So, I was doing some work the other day and went outside to check on my peat farm. Instead of a peat farm, I found a nice crater had replaced it. Obviously I had issues with my combustion engine. Luckily, my peat overflow chest was intact, but the rest of the machines were gone. I had been cooling my engine using a Aqueous Accumulator and two source blocks, and yet I was still having cooling trouble. The engine at my oil processing plant hasn't blown up, but it is cooled by a Buildcraft pump/water source. How can I avoid this explosion from happening again, at least until I get enough peat to switch to a peat engine? And why didn't the Aqueous Accumulator cool the engine properly? (This is the DW20 pack, so feel free to provide suggestions using any of Direwolf's mods.)

I would take a wild guess and say that the power wasn't being used. If the power from any engine isn't used, it'll back up in the engine, and cause it to heat up and explode, regardless of other cooling factors.
It's a good idea to either use an engine that will not quite, or only just, provide enough power to the device, or set up some sort of monitoring system, to turn the engines off when they're not needed.

Connect exploding engines with redstone energy conduits, they will dissipate excess MJ. Unused MJ will make engines explode regardless of cooling. As slow as peat farms go, I'd just use some peat engines to power it. Any engines you use for forestry farms that don't need constant power should be turned on & off with some sort of timer or sensor to save fuel. Timer+state cell to run them for a set period every so often, or a gate to turn them off when they can't store anymore MJ.
I can't speak for DW pack but after updating to Ultimate 1.02, me and some others have encountered bugs involving Forestry Multiblock Peat Farms consuming incredibly large amounts of water. I had a medium sized multifarm (I assume that's what you're using, if not then ignore this post entirely) hooked up to 8 Aqueaus Accumulators (just to test it out) and still running out of water. Maybe you updated the pack, the bug occured and your water reserve ran out and was unable to cool the Engines?
That or an energy explosion as stated above. Use redstone energy conduits and cells, and switch out combustion engines for something a little less temperamental.

More likely to be a chunk loading issue. If one of the two sourceblocks of the accumulator is in a different chunk than the other, you might get a situation where only one of the two chunks is loaded, and then the accumulator doesn't realize it has a second sourceblock and won't output water.
Also, peat farms, running out of water how? I had a multifarm doing peat in my test world, and the peat matured so slowly that the multifarm had maybe one block to harvest per minute. During that time, a single aqueous accumulator should easily generate more water than the entire internal tank of the multifarm can hold, much less eight fo them. I've also run a maximum size tree farm, which is pretty much doing a block every couple seconds, and a single aqueous accumulator wasn't breaking a sweat trying to keep it topped up. If there's a bug, it's gotta be a really weird issue where no water refills at all. Again, check your chunk boundaries.
Keep an eye on your water consumption metric though - the green tab on the right side tells you what modifiers currently affect water consumption, while mousing over the four symbols of the multifarm type (in this case the four peat symbols) will show you the actual water consumption in mB per block worked. The largest modifier to water use is time elapsed since it last rained, and if it never rains (like in a desert biome) you can get up to 25x water required if you let it run long enough.
Forestry has a rainmaker machine that can start and stop rain at the player's will. Try it.

I realize this. That's why I said it was a bug. It was running fine for DOZENS of hours off of one Aqua Accum.. Then after updating Ultimate to 1.02, the first time I check it I find there to be an infinite water sink. I rebuilt it several times and every time after placing the first watersource it would continually try lose water and not progress any further. Anyways I've already reported it on buildcraft forums and it seems others are also having similar problems.
I didn't mention the fact that I was using an old Forestry Peat Bog/Turbary setup. The Aqua. Accum. was cooling a Combustion Engine. I rebuilt the setup to use Peat Engines but I have to wait for the Turbary to finish removing the existing farm due to the Peat Bog not detecting the existing farm. Thanks for the help guys!
