today i started my 2003 neon, and it is -10 degrees f. here, when i first started it the engine made all sorts of wierd noises, now it hasa ticking / knocking noise coming from it, it does it till the engine warms up, any thoughts?

 

Neons dont like cold weather mine sure doesnt. Mine does the same in very cold weather.

 

What weight oil are you running?

 

Piston slap, as soon as it get's really cold most Neons do it. Don't be too concerned as long as it goes away within a minute or so.

 

ok i was just wandering, im running 10w-30 full synthetic

 

the really weierd noise goes away in under min, but the ticking/ knocking noise goes away after 5- 10 min of running, i let it warm up for about 20 min before i drive it

 

My car absolutely HATES cold starts. It makes about 4 different noises when it's started below like 10 degrees.

 

Go with a 5W20. It'll be better for the cold weather.

 

yah it is hard to keep changing the oil based on the weather where i live, one day its 65 degrees and the next morning its -10, then the next day its 55 degrees, it crazy weather, with all my other cars i usually run 10w-30 year round, plus my car is stored inside a heated garage

 

5W20 is fine year 'round.
