Hey guys,

I'm replacing my eccentric shaft sensor. As I'm getting ready to take the valve cover off I undid the 3 retaining bolts on the valvetronic motor expecting it to stay in there. I was following the Pelican guide and it said I could undo all of them, then use an allen key to unwind it and guide it out. Instead, it popped right out and the engine made a loud sound like gears crunching. Did I just ruin my engine?

You're supposed to set the VVT motor in service position *before* you removed the bolts. Hopefully, you didn't break the shaft off the motor. It's too bad that guide gave you incorrect instructions.

I don't think you ruined your engine, at worst you'll need to replace the VVT motor if the shaft broke off.

Thank you for the reply!
Motor itself looks normal. Shaft still on there. Any chance I damaged some other part of the valvetronic system or is the motor itself the main thing at risk when removing it?

Here is the TIS procedure for removing & installing the VVT Servomotor:

Videos found online, and a number of the various Vendor "How-to-DIY" articles omit KEY information. It appears best to read & compare Bentley, TIS and perhaps a Vendor procedure such as Pelican to make sure you understand EACH step listed in EACH source BEFORE wrenching.

Hope you didn't damage the Eccentric/Intermediate shaft.

Pelican Parts definitely says to put in service position before removing mounting bolts.

Sounds like OP is still ok though.

Damn I'm an idiot. Is there a good way to test if I damaged the eccentric shaft? If its damaged will starting the car damage the motor further?

The eccentric shaft doesn't usually get damaged by this. It's the shaft of the motor itself that breaks off. If it's still in one piece, consider yourself lucky.
