why do I hear a rattle or vibration from the engine area when cranked cold?

Yea i bet something is loose, but a quad 4 has a few things i may be able to help with.

Quad 4 four cylinder. I think it could be bad motor mounts since it quiets down after engine gets warmed up good. Does anyone agree?

Two things i suggest, listen under hood as soon as engine is started cold, timing chains make noise when cold due to worn componets. Also check cat converter for defective catalyst, may not rattle when warmed up. Motor mounts could be worn as well. But i am just guessing on all of this.

Hi zip i have a problem i will post the question think about it and see what you think 02 Civic sedan 1.7.

Hope the response helped , I replied before I saw this response>........never mind!
