I was told this noise is coming from the lifters and this is not a problem? is this true?? I think this noise goes away after the car warms up but i don't know if this noise is bad or not?

i thought i'd heard its the water pump?

ticking from from left down low of engine bay?

Classic M113 ticking noise, I'm sure everyone here knows what you are talking about.

Yes indeed! It sure doesn't sound like a lexus engine.
