I have a 97 Ranger, 4.0L, auto, 4wd with 64,000 miles. I have heard that the 4.0 has problems with lubrication in the head and that valve guides go at 150,000 or so. Is this true and if it is my next question is if it would be smart to use a synthetic oil. I know you should use conventional oils on older engines so it doesn't "slip" past all the worn parts so is it too late on my engine? Any help is great
