Smoking Engine!

[Vixster]

I have a xsara picasso 2001 1.8 petrol. It's smoking from the engine but only noticeable when I lift the bonnet. It's coming from around the dipstick area and from another part of the engine opposite.

 

I checked the oil a couple of days ago (needs topping up regularly) and I noticed a white substance on the end of the dipstick. Checked it again earlier today and it seemed clear.

 

I'm wondering if the head gasket is on the way out? It smells fumey when left running idle and when doing slow manoeuvres. It also smells rather hot after a short 10 minute journey, although no indications have come up on the dashboard saying that it is overheating.

 

I am no expert in cars so please if anyone replies speak in laymans terms!

I suspect you're correct on it being the HG. A garage can do a "sniff test" (checking for exhaust gases in coolant I believe) which should help pinpoint it.

Welcome to the forum.

 

It may not be a head gasket failure and could be just a cam cover gasket or a hose leak allowing oil to run down the engine and the mayonnaise on the end of the dipstick (and possibly oil filler cap) may be due to the engine not getting hot enough due to short journeys or the thermostat failing open. Or possibly a fuel injector seal leak giving fumes or maybe an exhaust leak. Or maybe a coolant leak from a hose/gasket/water pump or core plug. Obviously it is difficult to tell without seeing the car.

 

If it is using oil, are there any signs of oil leaks down the engine and any oil drips on the floor ?

Does the exhaust give any smoke on start up, when driving on accelerating or when the accelerator pedal is relased to indicate if the oil is being burnt due to piston rings wear or valve seals wear ?

How much oil do you add and over how many miles ?

Is the coolant level rising or falling and are there signs of oil in the coolant expansion tank ?

Are there any light coloured stains down the engine left by a coolant leak as it dries ?

Is the car used on mainly short journeys which do not let the engine warm up enough ?

Is the cabin heater still giving hot air ?

Are there any unusual noises from around the engine such as a chuffing noise ?

Does the car still perform normally ?
