Using this Torque Solution oil pick - up is easy. First, make sure your engine is off and cooled down. Then, carefully install the pick - up in place of your old one following the standard installation procedures for your Subaru EJ engine. When it comes to maintenance, there's not much to do. Just keep an eye on it during regular engine check - ups. If you notice any signs of wear or damage, it's a good idea to have it inspected. Since it has a zinc coating, it's fairly resistant to corrosion, but try to keep it away from extremely harsh environments. Remember, this product comes with a limited lifetime warranty, so if you run into any problems, reach out to the manufacturer. Also, be aware of the Proposition 65 warning about chemical exposures in California.
