Hi, i have two issues with my engine i need help figuring out.

  1. 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.

  2. 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!

I'd say get rid of it, cause engine has internal damage. BUT you might try a good engine flush then change the oil, put in a quart of lucas oil additive, and pray that helps. As for the vacuum leaks , replace the booster check valve and pray it's not the booster itself leaking

for the vaccuum leak, i blew smoke through the hose at the red circle and the obly place i saw it come out was under the silver cap at the blue arrow in the picture.

check to see if it's valve or injector noise.sounds like valve noise. and try to find vacuum leaks for sucking noise
