take it slow engine are different we are showing you how we do it
any questions you have message me and i will be glad to answer as many as i can
A head gasket is a gasket that sits between the engine block and cylinder head(s) in an internal combustion engine.
Its purpose is to seal the cylinders to ensure maximum compression and avoid leakage of coolant or engine oil into the cylinders; as such, it is the most critical sealing application in any engine, and, as part of the combustion chamber, it shares the same strength requirements as other combustion chamber components
MLS or Multiple Layers Steel -- Most modern head engines are produced with MLS gaskets. These typically consist of three layers of steel. The contact faces are usually coated with a rubber-like coating such as Viton that adheres to the cylinder block and cylinder head while the thicker center layer is left bare.
Solid copper -- a solid sheet of copper, and typically requires special machining called 'o-ringing' that places a piece of wire around the circumference of the cylinder to bite into the copper. When this is performed copper gaskets are extremely durable. Recently companies have started producing copper gaskets with integral sealing wires permitting their retrofit into engines without the removal of the engine block for machine work.
Composite -- an older technology. Typically these are made from asbestos or graphite but are more prone to blowouts than newer gaskets. Asbestos gaskets are becoming increasingly rare due to health concerns.[2]
Elastomeric -- a gasket type used by Rover on their K Series engines. It utilised a steel core plate with molded in place silicone rubber beads to seal oil and coolant passages. The bores were sealed by rolled steel fire rings in a more conventional manner. The idea behind the gasket design was to produce a production version of the technology used in F1 engines at the time. The original application of the gasket on the smaller versions of the K Series was very successful. However, an engine redesign resulted in persistent problems with the design -- the joint interface became unstable and the gasket could not cope.
The cost of a replacement gasket is usually not extreme, but the price of total repair is significantly high. This is because removing/replacing an engine head is very time consuming - around 75% of cost will be labor. Furthermore, untreated blown gaskets usually seriously damage the engine, then requiring even more expensive work.
a lot of engines have a certain amount of mayo in the rocker boxes ,this is due to short runs ,not head gasket failure
Just check your oil, If the water is mixed with the oil your head gasket is gone.
Not always. You can have problems arising, and the CO2 Combustion tester will pick up the early stages.
@paul lowe exactly right mayo isnt a unique sign and it can also point to a stuck thermostat. When the engine never gets warm in winter the oil collects a lot of condensation water.
nice snif tester
nice vid
love that enging so basic
Hi there, great video, very informative! :-) I have a 06 reg Vauxhall Corsa C, it is the LIFE model and it only has the 998cc 3 cylinder engine in it. It has only done 92,000 miles! I think the head gasket has gone. It is mis-firing, difficult to start, and when running only runs on two cylinders, barely idles at all! It is belching out white smoke/steam, smells horrible! The engine coolant disappears after less than 10 miles of driving, the whole lot just vanishes. Here's the funny thing though, the oil is fine, still nice and black, no white bits, just a tiny bit on condensation on the oil cap. So, if the water is disappearing, and the oil is fine, where's the water going? Straight out the exhaust? I have had to stop using it now as there is no power, it'll only do about 20-25mph in second gear with the accellorator pedal to the floor! lol I am also worried I might get pulled over as there is a lot of smoke coming out the exaust, everyone disappears in fog behind me when I pull away! Doesn't sound good to me! :-( But, why have I not got mayonnaise in the oil? The engine coolant must be going somewhere? Warm Regards, Adam Ellender.
I have a Astra f '95 1.6, basically the same engine as the one shown above.You said one of the symptoms of a blown gasket is the white smoke and the water dripping from the exhaust.That got me a bit worried, because 1,5 years ago I had that gasket changed but by cold start this white smoke is always there along with a lot of water dripping from the exhaust.However my car runs on autogas(LPG), not gasoline and i was told that this is normal for a vehicle running on LPG.I don,t have the mayonese and the water pressure is normal,would you recommend changing the gasket again?
It may just be steam from the hitnair hitting the cold air in the first start
Failed oil cooler can also cause this
97! flip-in-heck, that brings back memories.
Another thing lets say one was color blind, what color would the liquid be? ;-)
It would look like thick old milk!
How to test for HG failure. 1). Has it got a Rover K series? If yes HG has Failed!!
lol
Engine sounds just like my corsa which seems to be running ok to me...... :/
know not no
lol
