Hi, I have just purchased some new valve covers from a seller on e-bay called “uforeborn” they have the Lexus embalm on the top and look very nice, good quality around a fiver I think, better than the original Lexus ones at £6 each. Just a bit of advice, don’t use the ones that use a locking grub screw that are suppose to be pinch proof, if kids do try and nick them, they may damage your tyre sensors, and at £150 a go that’s not good, mine have the grub screw but I am not using it, just tighten them gently with a spanner & keep it in the car, also put a little Vaseline on the thread & remove & replace the caps once a month to stop them corroding on, I had this problem and had to use mole grips to get them of, I had every thing crossed that I didn’t damage the sensors, luckily I got away with it.
