360 spider knocking sound, engine comming out

I will say a small prayer for you.... I have seen this mess up the top end of a 360 motor first hand at a shop I visit occassionally...
The pre-cats get sucked back into motor and do extensive $$$$$$ (5 digit) damage...

Hopefully you are lucky...

You can hear a noise similar to lifter clatter when the headers start leaking, but usually if it is caught early enough there is no damage to the engine. Why is the engine coming out? Did they borescope the cylinders and find damage? Do you have poor compression and leakdown numbers? Kind of hard to diagnose over the internet, but if you think it sounded more like lifter noise than rod noise, I would recommend more diagnosis before pulling the engine.

 

Rifledriver has lots of experience with this problem. PM him Ting. Any sign that they were going out or did it just happen?

The tap tap tap sound is the precat material stuck to the top of your piston and slapping the cylinder head each time it goes up and down. It will dent your piston and possibly mess up the valves. If its just one side you can just pull that head (repair it)and put aftermarket headers on the car. Fabspeed has them.

 

text rifledriver I believe he has some in his shop with this exact scenario if memory serves me right...
Thought I read a post a couple days ago regarding header failures he posted in regarding possible warranty scenarios as 8 year 80k mile warranty because of headers considered part of emissions system... You may wish to go at this angle & get to a Ferrari dealership for a battle with Ferrari on a warranty claim for the failure of the headers...
Helps I believe if your system is stock (no tubi etc...) nothing they can exempt because of a system change (still can fight it but easier if stock system)
I will look for link on search..

He's got TUBI and the car is 01 so it would probably be out of the 8 year warranty unless it was late production. Ting you have bad luck with Ferrari's dont you.

 

they smoke tested the engine no leaks, the mechanic had the sound narrowed down to the lower passenger side of the engine, and had to be able to get to it to figure out exactly whats wrong. the pre-cat manifold insides on the passenger side was loose and had lots of loose little pieces breaking off and falling out when it was detached and removed from the engine..
the mechanic told me someone at richambi suggested that the little fragments got sucked up into the cylinders.



I was talking about a cylinder leakdown test, not a smoke test for leaks. I would still recommend using a borescope to inspect the cylinders through the spark plug holes, that way you can narrow down which cylinders are damaged. As said in another post, if only one side has damage, you can save on labor by only having the one head removed, which can be done in the car.

 

You should do a compression and leak down test but those pieces can do a lot of damage to pistons and combustion chambers that does not result in loss of either. Also the pieces will go upstream into the intake manifolds and plenum chambers so particulate matter can cause damage on the other bank.

Sorry to hear and sorry it is out of warranty.

Do you have a Tubi or other aftermarket muffler?

 

You only drove the car 1/8 of a mile since what?

 

You mean you didn't wait until you couldn't hear the radio over it anymore?



Seriously, you'll just have to wait and see.
