Interesting... Looks like the 400, 400i and 412 all use the same mount, buffer and heat shield.
From what I can gather from the 412 Parts manual (and if I understand Italian correctly... hahaa), it appears that when the stock runs out for the buffer listed as part # 104956, it appears that the follow-on part number will be: # 131252.

Checked the parts manual for my 400 Auto (carburettor) and this gives the following:
The mounting that goes onto the engine block is part number 105263
The rubber engine mounting itself (called a 'tampone sospensione motore', which translates as 'engine suspension pad') is part number 104956. This is listed fop all 400 carburettor cars.
The heat sheilds are shown as part number 105266. In the diagram these look like they are quite thick but in reality they are just thin sheets of aluminium that curve around the rubber engine mountings. There is, however, an air-gap of around 5-10mm between the rubber annd the heat shield.
Hope this is helpful.

OK. I think I've got a handle on it now! Just got the 412 Parts Manuals, and here is what I found:
The Motor Mount (that bolts to the Crank Case) # 105263
The Rubber Buffer (they list 2, One is for what they call: Until Exhaustion # 04956, and the other is After Exhaustion # 131252).
The Buffer Guard (this is what appears to be some sort of guard to protect the rubber buffer from heat and oil. # 105266
Hopefully, this clears things up!

Could be the answer Mike. Let us know what you find. |

Ooops. Looks like I need to check my eyesite! hahahaha.
I looked in my 412 Service Times Manual again last night, and saw that there are 3 elements to the motor mounts.
There is the mount itself (bolted to the engine), the buffer (the actual rubber that screws into the mount and body frame), and the 3rd piece is what they call the "Buffer Guard". Its the same shape as the round rubber buffer, and fits over the top half of it. I'm sure this is used as a protection for the rubber from heat and/or oil.
Soon as I get the parts manuals, I'll list the part numbers for all (3) items.

Like on Simons car it could be a after thought to fix a problem affecting the mounts. |

Not sure if it does or not... I've not seen the car in person. Only images sent via e-mail. The mechanic at Continental Motors that I spoke with, did not elude to them having heat sheilds around them.
In fact, I have a copy of the 412 Service Times manual, and it shows the mounts, but no heat shields around them. I also have just purchased the parts manuals as well (but have not received them yet). I'll check and see what shows up on them, and let you know.

Michael, Just curious does the car have the shields on the mounts? |

Thanks Guys. I just spoke with the Mechanic at the Ferrari dealership who has taken care of this particular 412. He indicated that one set of mounts that were put on, were faulty and had cracked within a few thousand miles of being installed. The original ones had deteriorted due to being fouled by oil. Apparently, everything is OK now. This set has been on for over 20K and no problems.

Michael, there is your answer. Does yours have the heat shields? If not that could be your problem. |

I have a 400 and I have aluminimium heat sheilds around my engine mounts. I follow anything to do with 400/412 cars quite closely and I have never seen anything about this being a design fault or a common problem. Funnily enough I was recently looking at mine, or what I can see of them under the heatsheilds, and they look fine. |

I know not many of us have had 412s on here but maybe those who know of this problem could help Mike who is interested in buying this car. |

Mike, If they have been replaced several times it definetly is a indication that something is not right in the design. I have not heard of it before but I would definetly find the answer. How about the owner? |

I'm currently looking at a 1987 412, and noticed something very interesting on the service history of the car. Several times over the life of this car, it has had the motor mounts replaced. Is this a common problem with the 412? Seems odd that they would need to be replaced 3 seperate times!
I know they sit close to the exhaust headers, perhaps they are just located in a spot suseptable to extreme heat?
Thanks!
