One idea to the posting earlier as reproduced below said
" I had the same problem a few weeks ago so I took it into a garage and he
told me it was a sticky valve and he would do it for £165.00 + VAT. not
having the cash on me I said I would come back (yeah right) ! I flushed the
oil then put in some magnetech oil and filter and guess what ? no more
tapping and saved myself around £165 "

Gotta 1989 G reg 440 with 1.7 manual petrol engine. The old lady starts fine
and runs well. When starting a journey there is often a clicking sound
coming from the engine bay. It is a rapidly repeated and irregular clicking
sound, rather metallic. It isn't always there at the start of a journey and
lasts only a minute or so. It happens when the car is moving, still or in
neutral BUT only when the engine is cold. It really is one of those
irregular sounds as it can't be guaranteed to happen every time the engine
is cold!!!!
Methinks that it sound like a relay but seems to be coming from the middle
of the engine bay rather than the right hand side where the relays and fuses
are. The indicators and wipers work o.k.

Any ideas will be appreciated. I have tried running the engine and leaping
out of the car and opening the bonnet to locate the source of the clicking
but fid it difficult to identify where it is coming from. Could it be a
death watch Beetle sending a Morse code message to the scrapyard????



Does this make sense please folks? Seems easy to do to stop the metallic
tapping that occurs at odd times.

Sounds like a tappet or valve rocker a bit short on oil pressure till the
engine warms up a bit.
Normally nothing to worry about.

An easy way to find out : change your oil and filter and see what happens.

Switching to another grade may stop the ticking...

And make sure the filter has a non-return valve.

Mine has, which means when the engine's off, oil will stay in the top end
of the engine.

My brothers car doesn't (900cc FIRE Cinquicento - they stuck hydraulic
tappets on the rattly old 903 engine! Can't believe it), and it rattles
until the oil's flowing properly.

And moved the camshaft as well. :)

Did they?

Oh. It _looks_ the same as the old one (externally).

Are you sure you're not referring to the 1108cc FIRE engine? The 899cc
(that he has) is a _slight_ modification of the Italian 903cc, which is
descended from the old 903cc 45bhp engine they fitted in everything (Uno,
127, Yugo etc).

I'm _sure_ it's still an overhead valve though, but they've modified the
rocker gear with basic hydraulic tappets to shut the engine up.

I'm also pretty sure it says it's a FIRE engine, but most places only
mention the 1.1 as being FIRE.

I've done a bit of rooting around, and found the page below. I actually
googled, and found someone with a maxxed out Cinq. He'd fitted silicon
hoses to a 1.3 Fiat engine, put a Seat ???? Cupra turbo front splitter,
and half the car was primer grey.

I then found this one.

That is some _seriously_ illegal tint on the front side and front
windscreen there.

OHC FIRE engines (have a cam belt): 763cc, 768cc, 999cc, 1108cc.
That engine's so common I know the part numbers for service parts better
than I do MkIII Fiestas... PH4558 CA4556 BCPR6ES...
OHV engines (have a cam chain): 704cc, 899cc, 903cc & 1116cc.
 
Valves gear is very good on these cars, similar design to 360/240 engine
with buckets and mechanical linkage, very simple and reliable. Any
mechanical noises iindicate a more fundamental problem, unless it is an
unusual electrical problem, which is quite possible on this age of car.

Suspect warped head, replace with skimmed scrap unit, new gaskets etc. Use
a Volvo specialist if possible otherwise get rid of it.

The 900cc Cinq has the old OHV engine, not the FIRE lump. FIRE is only
made in 1.1 and 1.2 capacities.
