A leak in the head gasket - often called a "blown head gasket" - can result in a leak of coolant, the combustion gasses, or both. Blue smoke from the exhaust suggests that excess oil is entering the combustion chambers (although there are other possible causes than a head gasket leak). White smoke from the exhaust suggests that coolant is ...
The exhaust diaphragm is exposed to the chamber pressure on one side, and exhaled gas pressure in the oro-nasal mask on the other side. This is a form of back-pressure regulator. The supply of gas for inhalation is through a demand valve which works on the same principles as a regular diving demand valve second stage.
A slow leak of the first stage valve known as intermediate pressure creep can cause the interstage pressure to rise until either the next breath is drawn, or the pressure exerts more force on the second stage valve than can be resisted by the spring, and the valve opens briefly, often with a popping sound, to relieve the pressure. the frequency ...
The cause of the problem was found to be one head bolt hole that was drilled too shallow at the factory, meaning the head bolt bottomed out and could never seal properly. In 1998, a thicker, multi-layer steel head gasket was introduced that eliminated this problem. General Specifications. Cylinder Configuration: In-line 4

Rusted out exhaust headers or lengthy periods of turning the starter can cause water to build up in the exhaust line to the point it back-flows through the exhaust manifold and fills the cylinders. [1] On turbocharged engines the intercooler is normally cooled by sea water; if this rusts through, water will be ingested by the engine.

The system usually consists of a tube, a one-way valve and a vacuum source (such as the inlet manifold). The unwanted gases, called "blow-by", are gases from the combustion chamber which have leaked past the piston rings. Early engines released these gases to the atmosphere simply by leaking them through the crankcase seals.
