Question about 2000 Toyota Corolla
I posted a problem a while ago and was not very specific about the problem. I have a toyota tazz, the SA version of a Conquest. When driving at high speeds and high revs(not over revving) the bolts used to lock the adjuster stud on the engine valves tends to get loose by themselves. is there a way to fix this, as I do not want to blow the engine by bending or breaking the engine valves. (I do know what damage they can do when landing on the pistons!)
To my knowledge, it should not loosen up by itself. If it does, then it is possible that they are worn out and must be replaced. Alternately, on some engines I have worked with, there is a locking nut that is used to tighten in place the adjuster stud or in some cases a double nut, that is one nut to lock in place and another to lock the first. On high revving bike engines, I also use locktite (superglue). Of course the pieces must be initially clean of oil otherwise the glue will not adhere.
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.
Good luck and kind regards.
Thank you for using FixYa.
