 Subject: Still Pinging WTF???
IP: Logged
Message:
I have tried everything I can think of and My truck still pings under boost. I have Autolite 3922, 180 thermo, BTM is set at 2degrees per Lbs of boost starting at 1lb., 24lbs injectors, the IAT is set at 12 o'clock, and I have a boost by-pass valve. The temp. guage stays well below 210, oil pressure is fine, no oil in coolant or coolant in oil, and no loss of oil so I don't think I have a head gasket problem. I always use either Sonoco 93 or 94. I haven't changed my cap, rotor or wires but I don't think that is it or is it? Any help will be greatly appreciated.

Yeah still have the beer barrel. I noticed some oil down there but it doesn't seem use any oil. Is that an indication I have the dreaded belly gasket leak or could it just be the PCV system?

They do have some oil in them from the PCV. You said it was under boost right? Then oild couldn't get in under boost only under vacuume. I have heard Bernd say to go get the latest ping flash from chrysler and see if that helps. He only reccomended it in persistant cases kinda like yours.

If your pinging under boost, And the BTM is cranked up, it should have compensated for timing plus some. I don't think the "Flash of death" will do anything but piss you off after you fix the problem. If it pings just before boost the concider the flash. Most people running s/c'ers are set at 1deg with 92 octane.
Mine didn't use oil (at least noticeable amounts) but I had the oil in the bottom of the keg. I'm thinking that when your not under boost is sucking oil, just enough to get things wet. A fine oil mist is not critical until you’re under boost. I pulled my plugs before I tore into mine to see if I could detect anything, no positive signs of oil were found. I did however find #5 plugs electrode busted. I suspect it's from the detonation. Replacing the plugs didn't help I still had to tear into it.
If you find you have to get into the keg, and you keep the keg, a 1/8" bead of red RTV on the gasket seems to be doing great for me with a new gasket. I have 4k on the repair and I have a heavy foot. Get a hold of an inch pound torque wrench, it is critical on the torque.
I hope this helps

Thanks guys!! I think EyeTrip has the right idea. It only happens under boost and then only when it gets warm. If the motor is cold of I just started after setting all night no ping. After driving for 20 minutes or so it pings. Drtswinger do you still have the Keg or do you have the M-1. Looks like the M-1 is in my very near future.

I was running 10 pounds on a stock 5.2 with the boost retard set to 0 degress per lb. But I am running a Vortech S-trim and not the powerdyne. No pinging.

Powerdyne, Vortech, the ONLY diff is that the boost curve is different. If your running 10# it doesn't matter what puts it in there. Think about it.

A little more info. for you. I've noticed that I only get five pounds of boost now, were as I used to get six pounds. I think it is sucking the oil in under vacuum and under boost it is forcing it into the combustion chambers. I also noticed it blows a large cloud of smoke when it pings. So the M-1 is on order.

Thanks for all your help. I finally got my intake and installed it. I can now run 93 octane with the MSD pulling 1 degree per Lb. of boost and don't have any pinging. After I got the keg off I saw two areas were the gasket got pushed out. Got to love the M-1 no belly pan.

Drtswinger, I am thinking of getting the 9lb. pulley, because I lost 1-1.5 lbs. of boost. I haven't changed the head gaskets yet so I'm a little scared of 9 lbs.(but it would really be 7.5-8lbs.) Sorry to hear your selling the truck, hope you had fun with it while you had it.]
