I have read as many previous threads as I can and understand that the toyosport knocks once fitted - supposedly due to engine movement worn mounts. I fitted a toyo mainifold and soon as I drove it it knocked when put throttle down. Just fitted upper and lower power flex mounts, I’m sure they work, because even when I start the engine now, I know it is pretty damn tight in there, also got the vibrations etc which I can deal with. Although it STILL knocks ? Any other ideas / experiences on this?
