575M engine noise after service

Check valve timing! Most likely the left belt incorrectly set and from what you describe by more than one tooth! Prepare for some hard talking to the garage owner. Hopefully the valves haven't touched any of the pistons, or each other, or you are in for a major repair.

 

Sounds like valve timing. Is the car back firing through the intake or exhaust? Exhaust manifold glowing on that side?

 

I would not drive that way, nothing good comes of it. I would speak again to the shop that serviced it, via email if possible so you have a record. Tell them it does not sound right or run right and needs to be fixed. If they are unable or unwilling you'll need to take it to the local dealer and expect them to cover the bill.

What state are you in?

 

If you don’t mind me asking, was it Ferrari Sydney or an independent? Hard to know who to get to look after these cars in Sydney

 

Good evening. Sure sound like the timing is out. This could be from the lower pulleys when they did the bearings.

I had a confusion when I was in timing belt system and didn’t go any further until I got the best advice from the Pros and people on this forum. I thank them.

Please don’t start the car and have it sent to a professional who know these cars.

 

What period of time transpired between "recently" and "now"?

Did the car run OK when you picked it up from dealer after the "recently" stuff was done?

What is the "significant noise"? The noise of engine is significantly different when running on 1 bank and even more weird with enough random misfires over the 12 cylinders. We talking rattling metal? Squealing bearings? What?

 

He has no need to diagnose the issue. He has a need to get the shop to take his complaint seriously.
