my first problem is every once in a while ill hear a weird noise like metal hitting metal and its coming from the rear end it only happens when im going under 35 mph well at lest thats the only time i hear it i already checked the muffler. and if it helps i have 3.73 gears

second problem is i think my car is burning oil. i changed it about 3 weeks ago with royal purple 10w30 and its already showing that i need to add oil well thats what the dipstick says


thank for all the help

check where the tailpipes go over the axel sometimes that will hit. make sure your exhaust hangers are good.

burning oil thing.. is your check engine light on? you sure you dont have a leak? synthetic oil seems to find leaks alot easier. does your car smoke?

[87gtmustang]

it smokes from the tail pipes it does not all the time but mostly just when it cranks sometimes kind of like the noise coming from the rear end
o and theres grease all over under the hood i gotta take care of that but i dont think its oil

edit
o and no the check oil light comes on but not the engine light

what color is the smoke?

[e3sean]

that could just be moisture build up in the pipes. if its blue tinted smoke thats oil. if its white its just moisture.

greese? you mean burnt oil? where is greese going to come from do you lather your engine in it? j/k borrow a pressure washer and buy alot of engine bright clean the entire engine/engine bay i bet your leaking oil somewhere but you cant see it cause everything is already caked with burnt oil.

You mean like ALL over like on the underneath of the hood itself as well? Do you still have the felt thing under the hood and is it coated in oil as well? If so, it could be your power steering pump or a leak in a steering hose now or in the past. Those leaks tend to throw or squirt power steering fliud around because of the spinning pulley and the fan.

valve seals is a good possibility but hopefully its just the buttload of greese under the hood lol.

the smoke is white and the oil isnt all on the hood theres a very little but not to much and ill clean it either tomorrow or sometime

and if it is the valve stem seals how hard and how much would it be to replace
