  • Buick Roadmaster: Sure Methods to Stop Gasket Leaks

    The full-size, four-door Buick Roadmaster entered the automobile scene in 1992 when Buick opted for an early release of the 1992 model year. This followed the Roadmaster Wagon that was launched the previous year. Borrowing the Roadmaster moniker from the 1936 Buick vehicle with a non-limousine wheelbase, the resurrected Roadmaster ran in production until 1996. All of the six later models, however, tend to suffer from an external and internal engine oil and coolant leak that may even mix up to cause engine problems. If you own a Buick Roadmaster, here are ways to address this common problem.

    Replace the intake manifold components

    An engine oil leak, together with a coolant leak, is one of the usual issues consumers must learn to face. If the case is an external leak, it would be easier to spot. However, there are instances when the coolant leak occurs internally, which may allow the coolant to mix with the engine oil. Once this happens, an internal damage will ensue, with the mixture of coolant and engine oil causing damage to the engine bearings.

    The only solution to this problem is to replace all of the necessary components, including the manifold and the gasket. The plastic upper manifold, although not entirely responsible for the leak, tend to get worn out from excessive heat and warpage. The gaskets, which are the main culprit, must also be replaced in order to ensure that no leak will occur again. Both the external and internal leaks should be corrected once the gaskets have been replaced. But do consider to also replace the coolant elbows, the throttle body gasket, the PCV valve, and the injector O-ring seals if necessary.

    Choose the more durable gaskets

    Replacing the gaskets and other worn-out components will stop the leaks, but it always pays to take the fix to the next level. More often than not, the quality and the material of the gaskets will play a major role in ensuring leak-free operation for your Roadmaster\'s extended mileage.

    When choosing the intake manifold gasket replacements, you will be left with either an aluminum-framed gasket or a plastic gasket. Buick owners have reported no significant differences between the two when installed, but there are underlying advantages when you go for the metal-framed gaskets. One of them is its ability to withstand heat and pressure much better than the nylon gaskets, which may require another replacement after 100,000 miles.

    Conduct regular check or maintenance

    Both the engine oil leak and the coolant leak can be prevented, provided that proper care is practiced. This means strictly following a maintenance schedule, as well as regularly changing the oil and coolant. Moreover, gaskets should be included in the list of car components that must be constantly checked. After all, these parts are often made of plastic or rubber, which are prone to wearing out after excessive exposure to heat, among others. Ensuring that the gaskets, along with the manifold, PCV valve, and other components, are in tip-top condition should prevent your Buick Roadmaster from experiencing this common leakage problem.
