I believe the original main motor mounts on my '96 Camry four were oil-filled. But aftermarket ones might not be. Any experience, pros&cons, recommendations for replacements?

Happy Motoring, Mark

 

Both oil and solid aftermarket mounts are sold.

Solid lasts longer and may tie the engine more firmly to the chassis but transfer more vibration. As the 4 cylinder tends to vibrate at low speed if vibration is concern recommend the oil filled unit.

Try rockauto.com for both types.
