front or the back.
It's
a high-pitched noise. It is NOT rhythmic or steady, but rather comes
and goes intermittently. This noise does NOT happen at city/town
speeds of 50 mph or lower. I ran a tank of 89 through her, and it
seemed to be drastically reduced after 1/4 of the tank was used and
for the rest of the 3/4 of the tank. I have now refilled again with
the 89 and the noise is back. I have not used 1/4 of the tank yet,
so
I don't know if it will be reduced again once I get to that point. I
do have a tendecy to 'stuff' as much gas in the tank as I can get
(even after the automatic shuf-off on the spout kicks on). Would
this
be causing the problem too?

Re: TO PING OR NOT TO PING?

I highly doubt you can make a 4.0 engine ping at 2500 rpm under almost
any driving condition.

At that rpm, you are way up in the torque curve and should have tons of
power to accelerate uphill fast even using regular gas.

My Jeeps have tons of power when fully loaded for camping at that rpm,
they will 'hold' 2300 rpm at least on anything.

I would be suspecting something else is making the noise.

I can only start a ping if I am way down into the mid teens for rpm or
have gas my CJ7's 258 doesn't like in it. (old carb engine, apples and
oranges to a 4.0's systems)

Engine are more prone to ping at lower RPMs when rate of expansion is
slower and load is high. You would know this if you had any realy
knowledge of this.

All the more reason it can ping because when engine is making good
torque it is near its VE peak (Volumetric Efficency) where effective
pumping pressure are the highest for its mixtures being burned and
these higher pressure need more octane

I take this with a grain of salt since you think 3.31 gears with 33's
is a great combo, you really do not have a clue what good pulling
power is. (you have very low standards)

Of course you would because you are clueless here

How much octane you need depends on engine temp, air temp, load,
humidity, altitude and well as deposits in engine from age and minute
oil usage too which lowers octane needs. Octane needs are not constant
and the trick is to use a high enough octane to meet maximum needs.
What people need themselves can vary and is not universal 87 does it
all as clueless here suggests. BTW, I do not use 87 in anything made
since early 80's.

Thanks for the quick responses.

SnoMan --
You're right, I really don't have much knowledge of what causes
pinging. I really do appreciate the fact that you're not being rude
about it. I was just a little confused though when you said engines
are more likely to ping at lower RPMs, then in the next paragraph, you
said that higher RPMs would be all the more reason an engine would
ping. Those statements contradict themselves (unless I am missing
something that I don't quite understand).

Any input regarding the 'rattlesnake noise'? It's just a soft
'purring' type noise. Not real loud at all, but does quit when I back
off the accelerator just a touch.

You said highway or lower speeds it happens
Tire noise?
Did you see if it happens when you in neutral?

Tracie, Mike was basically telling you what you are hearing was probably not
engine pinging. Snoman was trying to contradict Mike because that's his
mission in life when it comes to this newsgroup. Welcome to the club. :-)

Snoman has a real problem with Mike Romain, and he's only here because he
has stalked Mike to here from another other group. Mike has forgotten more
about real-world Jeeps than Sno will ever know, and is one of the most
helpful folks here.

Sno will undoubtedly make an "I've had Jeeps for a million years and
therefore Mike is wrong and I know everything" statement, but know that Sno
has only come to this group relatively recently and more often than not
enters a thread only when he's trying to make Mike look like an ass. So it's
really his advice that should be taken with a grain of salt.

If I was rude, it was not toward you. I have a running battle with
Mike Romain and some of his very bad advise. The true octane of a
engine as I stated is not a constant. In cooler damp weather you can
get by on less octane than in hot dry weather. I think the confission
you have about knock vs RPM is from I stated that engine are more
prone to ping at lower RPM (lower meaning below 3500 to 4000 RPM)
because of flame speed verse rate of expansion in cylinder from piston
velocity which increases with RPM. Also as I stated engine operating
at or near their torque peak have their highest pumping efficency and
highest cylinder pressures. Higher octane fuel burn a bit slower and
also resists self ignition better for tempatures and pressure in
mixture before and durring a normal burn BTW, the mixture does burn
not explode. When it exploded it creates the load knock that some hear
at times. (this is why diesels rattle because they are in effect
detonation engines)

The reason you are hearing it then is because the advance is still
rather high for best economy and power at the throttle setting and
octane of fuel is not high enough for that combo and current
environment and you are on the edge of more serious knock. (a little
light ping hear and there is okay you just to not want to sustain it)
Also, ping is very hard on your valves in that it can cause them to
vibrate in their seats and leak and in time cause them to burn. (this
is one of the main causes of burned valves in a otherwise normally
operating engine) Detriot today uses a lot of tricks to try to quell
knock to keep consummers happy with cheap gas with EGR and spark
retatrding being common means. EGR dilutes incoming mixture and
reduces availble oxygen which slows combustion and lowers peak
pressures too to limit NOx and a side benifit is it reduces octane
need a bit but it does reduce efficency too. Retarding spark is used
by basically all brands today as it is easy to do and keeps consumer
happy but it does lower power and MPG. I would suggest you try some 90
ot 91 octane for a while and drop back to lower octane in cooler
weather in fall/winter. (you can mix 87 and 93 together and get 90 for
about same price (50/50 mix) as straight 89.

No post here would be complete without a a comment from a troll with a
ego problem. See trolls like this would never be in a forum because
they would get banned. Only here can they act out their fantasies.

Here's those links again that snoball keeps hiding.

I could post more but I think these summarize his stupidity the best.

He wasn't referring to you Tracie, Snoman prefers to criticize Mike
Romain than add anything original himself. As Mike said, I can't see how
your engine would be pinging at 2500 rpm.

Re: Re: TO PING OR NOT TO PING?

Sno,

I, for one, appreciate your knowledge and contribution to the group, but
statements like "You would know this if you had any realy knowledge of
this." and "Of course you would because you are clueless here" are
irrelevant and worthless.

Re: Re: TO PING OR NOT TO PING?

Funny, there isn't much difference between Hispanic newsgroups and Anglo
newsgroups. I kept expecting to see "hijo de puta" in Snoball's message. I
put him back in my kill file of course.
