Question about 2004 Suzuki Forenza
Low compression in one cylinder blowing white smoke from tail pipe . headgasket was blowen fix gasket put top cams at tdc and now lower cam will only partially turn is it possible piston wall has crack
You need to start over with the timing process the valves are hitting the pistons because the cams are not in time rotate the pistons off tdc by about 90 degrees counterclockwise and reset the cams then turn the engine to tdc and put it together rotate by hand after installation to be sure it turns freely 2 full revolutions of the crank and all the marks should line back up

SOURCE: I just rebuilt my Sidekick
Did you pump up the lifters with oil? They are what oils the valves. As the motor runs they act as pumps and hydrolic shock absorbers at the same time. They pump oil up through the push rods. So when you try to adjust them they collapse and don't fill back up.
A drill press and push rod is the best way, tighten the pushrod into the chuck. Leave it off. then place the lifter in a small bowl of oil and press it down with the lever on drill. do it over and over until it gets hard to pump.

Partially, this sounds insane. Here's what I would recommend doing just to try ... forget PCV, first of all. Next, drain all the oil out (Keep it, should be good) and flush the engine out by pouring maybe a quart-a gallon of kerosene down it. If there's anything blocking the flow, that'll get rid of it. Drain all that out. Put in a new oil filter. The goal is least resistance possible. Put all the oil back in, start it up. Rev to ~2000 RPM, until it gets up to temp. I'd suppose that this would check to see if the rings were damaged some how. If it still smokes, I'd be curious to know if your valve seals need replacing, or having a blowby test done, see if oil gets in.
