Lifter Tick !!
I just bought a 79 'F150 4x4 400 big block truck three weeks ago. I have put about 300 miles on it, and have been working on a few minor issues. Replaced ac/heater blower motor. Steering , exhaust were next on the list. Took it for a spin around the neighborhood, and when I got back I heard that ticking sound. It's coming from the valve cover around the number 3 piston.That dreaded lifter tick sound. My heart hit the ground!!! I imagine it's gonna hurt the wallet a lot. Where to start??!!

I was told it was a crate motor that was put in about 6 yrs ago. A high school boy used the truck for mudding. The father put a lot money into the truck. However somewhere along the line it had 2 broken leaf springs and sat for over a year. Got sold due to a divorce. Some older gentleman picked it up ,replaced leaf springs and sold it to me. He said it was too high for him to get in. Ha ha
I just replaced the spark plugs also.....which look well over due. Could the new plugs cause an issue ??? I know the tick was not there before I changed the plugs. ( Like I said I only drove about 300 miles )
It does have an exhaust leak at the exhaust manifold/ exhaust connection...maybe a bad doughnut there. But, that is on the passenger side. This ticking is on drivers side.
