Try hooking the engine up directly to the quarry. If not, try placing the engine somewhere else, and have it like so, engine -- wooden hv pipe -- some power pipe -- quarry. Something like that. By the way, which version are you using?
I'm using latest experimental 393 I think it is, also I cannot find wooden HV pipe when looking trough NEI nor can I craft it. edit: Also hooking engine up directly worked.
