my 83 elcamino 305 just started ticking last night like a lifter make me sad, i drove it all day yesterday and it was fine but last night i started it up and starting ticking, i tryed to use a wooden bar to feel for vibrations and it didnt feel like much . it was a quart or oil low i filled it and the sound didnt really go away . what do i do? is it something to worry about? the motor runs great dont smoke and has some balls for a 305 .... any advice or input? Thanks gbody freinds!
