This happens because crankcase vapors contain oil, that damages the rubber or plastic, causing hoses and lines to swell and crack. For example, the L-shaped rubber elbows that connect to …

Detonation and Pre-Ignition - MisterFixit

The octane rating of a given grade of gasoline is a measure of its detonation resistance. The higher the octane nuer, the better able the fuel is to resist detonation. Most engines in good condition will run fine on regular grade 87 octane fuel. But engines with high compression ratios (over 9:1), turbochargers, superchargers, or with accumulated carbon deposits in the coustion chaer may

The screw that hits the cam is the cold idle adjustment, and it''s only used when the engine is cold, to keep it running faster

Wire Amperage Capacity Chart - Jasco Automotive Ltd

If your circuit needs 100 amps of current, the battery cable will absorb 24 watts of power because of it’s resistance. Now lets say that your voltage drop is 10%. Now your voltmeter at the other end of your battery cable will read 10.8 volts (12 volts – 10%) and that same 100 amp current draw will cause your battery cable to absorb 120 watts of power! Your cable will definitely get warm to

Hose - Wikipedia

A hose is a flexible hollow tube designed to carry fluids from one loion to another. Hoses are also sometimes called pipes (the word pipe usually refers to a rigid tube, whereas a hose is usually a flexible one), or more generally tubing.The shape of a hose is usually cylindrical (having a circular cross section).. Hose design is based on a coination of appliion and performance.
