2012 bought with 157k miles

Yeah, not knowing the quality of the scrubber that was included.

 

@Mendel Leisk 's Moroso came with something different. I don't really know if buying a stainless Scotch-Brite would be any better/safer. Scotch-Brite is made by 3M so it's probably the best you can get (at least in terms of stainless steel scrubbers designed to scour your dishes, not catch oil!)

 

There's no brass filter. Inlet (from pcv) on the left, outlet on the right.

 

instead of the scrubber or as some sort of outlet filter? I don't really need to overanalyze this but don't want to pit my cylinders either.

 

Well, here's an idea! Apparently the Prius oil filter fits pretty well in the ubiquitous Amazon catch can.

So I started it up and no warning lights. Seemed to run pretty smooth:

However, after driving a few miles, I got home and popped the hood. It was charging the battery and was vibrating more than I expected (compared to my 2.4L CRV). There wasn't noticeable vibration inside the cabin...I just wanted to see so I popped the hood. The video doesn't capture it adequately; it makes the coolant hose and airbox look like they're just wavy. But the actual vibration was pretty noticeable. Both of those components moved back and forth about 5mm at a rate of maybe 10 times per second. It also sounds a bit rough. Of course, this is likely idling at a lower RPM than on startup, so maybe this is all completely normal (in which case I'd appreciate some confirmation!).

 

Ha! Yeah, cell phone. I think I have a setting for 60 frames per second but didn't turn it on. The vibration isn't out of the realm of normal for a 4 cyl (it's not as extreme as the old Porsche 2.5L they put in 944s) but it was much more than at warm up. Does the sound sound normal enough?

 

Yeah it was also sort of a strange situation where I had depleted the traction battery on my drive home. So it was idling in order to charge the battery, not the 1200 RPM maintenance mode. I would guess that the engine was only running at about 500 RPM based on the vibration. I suppose these engines very rarely idle at a complete stop like this, so it might not regularly have this type of idle.

 

Wait, does ECU need to relearn idle after cleaning throttle body, MAP or MAF?

Edit: I figured it couldn't hurt so I pulled the ground from the battery while I took a shower this morning.

 

Well, I learned about the "Prius lean" today...

 

What, you don't have a shower in your garage?
