Best.

 

*shaking head sadly*


That's a pretty sad belt, alright..........

 

Is there a date code on the belts?

 

Doesn't look like a primary timing belt failure based on the pictures. Is it broken? Teeth just don't 'dissolve' like that. Those teeth look like they were scrapped off by in intimate contact with a non-moving part.

(opinion only--based on the picture posted)

 

it's a ferrari dude, they supposed to

but obvious, while you have the engine out, lots of things can be done much easier so just convince your costumer of the need of solving more little issues while your at it.

 

I had a similar problem a few years back but in my case the belt tensioner bearing seized up and burnt thru the belt. The ****ty part was that all service was being performed as per Ferraris schedule and the belts had been replaced 2 years previous along with all the other items required on a major service.

As you have discovered Yes you have to pull the head because you will have bent valves! And I would also recommend that while the motor is out you pull the other head and do the valve guides and seats on it or you will have a motor with great compression and sealing on one side and not quite so good on the other.

Also you should be aware that there is a special procedure for torqueing the heads, and be prepared for the possibility that some of the studs stretching past spec and not being able to achieve proper torque so you might want to consider replacing all of the head studs while you are at it. And yes I have been there.

Like Rifledriver the shop doing the work did a sloppy repair job, and the car never ran properly after. Five years and 800 miles latter I now have the car at an independent and after checking the car over we decided to pull the motor again, oil and antifreeze leaking everywhere.

Current tally is $10,000.00 in parts and no idea as to labor.

By the way I have owned my 86 328gts from new and always serviced it as scheduled in the manual.

Welcome to the world of Ferrari, not cheap!

 

Don't bother with Ferrari head studs. ARP are better and cheaper.

 

Aurora, no more news (and pictures) about this ?

 

if the engine was serviced right on reg. bases no engine should leak,I've had my 308 for nearly 2 years and some spots after 6 months of bringing her home due for a service last may and since still no leaks,but I do drive it alot to keep her lubed...she has 54k miles on the clock

 

To inform FChatters as well as help you inform this and future customers how to minimize the risk of a broken cam belt, please request that the owner answer a few questions and post his answers: 1) when was the last cam belt service; 2) were the cam belt tensioners replaced at that last cam belt service; 3) how frequently, such as times per month, did he drive his car; 4) how many ~miles did he drive on each occasion he drove(did he get the engine temp up to operating condition each of those times); 7) had he noticed any other than normal engine sounds lately; and 8) had he noticed any oil leaks or smell of burning oil lately. I'm sure others can think of other questions that answered would help minimize future broken cam belt(s)
