To start it off I have a 93 fzj80 just did the head gasket and full valve job with an egr delete. Im hearing a knocking/ ticking noise now after about 2 months of driving it around. It only ticks at idle randomly and makes the noise when im barely on the gas. But once I put the truck under more load the noise goes away. Doesnt matter what speed im going as long as i barely push down the gas the ticking/knocking starts. Ive done some basic things like plugs and wires dizzy cap and rotor also checked timing.
