Using the DRAG CARTEL Lower Timing Chain Guide is straightforward. First, remove the oil pan. Then, you can easily bolt the guide in place using the included premium mounting hardware. When performing a cam swap, this guide will keep the timing chain in place, so you don't have to worry about it slipping off the crank pulley chain gear. As for maintenance, regularly check the guide for any signs of wear and tear. If you notice any damage, replace it right away. Also, make sure to keep the chain clean and lubricated for optimal performance. Remember, this guide fits both K20 and K24 engines, so it's a great addition to your engine setup.
