Hey I'm new and have looked through the list to find questions on my specific issue but haven't seen one. I have an 89 non turbo that has a knock that sounds like it's in the head. 190k miles. No knock at idle, just when you give it the gas. My question is could it be the lifters or what? I just don't believe it's in the lower half of the engine. Can the lifters be adjusted? I just got this car to play with after selling my 85 Celica GT-S so I am not yet familiar with the MkIII's and would like some advice before taking it apart. Thanks in advance. :1zhelp:
