the pipe is just jammed in there and siliconed sort of around. if you really try you could yany one out after a few years.

the oil onto the extractors would make a heap of smoke. get a short pice of metal pipe on there and a hose to the pcv valve into the inlet manifold... t might be there sucking in air if there is no pipe hooked up to it.

if our running the stock carby still.
