Buildcraft 2.1.1

Hi people, sorry for the delay... In my defense, I'd like to say something: do NOT place extraction pipes with Buildcraft 2.1.1, it will crash the game... and you won't be able to keep that map. So yes, I lost the map I was working with XD.

I'll be using a new block from RedPower (version 1.7.1 is out, by the way): the repeater. Yes, there is already a repeater in the game... but this (that does not replace the old one) has a maximun delay much bigger, and can be placed like any other logic gate (on a wall, under the roof...). Here is how it looks like:

Here you can see four repeaters at several delay adjustements. They seem to be a lilttle buggy, at least visually, but they work well. I'll be using them so several stacks of engines will start at slightly different times, producing three "ticks" really quickly instead of pulsing at the same time, wasting two of those ticks.

Anyway, I made a video of a strip mine operation (a quarry at its maximun coverage) and its feeds. You can see it here:

There is a reason for the separation between the oil tanks, and I'll explain it with another, much shorter video at the end of the post. Meanwhile, let's talk about the oil, the pipes, etc...

First, in case you didn't knew, oil is a new finite resource that is treated like water in regard to everything but Buildcraft 2.x.x (dolphins can spawn in oil pools, for example, if you have installed Mo'Creatures). Being a finite resource, you cannot create infinite sources like we usually do with water. Also, the only way to put oil inside pipes is by using the new oil pump (made by putting an oil tank over a mining well in the crafting grid), and there is no way to take the oil out, the only possible destination to the oil is an oil tank or a combustion engine where it will be consumed (you cannot extract oil from the combustion engines).
By the way, you can place anything connected to an oil pump, like a lever to power the attached engine.
Sadly, oil is not affected by the special effects of insertion pipes or golden pipes, but iron, stone, cobblestone and wooden pipes work as usual.
Placing a wooden pipe between two oil tanks will mean that you might have to take a wrench and rearrange manually the direction to where they point, so do as I did in the video and put a stone or cobblestone pipe between the wooden pipe and the target oil deposit.
Now about behaviour, it seems like each block of oil is "divided" into three or so chunks, so wherever you have a point where the oil can go two or more directions it will go all of them at all, stopping moving until it has enough "mass" to move (so, until more oil gets divided and makes for a full oil block in each pipe). So you will be seeing lots of "leftover" oil everywhere.

As for advice when using all this, I'm using Eloraam's light blocks to know, at a quick glance, which wooden engines are working and which ones are not. Also, remember that now the engines will cool down on their own, and they won't explode as long as they have something to do, regardless of their color (heat level).

I'll start looking into Eloraam's other new three blocks for the weekend or so (I'm quite useless with circuitry, I think I said that before ^^), since there is nothing more to do with buildcraft right now. And without further delay, here is the video about how not to place the oil tanks:
