Hello and welcome to JustAnswer!
There are quite a few things that could be causing the tick. A mechanic's stethoscope can be used to try and pinpoint the source of the noise. It could be piston slap, timing chain noise if it's coming from the front of the engine, it could be the intermediate shaft bearing or chain, or it could be a valvetrain issue. If the noise lessens when killing a cylinder then piston slap, a wristpin or rod bearing issue is likely.
Blue smoke on deceleration or startup is usually caused by valve seals and/or worn guides, but blue smoke on acceleration is usually caused by a piston ring/cylinder wall issue. It's possible that there is damage to a cylinder or piston causing both of your issues.
