Is there any good reason that this cover must be kept on the engine, i remove it when replacing my the oil filter and you have to remove the two small nuts holding the cover down.
I don't see any good reason to have it on let me know if i have missed anything.
No reason to keep it. I threw away mine after I got the 4R and there was a bunch of dirt and leaves trapped under it. Now I can more fully enjoy lovingly gazing at my beautiful, clean 1GR-FE.
