I have a very small ticking sound when I first start driving the truck. After a few blocks it goes away and may show up if I let the truck sit a few hrs. I was hoping it was an exhaust leak but am not sure. Hoping not a valve, but would that quit after a bit. The timeing of the tick would be close to one cylinder I think.

Mine does the same. Not loud enough for me to worry too much about it. Seems to dampen if I run 2-stroke in a tank of fuel.

could also be just a slightly noisy injector

Might try some cleaner or something, I have never done it and it has 180,000 km on it. I have had it from 135k. I just hate ticking sounds but, at least it does go away.

thanks for some encouragement.
