2010 Knocking and Thunking on Idle - with video/audio

Is the engine burning oil? How bad? If it's not too bad, the head gasket should be the
least expensive way to go. I changed mine at 301,000 miles and now have 50,000 miles
since replacing it.... How many miles a year do you drive?

 

It's cheaper to replace the engine than head gasket where I am. Did you get the JDM engine? How did it work out? I'm not burning any oil. I drive about 20,000 miles a year. This is not some thing that I can do on my own, mechanic will need to do it. The labor for the head gasket is thousands more. This way with an engine I get a new intake manifold, EGR cooler, etc. Did you like the engine you got, and who is the supplier?

 

It is very much so and the newer 2024 Go sit in one of those It's like a Tesla Very cheap interior I pinch myself when I sit in a Tesla and listen to my buddy tell me yeah this car can go you know 500,000 miles and I'm like hey you'll be sitting on seat frames and have wires sticking out of the dash with momentary contacts which is wired up and stuff it'll be mad Max in the thunderdome for sure there is no way now let me say this go sit in a generation too and close the door that's 04 to '09 hear that thud lean against the front fender You won't put a dent in it with your knee bending over to change the spark plugs like you will Gen 3 and forward . The planned obsolescence vehicles are not dad's Toyota and I know this The new folks coming along 150,000 miles is like a million years to them they've gone to space and back of course you know these are people that have been raised in the house and never been outside that sort of thing so that's a lot at play here.

 

Maybe. Still, the rationale to replace everything, with someone’s unknown engine, especially with yours not an oil burner, has its pros and cons.

 

I didn't get another engine. And I would get a remanufactured one, NOT a jdm.
It is not worth the risk for me.
It's good you are not burning any oil. You need to shop around and find someone that will
replace the headgasket for a reasonable price.

The engine for the prius is not any different than any other engine. You don't even need to mess
with the hybrid battery or anything related to it. I would remove the Orange lock though, JUST to
be safe, and remove the negative terminal on the 12v battery. If he can change the head gasket on
a non hybrid car, he can do it on a Prius engine.

You won't get a new intake manifold, cooler or anything with a new/remanufactured engine. Unless
you buy it. They don't come with it. Some jdm motors have them, but not all. It's a guessing game.
I've got 50,000 miles on the new head gasket. I changed all the fluids and cleaned the egr system two weeks ago.

The coolant level was at the mark I put it at when filling after the head gasket job. "Maybe" ever so slightly
lower. I didn't mark it, but it was just above where the 2 halves are sealed.
