00 Head on a 03

bennettmotorsports · Post by **bennettmotorsports** » Thu Apr 28, 2011 6:42 pm

Will a head from a 2000 fit a 2003 Neon? I am looking at a 03, I don't have many details yet but they say the head is bad. I actually just changed the head on my 00. I have the head at the machine shop getting shaved. I am putting new valves, valve stem seals , spark plug tube seals and such in this head. If it will fit it seems like a match made in heaven...lol

It will fit just fine. However I think there is a very very slim chance that the 2000 head would have a working EGR port on it. If the port is already blocked off, great. If not, you'll need to block it off. None of the 2gn gen cars (with the exception of a very very few early '00's) used an EGR system.

Yeah the 00 head head had an EGR block off plate. I had to use that on the head I put on the 00 when I swapped it. The head on my 00 now is a 96 head. I have all the fixin's and figured I could end up with an almost brand new 00 head that could go on this 03 if I get it. I figured they were the same or close to it.

Correct.... The 2000 model year cylinder head will have an EGR port, but it has a 'block-off' plate, installed at the factory.
Some 2001's may have this block-off plate as well.

As long as the block-off plate is installed (of course), the cylinder head will bolt up and work just fine.

just a note of caution, in 2002 Chrysler changed how the cam shaft sensor picked up the signal from the cam sprocket, you may have to swap your sprocket to have the correct signal for the PCM.

The sprocket ?? Or do you mean the magnet on the cam ??

the sprocket has nothing to do with it...

the 03-05 cam magnet is different from the others...you'll need to swap cam magnets for the car to run right...

I think I am just going to rebuild the one that is in it. It only has 2 bent valves. So I will buy the seals and stuff to totally rebuild that head. Maybe $100 total for it to get done. I can get it shaved if needed for $35.

Check for signs of contact in one of the other cylinders. The R/T head I bought had two intakes that were obviously bent. But two of the exhaust valves were also bent. One had .003" run out and the other had .005". It will be enough to lead to a burned valve/seat. I had all the exhaust valves re surfaced, and the two that were "dinged" also were re surfaced with no problem. The face is just a little wider on one side, but it is barely noticeable, and "within spec". They have given me no troubles.

Swapping the cam magnet isn't a big deal, if you want to put the '00 head on, then rebuild the '03. You could swap the whole cam if you like.

I know they were in the #3 cylinder. So I am going to put 4 new valves (2 - intake and 2 - exhaust) And I am going to check the other ones. I would do all 16 valves but at about $11 each its not really cost effective. I am planning on getting this one put back together and probably will sell this one. If I was keeping it for a while then I would put more into it.

It will be either the intake or exhaust, not all of them in one cylinder. The intake most likely, as they are a bigger target.

I was referring to an 02 Intrepid that was in our shop with a 2.7, the sprocket was different in 02 when Chrysler went to the NGC controllers the engine we used was for an 01 and down, did not know that 2.0's had a cam magnet, sorry if this caused any confusion.

The 2.0's (Neon's) went to NGC in '03, and only changed the cam magnet as far as the cylinder head assy. The sprockets/all else are the same.

Edit: It's all good. This is why we are here: To learn something new.

Or get into pissing contests.
