Agree about hydrolocking. Do you think the EGR cooler is the source of blockage? Its upstream from the valve, so I'd argue it's less important....
Not sure why you're so sure. Maybe you can explain to me why my engine rattled at cold start but it doesn't anymore after a thorough cleaning and...
It makes sense, but I'm not convinced this is always the cause of the rattle!
Good plan. EGR is kinda... fun... Access is poor and the bolt and bracket design is wack. Don't even try it without pulling the wipers and top...
Nice one, thanks! I'm surprised that a bare connector would just float around the engine bay without a terminator if its for an option I don't...

Thanks for the responses. I'll run the car in maintenance mode and do the head gasket test on the coolant reservoir. I understand that rather than...
The car has 270k miles, it's rattling quite a bit at cold starts. I know 3rd gen Prii have issues with head gaskets, but I'll clean the EGR if I...
