Jhon, The Honest Mechanic
Jhon is a working mechanic who has spent his career under the hood of American trucks and SUVs. He wrote these books to share, in plain language, what he checks before anyone buys an engine.
For years I kept this information in a shop notebook, telling one customer at a time which engines to run from. I finally wrote it all down because I watched a man in his sixties get talked into a truck with a documented lifter problem, twice, by two different salesmen. He didn't have a mechanic in the family to warn him. Most men don't. This isn't a glossy best-of ranking built to sell magazine ads. It's the list I'd hand my own father before he signed anything. I condensed my service bay notes into engine codes and model years so you can check your own truck, or the one you're about to buy, in minutes instead of guessing. You've earned the right to know before you sign, not after.
