Howdy Scotty! I have a 2014 Toyota Tundra 4x4. It has the IForce 5.7L with approximately 77,000 original miles. The issue I have noticed only happens on cold starts and it doesn’t matter what the temperature is. The engine is making a ticking noise and eventually goes away after I drive it and it warms up. I have heard that this is a common issue with the Tundra 5.7L?! Shouldn’t Toyota do a recall for this issue? Bad timing chain tensioner? Or bad lifters? Would love to hear your opinion on this!
Check your valve lifters-they might be sticky.
Scotty posts an answer on this forum if no one else has responded already, so he won’t respond to your question now. However, sometimes he also takes a question (that already has answers) and addresses them in his YouTube channel, so he could still answer your question there. You won’t get any notification so just have to keep watching daily and maybe with some luck he will answer it.
Toyota AR-FE (4 bangers) engines had a similar issue. It made ticking noise right after it started and went away as the engine warmed up. It turned out that it was part of the design. It was something with the valve train and their VVT system. It was nothing more than a slight annoyance in case of the AR engine, didn't affect the longevity of the engine at all. I'm not sure about the UZ series engine(Toyota V8), but since they share similar VVT system, maybe it's that?
I appreciate everyone’s input. Does Scotty actually respond to these questions? I understand that it has to almost be impossible to answer everyone’s questions. {black}:hi: {black}:hi:
