THE VALVE R RATTLING PRETTY BAD IT HAS 5000 MILE ON IT IT HAD 2200 ON IT WHEN I GOT IT DONT KNOW IF THE PERSON BEFORE HAD THEM DONE .DO THEY HAV TO THE ADJUSTED WHEN ITS NEW?

Thats pretty hard to do since each persons stride is different. If you know your stride length then you can just multiply the length of your stride by the number of strides. S x N.

ther are some serius issue--car is 22yrs--try changn fluid-dont flush--also ajust throttle valve cable at intake--chec out linkage at the sticshift--cud be torque converter too--------hav a trans apecialist test drive it--if not comfortable with verdict getta 2nd-------u can buy jaspar trannys with 100thou mile warranty on um

the term ugly or pretty is the perception of some one who has not had the opportunity of really getting to know you. Remember that if your looks are upsetting to others then they cannot see in your heart how pretty you are and a pretty person may not have a heart which really makes then less than ugly. Be happy in the knowledge that the person that upset you is not all that good looking as their heart is ugly and their mouth is bad.

It depends but they are usually about one mile, or half a mile and the horses circle it twice.

the warranty is specific to the paper.. If the text dont state a window.. There is none.. The would argue it was supposed to be brought in before 5000 miles..

no it isnt a stupid question.. A lot of people ask that type of info :)

I have a 2002 maxima with 75k mile and heard a rattling which died down after it warmed up.

It was a bad timing chain pulley. Don't wait too long before fixing that!

If the rattling changes with the revs of the engine, it might be that the valve compensators are either worn or not getting enough lubrication. 20V engines have quite small oil passages travelling to the head. They tend to clog up with gunk if the oil change is not frequent enough.

change fuel filter; add a can of SEAFOAM to Premium gas. add SEAFOAM every 3-5000 miles. ethanol gas problem. check the plugs, may need to be changed out also.

Sorry I couldn't help.
One other thought... I have run into brand new batteries that were bad. It drove me crazy until I discovered it was just bad batteries. Some batteries were good and some bad in the same package!

Happy New Year to you too!

I assume you mean low idle speed 500 rpm. Genarally a tapping noise comes from the valve train, and a knocking noise comes from the crankshaft connecting rods. The way that a mechanic will narrow it down is to use a mechanics stethoscope. You can get one pretty cheaply at an auto parts store. Put the metal end of the scope on a part of the engine and listen for noise. On the other hand, if your car is idling at 5000 rpm, it would also be making ALOT of noise.
