Default Clicking noises.

Ok. I have a few concerns about my 2003 Dodge Neon SXT.

When it starts in cold weather it knocks but goes away after about 30 seconds to a minute. As far as I heard this is normal engine knock because the piston rings contract when they're cold but expand to fit when it warms up. Is this explanation and behavior right and charactaristic of most Neons?

Also, There is a stange rapid clicking comming from the engine when it runs. the clicks accur in a steady pace. it sounds like the lifters are clicking but I know I also have a belt problem with squeeling and such, could the sound be from the belt and pullies? or could it be a problem with the lifters? (I put a Qt. of Lucas in it to see if that helped quiet the lifters if it was them and no difference)

The steady clicking you hear are the fuel injectors, nothing you can do to quiet them down. The other engine noise you hear is normal as well, mostly all Neons have a certain amount of valvetrain noise along with the injector click...

That's normal too (mostly when cold)... "piston slap," as you mentioned is relatively normal with our motors... as is some "ticking," or "rattling" from the hydraulic lifters slapping away on a cold start until they get full and warm... these motors seem to make a lot of noise when the weather gets nasty like 0 degrees out. The emissions sensor and solenoid will also make a similar sound sometimes between revs, especially when it's colder out (more fuel = more potential for crankcase gases to build-up). Mine has been making these sounds almost since I bought it new and it still performs like new when it's warmed up, no better or worse.

the constant ticking happens all the time, not only when the engine's cold.

Kinda off topic, but as far as the cold weather goes, here in manhattan, ks we had our first nice 55 degree day since like a month. That just made me think about the sping coming and getting to drive and work on my car again, woot!
