My 93 altima runs good but there is a rattle under the valve cover . it has around 180,000 miles ,is there anything that can be adjusted or whats next ?the cars only problem is the struts sounds loose... thanks for any help sherman

rattle under v/cover i'd think timing chain & or guide is loose/worn.best to pull cover, you can see enough from there.good luck

My 93 has the same rattle and same mileage...interested to hear what you find out...

could be a piston seal or something like that. what kind of noise it it? if its a metallic sound it could be a rod or somethin like that but i would get it checked out
