Core plugs can also sometimes prevent freeze damage to the motor. During the early stages of the freezing of the engine coolant a freeze plug will sometimes burst, and thus allow the coolant to exit the engine, before it might expand within the engine during the freezing process and potentially crack the engine block.

In an internal combustion engine, a head gasket provides the seal between the engine block and cylinder head(s). Its purpose is to seal the combustion gases within the cylinders and to avoid coolant or engine oil leaking into the cylinders. [1] Leaks in the head gasket can cause poor engine running and/or overheating.
Engine seals will leak a small amount of oil as a function of the seal design. This is known as the permissible oil leak rate. [ 11 ] If a bearing seal fails and begins to leak, depending on the location of the seal, a higher amount of engine oil may be released into the compressed air stream.
On February 8, 2009, Toyota announced a recall of approximately 7,300 early 2010 model year 4-cylinder Camrys due to the possibility of the power steering hose rubbing into the front brake line which may cause a brake fluid leak. [102] On February 3, 2010, Toyota recalled approximately 153,000 vehicles from model years 2005 to 2011 for failing ...
2. They Could Use Cheap Oil. Some unscrupulous mechanics might use lower quality oil while charging you for premium brands, affecting your engine's longevity and efficiency. The problem isn’t ...
Particles in the oil can also cause serious problems with oil pressure. After oil flows through the engine, it returns to the oil pan, and can carry along a lot of debris. The debris can cause problems with the oil pickup screen and the oil pump itself. The holes in the oil pickup screen measure about 0.04 square inches (0.26 cm 2). [6]
Oil sludge or black sludge is a gel-like or semi-solid deposit inside an internal combustion engine, that can create a catastrophic buildup. It is often the result of contaminated engine oil and occurs when moisture and/or high heat is introduced to engine oil.
The Toyota F series engine was a series of OHV inline-6-cylinder engines produced by Toyota between November 1949 and 1992. They are known for their high amount of torque at low engine speeds, massive cast-iron blocks and heads and also their high reliability. The F engine had one of the longest production runs of any Toyota engine.
