Yep, that's the one. Must point out though, we NEVER do this unless the
owner is there and gives their permission.

thanks for the replies so far.

decided to cancel the garage and new injectors. reading through i think
there are two main reasons why it failed, the first is my driving if i say i
drive for more mpg rather than speed, i change gears asap keep the revs low
and keep the speed at 55 mph and below (i get 32 mpg). i work about 3 miles
away so its short journeys mainly. the second is i don't think the engine
was warm enough when the test was carried out, the test station is 2 miles
away and i was told to take it about a 2 mile drive before the emissions
test.

plan of action-

i have got a bottle of wynn's injector cleaner and i am going to blow the
cob webs of the engine over the weekend, leaving it till 3000 rpm and over
between gear changes then when i take it back for a retest i will take it on
the motorway to get it nice and warm and give it a little thrashing. if that
does not work then i guess it is new injectors after all.

question about the injector cleaner, it says put it in the tank but the tank
is 3/4 full so it will dilute quite allot. is it ok to put it in the fuel
filter neat?

The STP bottle reckons a tank is 50-60 litres, and the Wynn's the same -
personaly I'd chuck the lot in with 3/4 of tank - but you could do it
pro-rata if you liked.

And there's no provision to use a clamp to fasten the probe to the
dipstick ?

The probe and dipstick together will not fit into the hole that is intended
solely for the dipstick!

If you know the cambelt has been done at the correct interval then I'd
be redlining it between gears. You'll be shocked at the amount of
rubbish coming out the back.

South West electro-diesel, in Carmarthen. Bit difficult to find, now,
they've moved. But they're in Johnstown, and also the phone book.

I thought it was more about the risk of engine damage involved in thrashing
the nuts off it when cold.

the original test, as you doubltess recall, involved running it at maximum
governed RPM for 10 seconds. They blew up a few engines which were past
their first flush of youth, then they changed the test...

I've developed a habit, having warmed the engine up fully, of doing me own
version of the smoke test on the approach to the garage - check for nothing
behind, drop into neutral, floor throttle for 2-3 seconds, let it idle and
repeat. This blows out the first lot of soot from the engine before they
get to test it :)

that's why I said make sure the temp gauge shows hot
Only ever had one that showed signs of "distress" and that was
a skoda 7.00 on the first acceleration 9.99 on the second and a
loud clattery noise I stopped there it still ran and sounded ok just
didn't want to push my luck

On an (extremely!) similar note - does anybody know of/recommend a
diesel specialist in the Rochdale/Greater Manchester area?

Mine's taking to blowing more and more black smoke along with a massive
increase in fuel consumption - Now, part of that's going to be the
crack in the exhaust manifold not letting the turbo come up to speed,
but I doubt that's all of it.

Went poking around yesterday and found the plastic tray that runs along
the bottom between the radiator/intercooler and grille had been bent up
more or less blocking the intercooler and bent it back, but is a
blocked intercooler likely to cause the smoke and increase in fuel
consumption?

Hi-Tec Diesel in Bury.
Bury Diesel Centre in.....

Hi-Tec have everything but can be pricey. Also not terribly good on
technical details when I had serious problems with the family Scenic
Diesel. BDC are very friendly and helpful, and tested my 200
Tdi'injectors for free when I took my dad's Saxo in for a tuneup.

More of a general mechanic than a diesel specialist AFAICT, but damn
handy for getting a 205/16 innertube from at 5:25 at night when no
other place in town carries them (The young lads at National Tyres had
never seen one before!! - My disco's got Rangie Rostyles on it and so
can't use tubeless fitting)

He managed to sort the huge f-off Mazda lump in Grahams 101.

Steve's very good, and knows everything about 101's - he was a member in
single figures wasn't he ? I nearly bought his 101 before we got Bob,
but with 4 XZL's on it, it was too much.

He's got just about every issue of SixStud ever in the waiting area -
alongside every Military vehicles magazine I've ever heard of - judging
just by his magazine collection I get the feeling his first love may be
military kit with Landies being a sideline simply because the army use
them.

Really? Which bit of the engine? Is that why petrol engines don't last as
long as diesels? :))
