Ok guys so after a couple of weeks I finally had some time to work on it a bit. While I’m not done with it, it does run again. Lesson learned as well. I got to buy some new push rods and tools. I started checking the spark and had it all 8 plugs and the checker I got also said they were getting fuel as well. Next went to compression. A big fat zero. So I realized all along that my suspicions about incorrectly tightening the valves came true. We took number three exhaust pushrods out and almost couldn’t get it out! It looked like an s. So out comes the borascope and there was no damage that could be seen. We replaced all the pushrods even though some didn’t look bent. Tightened the valves in the correct manner. Btw that sucked, it took three of us all thinking out loud to make sure it was done in the correct order. Why can’t it be simple. All evens exhaust then intake or something like that. Anyway I digress. So put it all back together and first crank it starts right up. Let it run a few seconds and no probs. Now time to change the oil, reconnect the exhaust to the manifold and check everything again for safety. Thank you all for your help.

I will sir. I’ve been busy with other household things and haven’t had a chance to get back to it! I will post once I get a minute or two to go over everything.

Thank you for all of your help. Here is my to do list for this weekend. I will post back with results and hopefully video as well.
Read up on setting the timing
Check the plugs and wires and firing order
Recheck timing/set the timing
Check compression dry/wet
Check rocker arm settings.
Get video of before/after everythingOnce again fellas, I really appreciate everything you have done and recommended. I’m hoping something here will work. I have had numerous people look and no one has been able to pin point the problem.

[quote=”619DioFan” post=49912]Just google rocker arm adjust for the truck , sure you will find something. take me too long to type it out ( sorry – very poor typer here ) use a spark plug tester to verify spark at all plugs. wet – dry compression test means- dry: test the compression as normal.
wet : add a little oil to the cyl and then retest the compressionif the compression changes dramaticly ( increases ) during the wet test then you probably have a ring/cyl wall prob.[/quote]
Ok will do!

[quote=”Wrench Turner” post=49910]perhaps I wasn’t specific enough. Please allow me the opportunity to clearify:
Q: When you put the engine back together, did all the spark plug wires go back to the spark plugs in which they came from? Similarly, did the spark plug wires go back on the distributor cap in the same order in which they were removed?
I only ask because when I did head gaskets on this engine, I also had to put in new spark plug wires which took a bit of time because they are all different lengths… so I had to devise a method to determine which plug wires would be suited for which cylinder in accordance with the firing order.[/quote]
I believe so yes, however, they off been of so many times since then that I will double check.

[quote=”619DioFan” post=49905]With the valve covers off make sure the pushrods are seated both on top of the lifters and under the rocker arms. did you do an initial adjustment on the rocker arms before trying the first start up ? since you mentioned no noticable firing on one side a compression check there might reveal answers. check it both dry and wet. the actron guage is fine. I have that same one. I am assuming the timing chain/gear assembly was not touched during the repairs. also , I would verify that all plugs are infact getting spark.[/quote]
Ok I will check the pushrods. We didn’t do any adjustments on the rocker arms. I think the only thing we did was just tighten the nuts. Do you know of any videos that show how to do this. Correct on the timing chain, it was never touched. We did check most of the wires for spark. I cannot confirm he did all because I was the one turning the key. What does wet/dry mean?

[quote=”Wrench Turner” post=49901]i hate to second guess you, but i only ask this because it was an issue during my head gasket repair:
Q: how confident are you about your spark plug wiring vs. firing order[/quote]
No offense here, I’m a rookie at this. Up until this point the most I’ve ever done related to the external engine only. Alternators, batteries and brakes, heck I’ve done more with lawn mowers than I have with cars. To answer your question, I’m not sure. The reason I say this is because I wasn’t the one that did them. I know the first time we looked at the book because I read them off. After that my friend said he knew it. I do trust him though. He was a manager at meineke until he realized he could make more installing house windows. I work at a hospital 12 hours a day, 4 days a week. I’m not off again until Sunday but, I will double check them then.

First with the key we bump started until we got close to TDC then we manually went the rest of the way. Then we pulled the cap and checked the status of the rotor. Tightened everything up an tried to start it. No luck. We then loosened everything up and turned 180 and restarted the process again. Still no luck. In order to use the timing light doesn’t the truck have to be running. When you had these problems, did the engine sound like it had compression. I will try to get something recorded so I can play it for y’all. Mine sounds like everything is turning within the motor but no compression. At first I thought the starter had went out or wasn’t making contact with the flywheel. It sounded like metal turning that’s it.
