could be a lifter sticking
lifters
The fuel injectors make the ticking noise you hear at startup, especially when the engine is cold (colder temperatures).
What causes ticking, check engine light, and the check gauges sensor to come on in a 1999 Dodge Durango 5.2L SUV?
The ticking sound is coming from the valve lifters. When the oil filter is changed, air is introduced into the system, which causes air bubbles to form in the oil. This causes the valve lifters to "leak down", which is what causes the ticking sound. It can take several days for the bubbles to dissipate. It's annoying, but harmless.
Possibly just an adjustment on the rockers. Hydraulic system. Hopefully that's it.
the noise coming from this truck is the uv goints
The ticking noises is the lifters slamming into the valves. They are not receiving the amount of oil they require to lubricate properly. Either the oil level is very low or something else is seriously wrong. Continuing to run the engine like this will lead to very early engine failure.
I have the same ticking noise and it seems to be louder on hotter days. I was told by the service tech it's due to the synthetic oil being thinner. I have my doubts, but that's what they said. Still researching for the answer myself.
the ticking noise is a small exhaust leak close to the exhaust headers or exhaust pipe near the engine.
Take it to a mechanic
The ticking noise is the metal cooling.
