    My 77' 308 GTB is "due" for a belt change. The last change was 5 years ago and 3,000 miles. The car starts, runs and drives like it is new and does not leak one drop of oil!! I am afraid to bring it in for a major (with all new seals and gaskets) since it is running so well and leaking nothing. I understand that the (if it ain't broke don't fix it) rule does not apply particularly well too Ferraris, but isn't there a happy medium between the two with just some light preventative maintenance and a belt change only??

    ...and not because I sell the parts.... but, I would probably do the belts and bearings.

    Sorry, I would of course do bearings.

    Yes you can but I would at least do the coolant, oil & filter, gearbox oil and fuel filter. Plus you have to take off the access. belts to change the t-belts anyway so you might as well replace them.

    Its your car & your money, you can do as much or as little as you want, although as has already been said you need to do the tensioners at the same time as the belts.

    When was the last time the valve clearances were checked? That would be the only other major thing to consider & that might lead to replacing camshaft oil seals on the basis that "you might as well while yr in there".

    Accesory belts, timing belts, tensioners. That's all you need to do. You have to drain the coolant to get the belts off so you'll have to do that regardless.

    "Accesory belts, timing belts, tensioners. That's all you need to do. You have to drain the coolant to get the belts off so you'll have to do that regardless."

    Is there a step by step guide for the DIY'er out there to be seen or purchased?

    Why do you have to drain the coolant to get the belts off?

    Have you ever had anyone report rust pits on their bearings? Mine seem to have some small ones on the outer race outside of where the belt itself contacts the bearings.

    Note: I did not buy them from you but from another well know supplier.

    Because you have to move the aluminum coolant hose that is on the front side of the engine out of the way to get the belt covers off. You can NOT drain the coolant and have a nice mess on you garage floor but that's your decision.

    WHOA! No, I have not heard that. You're referring to the SKF ones, right?

    If the suppliers don't leave them in the SKF anti-corrosion paper, I suppose that's possible. My inventory is stored in a humidity controlled environment. I'll go check a few.

    My Hill Engineering bearings are wrapped in about 600 layers of plastic, from London. And sadly, they have a shelf-life at Ricambi of about 62 nanoseconds. Literally, I cannot keep enough in stock... it's incredible.

    Yes, they are the SKF bearings. They were fine when I put them on the car 2-years ago, but when I was rebuilding my carbs I looked down onto them and notices some small rust spots on the surface (or what looked like it). It was ONLY on the area not touched by the belt. The rest of the surface looked fine.

    You'll have the timing belt covers (and valve covers) off anyway...there's so much that can be done while you are in there, you might as well change all of the belts, gaskets, change your fluids, etc. The tensioner bearings are only a few minutes more. Do them.
