The stock guage was half-3/4 that's where it's always been since I bought it a year ago. I know usually if a bearing goes the oil presure drops a lot so I don't think a bearings fried. Anytime I've heard a lifter blow off the push rod it knocks loud at all engine speeds same with a bent/broken rod. The 2 times I had it running the engine was not making any noises it sounded normal.

 

Did you try to turn the engine counter clockwise at all? Something is definitely jamming it from turning over. See if you can turn it at all with a breaker bar and socket to the left. It would be a terrible coincidence, but you seem to be having those with your truck as of yet, that maybe your timing chain broke and wedged against the crank gear or something of that nature. we will start at the top and work our way down. First take the valve covers off and check for dropped valves, broken valve springs, damaged pushrods, etc.. If all seems well in valvetrain land the next step will be to drop the pan and check for damage to the lower end such as bent/broken connecting rods, broken pistons, damaged bearing surfaces. You could even have a broken crankshaft/camshaft. The possibilities are nearly endless. Oh before you drop the pan completely you could pull the timing cover and check the tiing chain/gears. We will get to the bottom of this. It will just take some time and investigation.

 

Sometimes, the pinon on the starter jams the flywheel but, in this case- I think it's your intake and I will explain why.

Were there fluids inside the combustion chambers? Oil? Antifreeze? Yes? NO? I would rule out any gasket material being the culprit. It would be shredded by now.

Here's a possible scenario:

Intake leak: failed water seal around water port/s may have led to water in the combustion chambers via intake ports. If there's any water in any of the chambers- it's time to remove the intake, vacuum out the fluids with a shop vac.

That's one thing that would lead to slow crank times. It's also another reason why your starter got really hot. It's not that the starter is jammed or, that the it's semi-shorted but, due to the higher resistance, it's now drawing way more current to try and rotate the engine. The higher the resistance, the higher current draw, hence, the quicker the battery drains down, the faster the starter becomes hot etc.

Now that we have the whole story, I believe that this entire thing is rooted in your intake and with fluids in the chamber/s. That needs to be checked out first before firing it up again. Verify that first before taking anything apart.

If that turns out to be the case, I have a bullet proof method for prepping and obtaining leak free intake seals. When and if the time comes, just let me know and I will post it out step by step.

 

I tried pulling the plugs and cranking it by hand and with the starter, it still turned slow I thought that would rule out a hydroloc lock? I'm probably wrong. I did try to turn it counter clockwise as well with no luck.

 

And I blew all the chambers out with my compressor before I put the intake on.

 

Hi I have been reading the posts. I think you should do like speeddemon said and check the timing chain and gear. It could possibly be binding. If the chain and gear look fine i would take the chain off and see if you can turn the crank,if the crank turns try the camshaft. One of the two is causing it to bind.

 

I'm going to pull the cover today I'll have to pick up a harmonic balancer puller. This issue has baffled about 5 mechanics and a car builder since the engine runs fine when I can get it to crank. It's pouring where I am were getting the back end of the hurricane but I have to get this running. I'll take some pics when I pull the cover.

 

a buddy of mine was telling me when his crank bearings went it was the exact symtoms my truck has. I'm going to drop to oil pan and check those first since I have ran it low on oil a couple of times.

 

It is NOT your timing chain binding up. If it was, your truck would not run at all- period. You have another issue. If the bearings spun, yes, that would also create those kind of symptoms. However, you would hear that as a squeeling, metallic screeching sound. I had them go out once.

 

The other thing that will cause slow crank times is RTV in the chambers. If it's placed around the intake or exhaust ports, it melts, breaks down and ends up inside the chambers creating one gooey mess. Did you place RTV around those ports by any chance?
