The Speedway 91003041 finned 90 valve cover oil breather is a part used to collect and recirculate crankcase vapors back into the engine oil system. This component can help prevent oil foaming and maintain proper crankcase pressure. Here are some potential pros and cons of purchasing this part:

Pros:

1. Improves engine performance: By recirculating crankcase vapors back into the engine oil system, the finned valve cover oil breather can help maintain proper crankcase pressure and reduce oil foaming, which can lead to better engine performance.

2. Extends engine life: Proper crankcase pressure and reduced oil foaming can also help extend the life of the engine by reducing wear and tear on internal components.

3. Easy to install: The finned valve cover oil breather is typically a straightforward part to install, and can often be done without the need for specialized tools or extensive mechanical knowledge.

Cons:

1. Potential for oil leaks: The finned valve cover oil breather is located near the valve cover, which is an area where oil leaks can occur. Installing this part may not completely eliminate the possibility of oil leaks, and additional steps may be necessary to address any existing leaks.

2. Cost: While the Speedway 91003041 finned valve cover oil breather is priced competitively compared to other aftermarket options, it may still represent an additional cost for vehicle owners who are looking to maintain or repair their engines.

3. May not be necessary for all engines: Depending on the specific make and model of the vehicle, the finned valve cover oil breather may not be a necessary component. Some engines may not produce enough crankcase vapors to warrant the use of this part.

Conclusion:

The Speedway 91003041 finned valve cover oil breather can be a valuable addition to an engine system, particularly for those vehicles that produce significant crankcase vapors. It can help improve engine performance, extend engine life, and be relatively easy to install. However, it is important to consider the potential for oil leaks and the cost of the part, as well as the possibility that it may not be necessary for all engines. Ultimately, the decision to purchase this part should be based on a careful evaluation of the specific needs of the vehicle and the benefits it can provide.

Recommendation:

If you are experiencing issues with crankcase vapors or oil foaming in your engine, or if you simply want to take preventative measures to maintain optimal engine performance, the Speedway 91003041 finned valve cover oil breather could be a worthwhile investment.
