Blue Smoke all of a sudden??

[Dobbelaar]

So i had 2 bent push rods in my cylinder closest to the fan on the drivers side, causing a popping sound from my air filter. I took the driverside valve cover off and replaced the two push rods ... I also put the 50 cent fix of that side UVCH because i could wiggle it a little. Any idea why this would have started? i never had a bue smoke issue before? I also snugged up the injector bolt aswell.
