No fire in #4 after rebuild

[wb1895]

Tried removing the injector again to make sure it was spraying fuel. It is spraying really nice. So, I removed the valve cover and the rocker arm, to inspect the top of the valves. All of the valves looked the same and had no noticeable play or differences. I put the rocker arm back on, made sure the valve lash was still in spec, and ran the truck. The valves all opened and closed as they should, and again no notable differences, but still no fire on #4. The next step I am going to try is to put some compressed air into the cylinder and listen for leaks. If nothing is heard, then I will have to pull the head again.

Where should I look for a compression tester that will work with the LDT? I want to make sure that it will have an adapter that will fit

White tractor engines have a tester that fits. I would contact "Maibach" tractor supply. I bought one years ago, works great.

Okay I hope ya'll are ready for an awesome "I'm and idiot" moment..........

So I still could not figure out what the heck to problem was, knowing that I was getting fuel, air and all the moving parts were new, so I went back to the TM and started looking around for a possible answer. While I was flipping through the pages I came across the injector line to injector diagram. I noticed something seemed different from what was on my deuce....then it dawned on me. I had the #2 and #4 injector lines switched in the HH. So, I switched them to where they should be and the problem was resolved. So, after all that digging, thinking, stressing, and pulling hair out it was a stupid mistake I made when I was getting excited about cranking the truck for the first time. With that being said, I learned my lesson of slowing down and paying attention to what goes where. Thanks for the advice and the words of encouragement.

Glad it turned out to be a simple fix

That's Great, good job finding the problem. That's one of the note to self moment ( remember to never do that again) lol

 

[MtnSnow]

Congrats on getting it going and that it was a simple fix other than the troubleshooting!

I would rather admit I'm an idiot then have to tear down my engine I just had rebuilt ! Good catch. Funny that the #2 cylinder was not acting up.

G'day everyone,....

Now I know it will actually run with fuel lines lines switched. For me it is not the things I think about that gets me but those things I discounted in the reasoning process. I should have seen that from here.
And Happy anniversary. Celebrate a new engine and the new marriage.

How does the engine run now? I put new piston kits in my engine and topped it off with NOS heads and I am still having a lot of blow by. I dont know if a NOS head is cracked or what. Im stressed and just wondering what parts you put in yours and if they are the same as mine. Thank you.

How do you know the engine has high blow-by? If the amount of smoke coming out the tube makes a big cloud coming from the truck, something is awry, if there is just a little bit o smoke or a light breeze leaving the tube, it's normal. The only way to tell what it is, is to measure it. A cracked head will show coolant in the oil, think about it, the casting will fail into the weakest point, most of the time from the injector bore to a valve or between valves. All of those points are cooled by the coolant, so, your symptom will be steam out of the blow-by tube when the oil/coolant reaches 212° and coolant in the oil.

Idling or operating at no load is the worst thing for a new engine. Run it hard.

I replaced the pistons, rings, sleeves, bearings, lapped the valves, and all new gaskets. I still have noticeable blow by but it is not nearly as bad as it was. The longer I run the truck the better it runs, and the less the blow by I have. Unless you have a cloud of blow by I would run it via the break-in procedure and see how it goes.

Can you take a short video of your blow by and post it up?
