There's a white smoke coming from my exhaust does this mean my head gasket's gone? It's a Renault Clio

Answer 1

If the head gasket goes the smoke will be black, i.e. you're burning oil. White smoke, particularly on coldish days, is probably nothing to worry about, your choke is on. If the smoke persists even when the engine is warm then take the car in for a tune and service.

Answer 2

There is a basic test to find out. Napa sells a cylinder head tester/block tester.
It is a chemical test. Basically you will remove the radiator cap while the engine is cold, then bring the engine up to temperature (follow instructions in the kit) and test with the chemical. If it turns green, it's blown. Before you do that, if the gasket is really bad, the engine oil will be white and milky. Check the oil first. The last time I bought a kit it was around $70.00. It will cost that much to take it to a mechanic.

Answer 3

Oil leaks create blue smoke, not white smoke. It replace into plausible there replace into nevertheless some water in the engine and the white smoke/steam will bypass away after it warms up.

Answer 4

When your head gasket goes you tend to lose a lot of water from your header tank. There will also be a white emulsion/gunge inside your rocker box lid cap where you fill up with oil. This is the water mixing with the oil.

Answer 5

If the smoke smells sweet, its antifreeze getting into the combustion chamber, possibly through a cracked gasket. If it's automatic and smells oily, it's a transmission modulator. Still not sure, do a compression test.
