Each standard piston/crankshaft automobile made today has an engine block and a cylinder head which attaches on top and between these components is the eminent head gasket. You may think its nothing but an ordinary seal of the combustion chambers, the coolant and oil passages but mind you, the purpose of the head gasket is not as simple as you think. The head gasket is the most crucial seal in the automotive engine. Read on.
The function of the head gasket is to seal both the compression of the cylinders and the coolant flowing between the block and the head. It has to provide a leak-free seal from the moment it was installed and uphold that seal for the life of the engine – which might well be 150, 00 miles or more on a lot of today’s automobiles.
Most car owners do not consider a head gasket replacement or most people think that a blown head gasket will never cause a problem. But they are wrong. Blown head gaskets would surely leak and leaks can pose much threat on the over-all safety of the car and the occupants as well. If truth be told, it is one of the most common factors of explosion that has taken precious and innocent lives.
How can you determine if you have a blown head gasket? It is not usual to find a bad or blown head gasket on newer car models, but through time, it’ll happen. If your vehicle has overheated and has not run well lately, it may be because your Lexus head gasket is bad. Even if current gasket technology drastically reduces gasket wear, sooner or later, your Lexus head gasket will wear down.
There are other signs of a bad Lexus head gasket and these include a constant increase in the consumption of coolant, a milky accumulation found below the engine oil cap after extensive engine runs at operating temperature, a very apparent thickening of the crankcase oil, and gas bubbles going out through the radiator cap. If you are experiencing these kinds of culprits, your Lexus head gasket really calls for a replacement.
