Rattling engine 99 windstar
Hi, i have two issues with my engine i need help figuring out.
It rattles pretty loud at startup and then will quiet down almost completely after you give it some throttle, and rattles again when it idles down for a min. Someone told me its probably a firing issue but I tend to think maybe hudraulic lifters/ oil pump problem. please see the attached video.
It sucks air when you give it throttle. you can also hear that from the video link below. I can't locate the vacuum line responsible.
Please help! Thanks scotty!
