1990 4.2 tick
I've been having issues with a very elusive tick coming from my engine. it ticks sporadically at idle and consistently under load. I've pulled the water pump, checked the fins and bearings, and that wasn't the issue. i pulled the harmonic ballancer and timing cover to check that it wasn't an issue with the timing chain, it wasn't. as i was putting everything back on, i noticed the negative battery cable to the block was not tightened down all the way. could this cause a ticking sound?
