Take out your injectors and pour marvel mystery oil down each one. Let sit for a few days, then slowly manually through the front crank case pulley start working engine back an forth. Use a pipe over the breaker bar for leverage. Make sure Marvel comes to top of injectors. Undo your compression release and once engine starts to break free, remove all oil by spinning the engine manually. If you use the starter motor there is a chance you’ll bend a rod. If you free it up change oil, run engine and after it runs and gets hot, shut down and replace oil with a good synthetic. Good luck, Jack
