So my 89 sc developed a tick yesterday that I am almost certain is a lifter tick because its coming from the passenger side head. Its not an exhaust leak I know that for sure and I took the serpentine belts off to ensure it wasn't an accessory. Its started yesterday to do it randomly then stop. Now its ticking all the time and it follows the rpms so that's why I believe its a lifter. I've hear that like a half quart of transmission fluid mixed with the oilf for like 100 miles will possibly clean it up. Then change the oil and filter back to normal. Has anyone ever done this? And is it worth a shot or will I just scatter my engine haha
