timing belts are crap

I would also think the labour replacing a timing chain would be higher.[/QUOTE]

If you want to replace a timing chain in a Kent Crossflow in a Mk1 or Mk2 Escort, either the engine comes out or the front crossmember comes off (along with the steering) as the sump has to come off the engine to get the timing chain cover off.

My one now has a double chain with wide tensioner to take the rev's. It was rebuilt with a custom cam and a big valve unleaded head.

We had a 96 Micra that had a chain and when we got rid of the car, it had 160K miles on the clock with it's original chain. I now hear that the car has 200K plus and still going strong.

The only thing I have with a belt is a Citroen AX GT and it's due another timing belt :mad:(5 years). All my other cars have chains, and I'd take them any time.

There is no timing chain in a push rod engine. http://en.wikipedia.org/wiki/Overhead_valve

What about the good Kent Crossflow? A pushrod engine with a timing chain

The rattling noise from those Ford pushrod engines would put me off buying one . OHC is so much quieter.

The rattle is from the rocker gear and is due to valve clearances tightening. Get the valve clearances checked & adjusted and it's gone.

It's a simple maintenance matter.

At this stage, you can guess that I like the good ol' Kent Crossflow.

I was correct already on that one, Im more familiar with heavier plant and marine diesel engines and not the micky mouse stuff one would find in cars.

And it's not just a mileage thing - belt's life is expressed as mileage (for simplicity) or AGE. Rubber perishes. That low-mileage, pristine, garaged car, is just as, if not more likely, to break a belt than a well used one........

Indeed! My car has only done 5k miles since the last change, but that was nearly 5 years ago. Nearly time for another change (depending on the inspection by a specialist)

Thought the cam followers/rockers would wear quicker than the valves/seats causing the the valve clearances to open , thus causing the rattling.
Run to the hills - its rumored that w.o.b used his own hot air to inflate that inflatable.
