PING again. Tested Fuel pressure. Came out ok.
 

Hi all,

The Pinging problem continues. I tested the fuel pressure today and it
comes out at or above what Hesco recommends:

Hesco = 30 psi at idle
Mine = 31 -> 32 psi at idle

Hesco = 34 -> 38 when driving
Mine = "Hose not long enough to stick out of the hood to see to test"

So I couldn't test when driving unless I take the hood off which I'm not
opposed to doing I just didn't have time this evening.

So I'm at a loss what to do next. I was warming up to the Adjustable Fuel
Pressure Regulator as a fix but if I'm in line with the pressure I'm suppose
to have then doesn't that leave that one out?

Does this mean the 4.0L head is the only fix?


Agggghhhh :-(

Try the carbon thing... spray water into the throat while running.
You could have carbon buildup, causing high compression.

Hi Steve,

Did that already. Here's the list so far:

1. Raised the Octane level to 91
2. Changed plugs to cooler plugs per Hesco.
3. Retarded the timing 6 degrees with a DRB II (JeepsRUs)
4. Ran water through the intake manifold (a pint) to clear carbon.
5. Tested fuel pressure.

You mentioned before regarding my spark plugs:

"Black on one side of the white cone indicates bad or brand new
valve guide seals... "

Would this be a cause of ping?

I'm going to consult Hesco and JeepsRUs tomorrow to determine a course of
action.
Meanwhile I'm not driving the jeep as I don't want to do damage to the
engine.

I'll double-check with JeepsRUs and Hesco tomorrow on that figure.

No... ping is advanced timing, too much compression, or
lean. You just put on an MPI... look for vacuum leaks, is
all I can think. You've got a sticky one... maybe try mixing
some av gas in?

No... ping is advanced timing, too much compression, or
lean. You just put on an MPI... look for vacuum leaks, is
all I can think. You've got a sticky one... maybe try mixing
some av gas in?

Re: PING again. Tested Fuel pressure. Came out ok.
 

Every one of the Jeep MPI's call for 40 PSI until vacuum builds, then
back off to 30PSI. Hmmm... wonder how the new ones with the regulator
in the pump manage that?

Unless they've changed aviation fuel in the last couple years, then DO NOT
run any through your Jeep unless you don't have a catalytic converter. They
are not compatible with aviation fuel.

Try octane booster, then... that's what I'm getting
at. If it's a compression problem, then upping
the octane will cause it to go away.

Yup, much better suggestion. AV gas messes up a converter in a hurry, and
may also play havoc on an oxygen sensor. It sure was nice to use before the
days of emissions though. I lived about 3 miles from a very small airport
(only private planes now) during my early hot rodding years (I'm now about 8
blocks away from same airport). They still sell us AV gas if we want, but
it's more expensive than the Turbo Blue racing fuel we can get.
