Are you really sure about that? I'm sure he replaced the timing chain too. No timing belt/chain lasts forever. Timing chain lasts slightly longer than the timing belt counterparts, I think.
Did you read what guy say on his website. Home
REPLACED PARTS: 3 Fuel pumps, rebuilt alternator 3 times, 2 front springs and usual front end parts, 1 radiator in July of 2004 but still original hoses, turn signal unit, 2 windshields and normal tune up parts.
That all what he did.
Timing chain I have one on Ford 300 4.9L it have 300,000 miles it original. Rare they go bad but not often you see but with timing belt it too risk to try drive why timing belt break then you bye engine why valve hit pistons. That why I need replace timing belt on POS ISUZ geo storm and will sell to people.

Just confirmed.
