The cinqs are hydralic tappets, peope have gotten good result from using the uno 903 rocket arm and gear and their tappets (gap are manuallay adjusted).

May be give that a try ~ if you got the parts

Or clean and reset the hydraulics ones.

Most motor factors will sell a hydrulic tappet bottle of magic liquid, to dissolve the gum, that may be causing the problem.

Add to oil, run engine for a frew minutes stop have cup of tea and run engine again, if it is not quiet after that you have a dismantle problem, dont use a whole bottle... save half for next year.

You are probably not changing the oil frequently enough for the usage of the car, like if you leave it unused for intervals you need to change the oil more frequently. little cinq is speaking to you tick tick tick...

Also get a bottle of the fuel injector cleaner e.g. Redex, this saves petrol and possible engine damage use less than recommended.

A sumpful of derv will do the same job.

Follow the instructions and don't load the engine.

Hi David
The stuff I used was supposedly ok to leave in the oil, but I had to change the oil any way so I did not find out. The car had not been used for six months while I fixed an engine and a suspension problems, so the gum was not unexpected.
It was not that expensive.

You can after you retro-fit the old Panda/Uno 903 solid rocker assembly.

There is no preload adjustment on Sei tappets, only on Cinq ones.

If the Diesel flush doesn't work, (I've never tried it myself) remove the throttle body and rocker cover, remove the rocker shaft, taking care to undo all the bolts a bit at a time so as not to bend the shaft.

On a sei the tappets pull out of the bottom, wheras on a cinq they come out of the top and are retained by a clip.

Pull them all out, and leave to soak in engine degreaser overnight (or coke)
then get them all freed up nicely and the pistons working smoothly.

Any that don't spring back and extend as far as the others pull apart and check the spring at the bottom, if it's broken - replace the tappet. (£8)

otherwise re-assemble after checking that all the tappet plates (little coins) are in the rightway round and are not worn.

Reassemble, using a new rocker cover gasket if needed and away you go.

I did this to a Sei I bought that turned out to have one damaged tappet and it sounded like a tractor prior to doing it and like new afterwards.

Chances are if it's just a bit tappetty and not too loud the then you've not got broken springs.

Cinq has the disadvantahe of needing the preload adjustment set (not sure about late model Cinqs may use the Sei setup) but the advantage that you can buy a whole set of new tappetts from ebay for under £30

I have yet to fit mine.

The Sei have two types of rockers.
Early Sei have the same as Cinqs. ie hydraulic+adjuster
Late Sei have different rockers with only hydraulic, no adjuster.

I stand corrected, I always assumed the change occurred around late Cinq era, as I had a 2000 Sei with the later type, now I know.

Incidentally I looked into the solid setup, the biggest disadvantage I could find was locating a panda or uno rocker assembly.

Do you happen to know whether all three types are interchangeable or can you only fit a solid setup to the earlier type?

You are correct.
It was a change in the late Cinqs, not in early Sei.

I need to get more sleap...! :spin:
