This was done by a local tuner on my car. It aI'm no car expert, but I don't really think this pink sealant is necessary if the gasket is installed correctly. I don't mind the ugliness of this; I'm worried about is if it will pose an issue later down the road. I would have supplied the shop new gaskets if I knew this would be an issue, but they never said anything.
Also, it does not really instill confidence that they did a good job either on the rest of the installation.
This is a picture of another person's setup. As you can see... no pink adhesive.
