Another significant advantage of fiberglass storage tanks is their durability. Unlike metal tanks, which can corrode or rust over time, fiberglass tanks are highly resistant to corrosion and chemical attack Unlike metal tanks, which can corrode or rust over time, fiberglass tanks are highly resistant to corrosion and chemical attack
- In conclusion, the humble 7mm spark plug wire may go unnoticed by most drivers, but its influence over an engine's efficiency and longevity cannot be overstated. As we continue to push the boundaries of automotive technology, it's comforting to know that some fundamental components like this wire remain constant in their importance and reliability, quietly ensuring that our vehicles fire on all cylinders.

If these specific tools aren’t available, it’s entirely possible to correctly seat an oil seal in its housing using a hammer. Ideally, this hammer will be plastic or rubber due to it’s more forgiving nature. Using this and a strike plate that covers the entire seal will lend you accuracy while driving it in. The downside to this method is the inability to drive the seal any further than the strike plate will allow.
Oil seals increasingly had to meet higher requirements, which is why PTFE was developed in 1980. This variant can better withstand higher engine speeds, higher oil temperatures, longer oil intervals and modern lubricants. In addition, the oil seal contains a wider contact surface, which ensures less wear.

There are different types of spark plugs available on the market, each designed for specific engine types and operating conditions. The most common types are copper, platinum, and iridium spark plugs. Copper spark plugs are the most affordable and provide good performance for everyday driving. Platinum spark plugs offer better longevity and performance, while iridium spark plugs are the most durable and provide the best spark performance.

Insert a tyre lever or large screwdriver into the starter aperture so that it jams in the teeth of the ring gear on the flywheel .
Regular inspection and replacement of oil seals are also important for preventing leaks and maintaining the efficiency of high-pressure systems. Over time, the seals can wear out or become damaged, leading to oil leaks and potential system failures. By monitoring the condition of the seals and replacing them as needed, operators can prevent costly downtime and repairs.

Oil seals, also known as shaft seals, are radial lip type seals which are primarily used for retaining lubricants in equipment having rotating, reciprocating or oscillating shafts. The rotating shaft application is most common.
