Oh man, that really sucks. I hope it gets resolved. If it had the 22re pistons, I would think your compression would be north of 175psi. The non-turbo head is actually a plusIMO.

Good luck.

Hope you get good news by Christmas!

Any updates?

Oh man....I am hoping for a fair solution

Yikes! I didn't see that one coming! What are the options? New block? bore all od cylinders? Sleeve?

I'm not carzy about "mechanic in a can", but I have used "Sea Foam" on occasion. can be used in the fuel or through a vacuum port.

It the cold start injector was leaking, I would think it would affect allof the plugs.

Yep, you could be getting lazy. changing injectors is a 2 hour job at most. You have spent more time than that posting. just say'n!  Smiley

The injector rebuilders That I mentioned in your other thread will supply all of the O rings and pintle covers. Maybe it doesn't show up when the engine is cold is because it simple needs a richer mixture until it warms up.

Ok. It is something only affecting the #1 cylinder. You say that you are now convinced the plug is fuel fouled and not oil fouled. If it was oil, then your choices are valve stem seal, or worse, broken oil ring on the piston. A broken oil ring would still give you good compression and leak down numbers, but would foul the plug and burn oil like a diesel. Let's hope for fuel/spark. The easiest fix is new/plug/wire/cap. If that doesn't work, pull the injectors and send to Osidetiger or RC Fuel Injection or other shop that specializes in injector rebuilding and cleaning. Most shops over a 1 day turn around and cost between $60-$100. You will get a chart with before and after specs and spray patterns. It has got to be one of the above issues. Anything else would affect all 4 cylinders IMO.

Sounds like you are doing all the right things. Have you actually swapped the # 1 plug with another too see if the plug was and or just keep cleaning it and reinstalling it back into the cylinder? Have you checked the spark plug wire?

I assume there are no codes, that would be too easy. Do you have a wide band to check the A/F? Sounds like the ECU is creating a bit of a lean/rich condition due to bad sensor feedback or maybe something as simple as a bad plug wire.

I think it is electrical though. I'm an old guy. Back when the earth was cooling off good and we all had carburetors, we had a saying: "When you think it is the carburetor, check the ignition". We didn't have OBD's then, we had a Sun Scope and could watch what was happening electrically on each cylinder. I would check the spark plug wires with an Ohm meter. Check the coil, igniter, etc. I would check all of the pins out on the ECU as per the FWM. Then I would fire it up and pull each spark plug wire off of the cap and check the spark color and gap jump. Check the RPM drop on each cylinder when the wire is removed completely and see if they are relatively equal.

Valves set properly? Sticky valve? Hold a playing card next to the tailpipe and see it sucks in when the stumble occurs. That could mean you have a valve sticking.

Good luck!

I've had a bad O2 sensor before and the result was sooty plugs like you describe. Is it all of your plugs or just #1? Have you ever had the injectors cleaned and balanced? Costs $60-$100. Are you sure there isn't any oil fouling at the electrode?

How loud is the "pop"? The idle is up when it is cold. Have you tried increasing the hot idle speed to see if that helps?

A couple of years ago I tested all of the values possible at the ECU as per the FWM. Took me  a little over an hour.

Yes, kinda like changing out a cam the same way,  but I never wanted to try it. Better chances with a MLS gasket

Looks great! You are right about no one wanted to tough your truck without cost some big $$$ plus your 1st born male child. I completely disassembled my truck and sot it myself, but it helps to have your own spray booth. The results are night and day different. Good luck with the details!
