To tilt the engine forward, you need to adjust *both* the passenger side and driver's side motor mounts simultaneously. Here's how to approach it:
1. Identify the Adjustments: Make sure you understand how *both* your motor mounts are designed to adjust. Some have eccentric bolts (oval-shaped bolts that allow for tilting) while others, like yours, have a sliding mechanism with a set screw. The driver's side mount *must* also have some means of adjustment.
2. Loosen Both Mounts: Before making any adjustments, significantly loosen the mounting bolts on *both* the passenger side and driver's side engine mounts. Don't remove them completely, just loosen them enough to allow for movement.
3. Coordinate Adjustments: Now, carefully and simultaneously adjust both mounts. If you loosen the passenger side set screw and slide the mount to tilt the engine forward, you *must* also adjust the driver's side mount to compensate. This might involve loosening an eccentric bolt or another sliding mechanism. The goal is to maintain roughly equal pressure on both mounts and achieve the desired tilt. Small adjustments are key here.
4. Check for Interference: As you adjust, regularly check for interference with other components like the steering rack, exhaust system, or bodywork. Engine tilt is usually limited.
5. Tighten Securely: Once you've achieved the desired tilt, carefully tighten the mounting bolts on both mounts. Make sure they're torqued to the manufacturer's specifications. Torque specs can usually be found in your vehicle's repair manual.
Important Considerations:
* Repair Manual: Consult your vehicle's repair manual. It will show you exactly how your engine mounts are adjusted and provide torque specifications.
* Jack Stands and Safety: Support the engine with jack stands to prevent it from falling. This is crucial for safety.
* Professional Help: If you're uncomfortable working on your vehicle's engine mounts, it's best to take it to a qualified mechanic. Incorrect adjustment can lead to serious damage.
* Why Tilt? If you're tilting the engine for a specific repair or modification, make sure you understand why it's necessary and what the correct amount of tilt should be.
If after loosening both mounts and attempting coordinated adjustments, you still can't tilt the engine, there might be a problem with the mounts themselves (worn or damaged) or something else is preventing movement. In this case, professional help is strongly recommended.
