car built and running but its lumpy, smoking out of the top of the rocker cover

So on from a previous post I got a fuel pressure reg so now the car starts and idles fine, altho there is smoke coming out of the rocker cover, im baffled by this and it still sounds down a cylinder, all leads are sparking and all injectors are squirting, ive tested this but one lead has a crack in it, part of the distributor has a slight crack were a lead plugs on and one of the rubber grommets beteen the injector and head is a bit out of shape and not a great seal, im gona have ro replace these but if I dont work im just throwing away money.

So before I do all this any ideas?

Compression test, having air/smoke coming out the breather is a sign of the engine breathing heavily, ie worn rings, poor valve seats.

What adam said. and it sounding like it's down a cylinder with smoke coming out of the breather sounds like a piston problem.
