Is this the sound of a broken/missing apex seal?

samedi 23 mai 2015

I'll make this as short as possible, nobody wants to read too much:

-Drove in the rain, heard a pop and car died, I push-started while it was moving and came back on, but it was going bananas so I pulled to the side. ECU threw a P2070 Intake Manifold Tuning (IMT) Valve Stuck Open. Would crank but not turn over at all. Had to tow it home.

-Removed and cleaned SSV valve per Jon's video. That thing looked absolutely awful and it was getting stuck, it had been a while since I wanted to clean it but now I had a reason to.

-Had to deflood the engine after the install.

-Car turned on as usual after a deflood. I let it idle for about 5 minutes, everything seemed fine, idled okay, no weird noises, etc. Eventually it shut off. Figured it was normal.

-Turned it on again, wouldn't idle, had to keep giving it gas to stay alive. Car sounded weird, as if one rotor wasn't firing. Raspy and deep.

-Checked all plugs for ignition, all of them ignite.

That's when I heard something weird:

If I had the rear rotor plugs off, but the front in, the engine would sound a certain way when cranking. When I took the front rotor plugs off, and put the rear plugs in, it sounds completely different. Car won't turn on at all anymore.

I recorded the sounds:


Does it sound like the front rotor could be missing an apex seal or is that a normal sound?
