Mechanic shows off exhaust trick which tells | Tech News

A prime car mechanic has proven motorists how to inform if their vehicle is affected by severe harm by taking a look at smoke from their exhaust. Scotty Kilmer stated thick smoke coming from the back of a petrol and diesel car might signify a main head gasket failure. 

Other indicators embody foamy coolant and bubbles coming from the engine bay in a severe concern for street customers. The head gasket is a essential seal between the engine block and the cylinder head and stops oil, coolant and gases main out of the car. Leaving a head gasket failure might make issues with people at risk of overheating, loss of energy, and engine failure. 

Speaking on YouTube, Scotty stated: “Today I’m going to show you how you can tell if your car’s head gasket is as good as blown. 

“Now head gasket jobs are very expensive, itss not the valve cover gasket here on top. It’s in the middle where the head goes on the block, very expensive. Now you can buy a leak kit like I have. They only cost about 45 bucks but there’s easier ways.

“When the engine is cold take off the radiator cap and look inside, then start the cold engine and if you see bubbles coming out the head gasket’s blown. And if the coolant looks all foamy like a milkshake then head gaskets blowing.

“If you see a bunch of white smoke coming out from the tailpipe that means coolant is getting into your exhaust system and it’s not supposed to do that. So if you’re buying a used car and a head gasket’s blown, don’t buy it.”

A blown head gasket might set motorists back round £700 to restore however changing elements on higher-end luxurious fashions equivalent to SUVs might price more. 

Experts have weaned street customers might finish up paying virtually £1,850 for new elements in a blow to cash-strapped street customers. 

Motorists took to YouTube to reward Scotty with some suggesting head gasket failures could also be more common than many may consider.

@michaeltipton5500 stated: “I’ve seen people driving down the street with clouds of white smoke coming out.  I immediately knew this.

@raysoucie489 added: “Years ago, I mistakenly bought a Subaru with a blown head gasket.”

However, one driver appropriately harassed that not all white steam is poisonous and a trigger for concern.

@ThatLow_Slow5.3 added: “Hear me out Scotty there’s also hydrocarbons in the exhaust that create white smoke like that  on cold start but it’s not obnoxious smoke.”
