Thanks Burgs, but it's not that motor; another car, although hooked up like that. BTW, old pic of that engine bay. I've since moved the firebottle to the trunk and replaced it with an Accusump
And thanks ByronRACE. Good explanation. Unfortunately, in NY, when registered under the legal and proper "homebuilt" vehicle procedure as a '98 Custom, the DMV inspection computers kick in a default '81 standards emission requirement (PCV valve and idle sniff test).
However, I think I will vent the other side to a tank as that sounds cleaner than venting all over the engine bay.
