Off topic but everything I own with a waterline floats. ;) How high is the waterline on that hummer? I'll try to look up what a provent 200 is later. If I look it up now I'll probably need one. :D

Got a question for you guys that build engines. You ever notice the difference when torquing heads when they are hot versus cold? I never thought about it till I read that some guys heat them a bit somewhere. 90 foot lbs suddenly turns into 60. But if you were to torque them hot that would seem...

You still have the iconel pressing against the sides. Since the sides do the majority of the heat sinking I don't think you would want any other material there. The quote I have right now is for stainless shims. .06mm $330 for 40 of them. Heat of the precup probably doesn't increase pressure...

Because they are heat sinked directly to the block they should not need to be inconel. The center part that gets super hot needs to be inconel.

I am pretty sure shims would fix it. Shims would bring the precup out flush with the surface of the head so the gasket can press on it. That would hold it steady. I am 90% positive.

Turbonator brothers are like, "shucks that's nothing" lol

LOL isn't that how it goes? Especially with a new to you rig. I am still going over my newish (to me) truck.

So this is a Manual build? As in no computer except the one you got for the 4L80E? PCS is better controller then the us shift. ;) I just had to jab ya with that one. But yeah fill out your signature info to include all the diesel rigs or all rigs that you work on. It really helps the guys...

Update: The waterpump backing plate that was suppose to arrive today turned out to be gaskets. And my main splurge for rockers from Harland Sharp showed up at standard ratio instead of 6:1 like I asked for. I wonder what else can go wrong. I'm down another week for the backing plate and if...

Ok I was wrong. there is a number on that tester. S60H Still pretty sure it is straight from china. The gauge is odd somehow. Doesn't look like a pipe thread. I haven't removed it to be sure but pretty sure it isn't.

Some no name from off ebay a while back. They weren't proud enough to put a name on it. That should say something but it saved me having to build one from a bottle jack.

ugh! If i could find a gauge id be happy but with this pump I don't thing it is possible to put a one way valve with a pressure relief in there. I guess that would depend on the valve. got any sources for either?

How many row core is that radiator? How big is it compared to our truck radiators?

I just realized I am not carrying an extra fuel pump. hmm Must be because I still have the one for the second tank hanging under there. Still I should have a spare because those parts house pumps are crap.

Perhaps no time or money at the moment? That is usually what stops me. :(

If was me I'd take that number and see if I could find a local parts house with it in stock. If not, oh well its only 5 or 6 days for shipping. ;)

I am assuming finding a 4 bolt fan is out of the question? Just for short term use?

So basically we have two leak point potentials, the pump plungers and the injector. High pop pressure can cause enough leakdown on hot thin fuel that it doesn't want to start? Hmmm I should think with lower pop pressures you should get more power since more fuel is being delivered. :) However...

It will be a db2 moose pump. If I don't like it I will just swap the one out of my current engine. It is a DB4 pump and I really like the way it has run. Might turn it up a bit if I do that. Though those pumps are more of a pain to turn up. I really like the Schweitzer turbo too but can't find...
