zetec blacktop timing out??
Hi
If the timing was out on the cam pulley by one tooth or so what would be the symptoms. As my engine is out I am going to replace the timing belt. I
have the cam and crank locking tools. I have not taken the old belt off yet but noticed once the crank was locked at TDC the cams were out of line for
the locking bar to fit.
This is where I left as time ran out.
So it appears the timing is out so would this be noticeable? The car seemed to run fine. (albeit it not particularly fast considering these things are
meant to be pretty quick)
What would the possible signs be??
Ta
Andy

Have you checked that the engine is actually at TDC. You really need to check the accuracy of the crank locking tool before drawing any conclusion
about the cam timing.
Do not rely on the crank or cam locking tools to hold the components in place should you need to actually loosen bolts. You will potentially cause
lots of expensive damage if you do.
On a standard engine one tooth would probably be unnoticeable but when set correctly you will obviously get the best performance/economy combination.

We had a customer with a Sigma engined Fiesta. It was sluggish (down right slow) even for a 1.25 and had been from new. She'd had it back to the
dealer several times to complain about the performance before she ever came to us; When we questioned the performance she insisted "Thats how
they are. Ford told me so" and didn't want us to look at it.
Then, at 10 years old, we changed the cam belt. Exhaust cam was one tooth out. Turns out it was actually a 1.6 and a flying machine. She nearly went
through the doctors surgery wall opposite when she collected it as it launched!

As already suggested double check TDC although I doubt it will be out and DO NOT use the cam locking bar when undoing the cam sprocket
bolts,I've seen cams broken that way . Make, borrow or even buy the correct tool. The crank pulley bolt should be tight, a decent air wrench
should shift it , fit a new bolt IIRC 2 are supplied with a cam belt kit, measure the depth of the crank drilling also not a bad idea to replace the
cam sprocket bolts which don't tend to be supplied.
