►A blown head gasket is one of those commonly mentioned terms you'll run into over the years, whether you're interested in cars or not. It's something you will hopefully never have to experience, but you should know what it means and how it happens just in case.
To put it simply, a blown head gasket is when the gasket that secures the cylinder head to the engine block has failed. Coolant, oil, or combustion gasses from the cylinder can then leak out through the failed gasket. The consequences of this can range from a visible leak of oil or coolant to a noticeable reduction in performance and driveability.
Watch episode 2 of Automotive Slangs Explained to dive deeper into the topic of a blown head gasket and to see what this looks like as it happens inside your engine.

Bro, you literally anticipated every question I had and then answered each one so clearly even I could understand, with my severely limited mechanical knowledge. Thank you very much for making this absolute gem of a video!

@fcpeuro Год назад

Happy to hear it And! We hope more people can find these videos helpful, appreciate you giving it a watch.

You spelled “what is a Subaru” wrong in the title

Poor subie owners - as if the shots in the video weren't harsh enough 😁

The video does a great job of explaining the various ways that a head gasket can fail and cause problems. In this day and age of automotive technology it may be more appropriate to say that a head gasket is "damaged" rather than blown due to the fact that many cars are being driven with damaged gaskets with chronic symptoms whereas a car with a "blown" gasket will generally have acute symptoms which severely prevent the use of the vehicle. Keep rolling....

@fcpeuro Год назад

Very good point Junkyarddawg - as you mentioned, technology advances have made the "failures" not as drastic as they perhaps once were, often times leading to people driving much longer than they really should. Good insight

Im a bit of a dummy when it comes to automotive. I found this as yesterday a guy was in a parking lot with his hood up next to the gas station i was stopping at. Thick blue smoke pumping out the tail pipe, and some out under the hood. When he was finally pulling away, he was crawling while blue smoke poured out. An old man told me he had a blown head gasket. Thank you for making a simple, easy to understand, video that allows me to understand all that. I like trying to be more of a handyman, and youtubers like you can at least give me the ability to understand. Thank you!

Wow you explained that perfectly All the right details, at the right time in a comprehensive way There are so many crappy videos on YT--- where things are either too simplified lacking detail, or too much detail

Blew two head gaskets on my S-10 as a kid. Both times, after a coolant drain/change. Back in the day it was yellow and didn't last 100k miles. Remember to let the coolant circulate before driving and watch the temp gauge like a hawk if you change it. 1st time I didn't put 2 and 2 together, sure did after the second.

@mikikum1 Год назад

An awesome video! 👌 Btw I thought that only wbite smoke imdicates the blown gasket whereas the blue one means a broken piston ring but I seem to have been wrong?

@jameslila2254 10 месяцев назад

My old 1990 Celica is beat up with all bald tires and all the warning lights on. When I drive it's sluggish with white smoke coming out the exhaust. Engine is always hot on the temperature gage indicator.

Here is my boy. Driving on the highway, pop the hood, found out coolant level low, OPEN THE RADIATOR CAP and top off with water.

@thomasanderson1416 Год назад

For oil and coolant maybe making their respective circuits separate between top and bottom and alleviate the problem a bit.

@Livingandcooking Год назад

Batter to have head gasket replaced, or replace engine?

@fcpeuro Год назад

Replace the headgasket as long as no internal damage has happened. MUCH MUCH cheaper and usually easier!

@Livingandcooking Год назад

Ok thank you

Blew a head gasket on a 1984 Mercury Capri 4cyl which was a mustang knock off. Happened a few days after I shifted from 5th to 1st by accident going down a hill beating a yellow light in Poughkeepsie. Totally missed 3rd gear.

@fcpeuro Год назад

Wow so technically you achieved Episode 1 and 2 of this series! Now the question is have you smoked a clutch? Thats next weeks topic 😂

@paperandmedals8316 Год назад

@@fcpeuro never smoked a clutch. I’m an adult now and my BMW’s and Mercedes have not suffered the abuse and fate of my teen years’ vehicles.

@FordTransitvan 2 месяца назад

Thanks for this, great explanation for a moron like me

@thomasanderson1416 Год назад

Could be nice to get back even more to the basics. Why should there be two parts for the engine? block and head. Why not just make one block? And why does there have to be a 3rd gasket between them, why not seal them somehow without it. Thanks. EDIT: Oh never mind, you answered it, ur da best dude!
