Not powered qooden pipes sucking out lava

[Angius]

As in the title. Wooden pipes are connectd to tanks on the bottom, there are redstone engines beind them, connected to redstone through repeaters. There's no redstone signal, but lava appears in wooden pipes - and further - nontheless.

Assuming I managed to read that correctly, what tanks are you using? If you used the TE3 tanks, having them set to output mode (orange on the bottom) will make them dump their contents into any viable pipe/inventory regardless of redstone signal. If you managed to do this with an AE or BC tank then that's more interesting and should probably be reported in the tracker instead of here.
