Re: Fast warming engine?

The mushroom shaped object is the oil filler cap. It also contains an air filter. Air is supposed to go into this filter, through the engine, and exit by a pipe at the back of the engine called a road draft tube.

It is not supposed to smoke, however when an engine gets worn pressure can blow past the pistons, pressurizing the crankcase and causing this smoking. It is called blowby.

This is nothing to worry about unless it grows excessive. If the engine has been out of service for several years a little blowby on first starting is normal.

When driving down the road, the fumes escape under the car.

Your car should have either a 160 degree (winter) or 180 degree (summer) thermostat. This means, 150 degrees isn't even warmed up.

I suspect your thermostat is missing or stuck open. Normal operating temp with a 180 thermostat would be 180 - 200 degrees, possibly rising to 210 or 220 on a hard uphill pull on a hot day, or when idling in traffic on a hot day. With a good 7 pound radiator cap this is no problem.

There are products like "Rislone" or "Bardahl" that might help the oil burning problem. I don't know if these products are sold in Europe, but there should be an equivalent. Look for a thin substance that says "frees sticky lifters" or "frees stuck piston rings" on the label. Do not use the thick ones like STP at this time.

It is possible your engine has not even warmed up yet. On a big car like that it can take 5 to 10 miles to fully warm up, and 50 miles to get into its stride.

The symptoms you describe are nothing to worry about. I would add the Rislone and try a longer trip, such as 80 to 100 KM at speeds up to 90 to 100 KM Hr.
