Were the cams you are using now from a 420A neon?

No, they're not compatible. You need cams from another 2G N/T Eclipse, Talon or an I4 Avenger with the 420A engine.

Possibly bent valves

The Neon head has the reverse flow of the Eclipse head (basically the intake is on the front side of the engine and the exhaust is on the back side while our Eclipses have the exahsut on the front and the intake in the back). So you are putting the intake cam on the exhaust side of the head and the exhaust cam on the intake side of the head (along with timing differences on the cam gears).

If you were to put the Neon exhaust on the Eclipse exhaust you would have to account for timing changes and cam angle sensor movement.

More importantly right now, you should check for bent valves.

That's a good sign. Put the Eclipse cams back in.

Out of curiousity, why did you try the Neon cams in the first place? Were they aftermarket cams?

this is a common mistake. Well, thinking that the neon and dsm engine are identicle. They are both chrysler and share alot in common; but like mentioned above the head is 180˚ out.

Hopefully there was not too much damage and good luck!
