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.

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

Every electronic fuel injection I know of runs forty pounds, screw
