Thread: Clio I: Engine smokes

I've just bought a clio 1 1.2 40kwbauj. 93, 170.000km auctioned, had been one year.

Really onlyneeded for my other valves Clio (, timing belt was cracked), (sametype), but a whole car become. Unfortunately running with the enginenot really know air filters, candles, water cooler, already swapped.

one spark plug combustion has rust-brown, the other 3 candlesand wet oily. Sparks same for all present. Unfortunately has nomodifications, no longer Au, otherwise I would hit him once on theroad.

what could it be?

Because of the wet candles might be a compression test give information.

Your blue smoke is Motorola, which is burned. This may be due to the valve stem seals, would be rather inconvenient in a crack head or broken oil control rings.

Today I had tested.1 compression, 2.4. Cylinder 10 on the scale, zyl.3 7 on the scale.

Did then removed the cylinder head, Außlassventil 2 and 3 have black hard russenments back, the pistons have mentioned the same thing. What cause?

How do I get the valves when they are not as crooked (it must still develop, control) clean again?

or what should I do next? I note for everyone.

The cause is probably clear the burned engine oil. If you give oil to the piston engine, it then runs away to bottom, or does it stand in the combustion chamber?

When it stops, the valve stem seals on the affected cylinders are probably over.

The soot can soak it (gasoline or brake cleaner) and then gently scrape off. Do not scratch with heavy tools, that use a metal tool! Wooden wedges are better suited or soft plastics.

Unfortunately, the oil has run on the piston -2,3,4. Cylinder down
not a good thing as you already suspect.

will not repair it, maybe I'll get something as spare part donors.

Thank you first for your help.
