How do you stop your Toyota lucida from smoking?

Answer 1

Replace the PCV valve first if it has one. I recommend buying a good quality PCV that is made of metal. I once replaced the pcv on my 86 Toyota pickup with a Toyota pcv that was made of plastic. Two weeks later my truck started smoking severely whenever it was at an idle. It was a defective pcv. I have also purchased defective Fram PCVs. Make sure you are using the correct weight of engine oil unless your engine has a lot of miles or you never change your engine oil. If your engine has high mileage try using thicker oil like 20w-50 castrol in the summer. If you haven't changed your oil in a couple of years then you should change it with the normal grade oil then change it again a couple of weeks later with the normal grade oil. If it still smokes after the second oil change you should change it a third time using thicker oil. The purpose of changing it so many times is to get some of the sludge out of the engine and hopefully keep your oil pump intake from being clogged by hard chunks of sludge. If none of this stuff helps then you need an engine overhaul.
