Vauxhall Vectra Timing Belt
Ronald Douglas Murray
snapped due to a siezed water pump. Can anyone tell me if this
happens the valves always stay clear of the pistons avoiding damage.
I did not hear any noise, just the engine cut out. Thanks in advance.

existence and score out of ten for chance of getting away with cambelt
breakage. Mind you I did one on a Renault 1700 van and it hadn't damaged
anything.Could have been because it broke as attempt made to start the
engine, so it wasn't actually running under its own power at the time, -and
being commercial maybe it has a lower compression ratio.

True - quite a few cars have "non-interference" engines, ignoring old
cars with side-valve heads ;-)
However, I expect the Vectra will have some bent valves, as that's what
happens to Astras of that age. May not be too expensive to fix as you
only need to replace the affected valves and get a new head gasket. A
friend of mine repaired his own Astra for just over £100 in parts.

(also
the Ecotec unit) had the belt tensioner disintegrate when driving. It needed
new
pistons and several new valves as a result. However, it was doing about 3,500
RPM
at the time.
If the engine was just idling you MIGHT be lucky.

and pulleys/tensioners when you do it.

A relations son had a similar problem on a P or R reg 1.4.Corsa (32,000
miles).
He complained of a burning smell and took it to his dealer only to be told
they could not look at it that day.
Cambelt snapped the next day
Replacement water pump, cylinder head skimmed and all 16 valves needed to be
replaced, (15 bent, 1 "scratched").
900UKP in all
Possibly/probably a new camshaft in that price as well ?
The pistons were deemed OK but the oil consumption is still under
observation.

I rang Vauxhall Customer Care at Luton this morning. I asked the
question "If any of the valves are fully open will it collide with
the piston on the upstroke" a simple yes or no question. Their answer
was "it depends on what speed you were doing and other
technicalities". I asked them three times to refer it to their
Technical Support Team. A complete waste of time. So I rang a couple
of local engine rebuilding firms to check. Both said the piston would
definitely collide 10 out 10 times. At best I might escape with two
bent valves in the same cylinder, at worst - well you can imagine!!
So tonight I took the cylinder head of and..... I have two bent inlet
valves on the number four cylinder but no damage to the piston. I
just need to strip out the valves and guides and replace them, as
well as checking all the others.
In my searches on the Internet and all the advice I have been given,
a common theme that recurred was to replace the pulleys as they were
also prone to failing - something that I had not considered until now.
All in all, I suppose it could be worse. I expect the cost at dealers
prices to be:-
£50 for two valves
£10 for two guides
£40 for top end gasket set
----
£100
I have to class the £20 for the pump, £20 for the belt and £20 for
the pulleys as being routine maintenance as it was the seized pump
that caused the problem. I should have dealt with it as soon as it
leaked and replaced the belt and pulleys as part of its 80k service.
It has 81665 miles on the clock.
Thanks again to everyone who gave me advice and the benefit of their experience
Ron.

Ahh well, at least you now what the problem is. 2 bent valves isnt bad going
at all, I've seen all 16 bent, some lost their heads, a holed piston and a
shattered cam bearing shell on a car that was doing motorway speeds which
the driver coasted to a halt still in gear after it lost power. The engine
was totally scrap. He then needed a new cat as bits of valve / piston had
entered it and embedded themselves into the matrix. Not a cheap job.
Just make sure you change the tensioner / idlers for the non FP3 plastic
variety. The modded ones are all steel.
