Yet another heads thread

[Nero]

Heads are on and torqued with the head studs.

Started putting my rocker levers and push tubes on, went to bar the engine over, got valve to piston clearance issues.

Called Justin, he said I need to take the cam followers out and bleed the oil out of them.

Did two cylinders, sure as hell, makes a complete difference putting it together.


Fun never ends I swear.


Gonna try to get er running before the weekend is over.

So I have a good portion of the engine together, valve covers, intake, exhaust, just need to do injectors, pump, turbo, intercooler, so it'll be a minute before I'm ready to try cranking on it.

Since I drained the tappets, is there a procedure to re prime them so a push tube doesn't fall out and screw things up? Or just crank it til oil pressure comes up?

Edit,
Just found on another forums, bleeding the lifters and starting it up without them pumped up is what you are supposed to do, they will auto adjust.

Today was definitely productive. Valley pan, intake, push tubes, rockers, valve covers, injectors, pump, turbo, up pipe, crossover and down pipe all in. I also bolted up both accessory brackets, so just a short list of things to do tomorrow then its firing up time. Man I'm so exited, I miss my truck.

Just so i understand correctly, if you are using brand new lifters on a rebuild you dont have to bleed them? Im doing a full rebuild and my piston clearance checks out. I realize you are just replacing the heads so just want to confirm. those new heads look sweet. hope you get back together and running this weekend. Im over the rain already!

When I spoke to Justin, he said he originally used to clean and reuse lifters, but time wise it was cheaper to replace them when he builds engines, time wise.

To be fair, it did take me almost 2 hours to clear mine out. But I had already installed my push tubes and rockers, so I had to take mine off and reinstall them.

So to clarify, new lifters you should be good to go to just drop in and go. Just verify they compress by hand is all. After I drained all the oil out of mine I can compress all of mine with some effort.

Just for safe measure and peace of mind, I barred my engine over I swear 10 times to verify no piston to valve arguments of space occupation debates wasn't an issue.

Also, didnt realize you were so close. Over here in beaveron, have family in mollola.

Rain started really coming down when I was installing my collector and crossover pipe. Go figure.

 

[jwsfarrier]

thanks for the info Nero. Good to know about the lifters, I had no idea it would affect clearance. Makes sense. I really didnt want tear into my freshly sealed engine! Sounds like you are close to getting things all buttoned up. Look me up if you are in the area or need a dry shop. Enough with the rain already.

Well I'm running into a minor pickle, the cdd catch can I have doesn't appear to fit where I used to have it, because there's now a boost pipe in the way.

Any idea where I should install it? Can't be on the drivers side of thr radiator, that's where the remote coolant reservoir is

 

[Nero]

Well this seems to work for now. Its just sitting there. Took out the cruise control diaphragm, it didn't work anyways because I never hooked up the speed sensor when I built the truck.

Oh well.

Got er running, smoked like crazy and had some gnarly lifter tick. Shut down, retarder the timing a little more, lifter tick went away.

I can't rev it up to 2000 though to properly check timing, farts out white smoke and shudders like its starving for fuel.

So guess who gets to look into an e pump now....

 

[The_Josh_Bear]

It's not starving for fuel at idle and no-load throttle bump with your mechanical lift pump. Unless it's broken. Mine keeps up with my maxed stock pump to 14psi under load. And still isn't dropping off in pressure, so there's more left over. Probably not much more, but either way that's only your problem if the lift pump somehow died sitting in the engine block.

How long did you run it? Edit, doh you made a different thread with all the action!
