Several years ago I saw a thread here discussing Toyota oil filters vs. the popular Fram filters. I have always used the stock Toyota filter. However, it is a pain to get off and my mechanic keeps "forgetting" to use a Toyota filter. I have a 1984 22r engine. I read in one of these threads that the Toyota filter has a flap inside the filter to control oil flow back into the engine or gunk flow. American vehicles has this flap in the block. Thus the need not to have it in the Fram filter. I have heard that not having this flap allows gunk back into the engine. Can any of you techs out there shed light on this or tell me how to find this thread from way back. Thanks in advance.
