In addition to the cost of the spark plugs themselves, it is also important to factor in the cost of labor for installation. If you are not comfortable working on your car yourself, you may need to pay a mechanic to install the spark plugs for you. The cost of labor can vary depending on the shop and location, so it is a good idea to get quotes from multiple places before making a decision.
Ethylen-Propylen-Dien-Kautschuk (EPDM)

First, an elastomer, most often nitrile, is vulcanised to a metal ring. This creates a stiffening effect that includes a specialised metal tension spring directly behind the sealing lip, keeping the oil seal firmly in place against the moving part.
Even though it’s better than other materials in terms of toughness and wear time, it is preferably used in dry-running applications. The salient demerit of this material is its cost.

Put a wooden block or a piece of large tube against the seal and gently tap it squarely into the housing until it is fully home. Refit the timing cover, if removed.

It is quite common for a groove to develop at the sealing lip at some point due to long-term use. As a result, the new oil seal no longer fits and seals properly. It is not strictly necessary to replace or repair the entire shaft. Take a closer look at the dimensions first. It may be possible to fit with a slightly narrower or wider oil seal next to the groove. Alternatively, using the Speedi-Sleeve repair kit, repair the running surface under the seal.
