I know im kind of a noob for asking this but, our engines aren't belt driven right? I didn't think they were even chain driven. Dont we have cam gears instead of a chain or a belt? Thanx for all your input guys.

SPI's and Zetecs use timing belts if that's what you're asking...


DURATECS HAVE TIMING CHAINS! BWAHAHAHAHAHAHA! HEY LOOK! THIS IS IN SONIC BLUE! BWAHAHAHHAHAHA!

BRED FOR PERFORMANCE! Well seeing how it's a tuned up Zetec, it should still use a timing belt.

Aww nuts...I thought they were more hardcore. How often do you think our belt needs to be replaced?

^^^ According to my Service Guide that came with the car...not till 120,000 miles.
I'd probably do it sooner than that though, around 75,000 miles. [;)]

The 120,000 suggestion is in the standard guide and refers to the regular Zetec which is not an interference motor.

The SVT is an interference motor so if the belt lets go bad things happen.

Doug is correct, between 60k to 80k miles on the svt. What does the "i thought they were more hardcore" mean? I dont get that one.

more hardcore as in having a chain which never needs replacing. Get it?

Wholley hell!! That does NOT look good! ..... As a rule-of-thumb, I have always been advised to change the timing belt every 60K miles ..... think I will stick with that policy. LOL

a belt is actually more'hard core' than a chain. Take a look at all your old school V-8 engine builders, they all seem to be switching to a belt driven cam or gear drive.

A belt has very little stretch, and nowadays most have automatic tensoiners, where a chain ends up with a lot of slack over time, and usually just has a plastic guard that doesn't really help all that much once it gets grooved up.

I'll take a belt I can change easily, and also easily install a method to chenge cam timing versus a chain that I have to pull half the motor apart to change.

I think Zetecs have belts. I'm positively certain that Duratecs have CHAINS. Belts are cheaper and quieter, but chains don't stretch or break - hardly ever.

You see cam gears only in pushrod engines, not in OHCs like just about every modern four-cylinder motor. The last fours I saw with timing gears were the GM "Iron Duke," used in the awful X-Body front-drivers (Chevy Citation, Pontiac 3000, etc.) and the Pontiac Fiero, GM's excuse for a mid-engined sports car, and the Renault R-5s and R-9s (LeCar and Alliance, respectively, in the USA).

From a V-8 builder and performance enthusiast.... (me)

I don't think so!
