i put 10 lbs of boost to mine for like 40k miles and never blew it up…sold it with 110k on it…broke the tranny though…i think that was about the only problem i really had. ---

I’ve put about 100,000 miles on 3 different neons and never really had any trouble with the basic engine aside from the headgaskets. Most of the ones out there now have probably had the headgasket changed since the new leak-free MLS type gaskets came out for them around this time in 1998. ---

They will last you a long time if you take care of them. Only real thing to look out for is running low on oil. Run it low on oil and you will spin a rod bearing with the quickness. Otherwise, swapping to the MLS HG gets rid of an annoying minor oil leak, and swapping out to the PT Cruiser 2.4L lifters will gets rid of the ticking. Once you add some boost it will still run reliably as long as you tune it right and keep it under 10lbs on stock internals.
