This has Toyota fanboy written all over it. copy and paste of how engines work to gain credibility, not fully reading/understanding what is going on with the situation...just to say I won't like the LC because you are playing it off as "normal". FFS, I didn't tell them to tear apart my engine or trace it to a cyl 1 issue. They did that. I took it in for an "exhaust leak" which the service guy changed to "engine noise" in the description of the work ticket. I've tried getting into another LC as well... I've had others state their LC doesn't make that noise. It's not "Normal" and I don't believe its a wastegate issue due to the mechanics tracing it to a cyl 1 issue. All you master mechanics out here need to go call Corwin of Toyota in Colorado Springs and go talk to the mechanic yourselves. And please don't keep pushing this off as "normal" until you fully understand what's going on and or are working on the vehicle yourself.

Yes, a D-4S engine with a turbo (and wastegate) will make some funny noises, but C'mon guys the Toyota field tech will be familiar with those!
