Using your Torque Solution Heavy Duty Oil Pickup is straightforward. First, make sure your engine is cool. Remove the old oil pickup from your Subaru EJ engine carefully. Then, install the new stainless - steel oil pickup using the provided M6 x 16 and M6 x 10 stainless socket cap bolts. Ensure the FKM rubber O - ring is properly seated for a tight seal. When it comes to maintenance, regularly check the stainless mesh screen for any debris and clean it if needed. Also, keep an eye on the tig - welded joints and the bracing for any signs of wear. Remember, this product comes with a limited lifetime warranty, but if you're in California, be aware of Proposition 65 warnings about chemical exposures.
