HELP

Quick story since i dont feel like typing in detail, i will later if need be....

My car was making a ticking noise (not the normal neon ticking. it is much much louder), mechanic said it was th crankshaft bearings...got those replaced got the car back drove it for a day ticking came back (keep in mind the loud ticking) took it back to him and it looks like im going to need to replace the engin...Before you all say to swap it, thats not an option at the moment. Getting the car back on the road to communte to school and work without trying to borrow a car from a family member is the goal here

Anyways my pap called around to some junk yards for me and found a few engines...one place wants $750

and then he found a 02 with lower miles than mine for $400...but what everyone is telling him is that the 03 engines were a one year deal

personally i did not know that and we all know th procedure of getting it reflashed and all that bs...

Now my question is:

does the 03 engine really differ from the 00-02 and 04-05? Obviously it must be a pcm difference if what these places are saying is true...

really need help on this guys, i miss driving my baby

I'm almost positive the sensors and what not are different for the ngc shit.

But I don't think there is a difference from 03 to 04-05.

2003-2005 blocks use a different crank position sensor than 1995-2002 blocks. So you’ll need a 2003+ block.

I’m guessing your mechanic didn’t put in crankshaft bearings. Instead he put in rod bearings. If this did not cure the tick than you most likely have a bad wrist pin or damaged piston or cylinder bore. A “good” mechanic would have checked this while putting in the new rod bearings.

maybe thats what it was rod bearings...its been in and out of there so many times its getting rediculous

so then what would need to be done to run the 02 block?

Plus an oil pressure check would have been a good idea. If the pump, or relief valve is bad, new bearings won't do much good.

The early 2gn engines are generally more expensive used than NGC engines. Almost makes me want to convert, if I needed an engine. Of course there is MS....

Not possible without some really ghetto engineering or some incredible engineering. Neither of which you know enough about to make work. Just keep hunting for a block.

Way too much. You would need to use MS, and/or swap the entire harness/PCM. The NGC crank sensor is a far better design than the 95-02 set up. The NGC blocks are also stronger.

Since you don't have a lot of time to work with, just get a complete '03 - '05 engine and swap it out.

If you did have time, you could either boost it, which is always a down the road possibility, or get some '02 - older pistons installed for a little better compression. 9.3 upped to 9.8:1. If this is all you did, you would see a small amount of power, and prolly better fuel mileage. But IDK how many miles you would need to drive, to pay for the extra work needed. I don't see the NGC PCM throwing a fit, because it has no way to tell the C.R. has changed. They haven't implemented sensors for that yet.

Good call demons. If I found a good body NGC neon with a busted timing belt, I would toss in 12.5:1 internals, run ethanol, and DD the crap out of it, getting 35+ mpg with a stock cam. But in an 87 octane world, 1st gen DOHC internals would yield 10.2 or so, which would be plenty safe, especially how detailed knock based timing retard is in the NGC. 93 would be better and more fuel efficient at that point, but may not be enough to offset the cost.

hmmm...you guys got me thinking now

i do wanna boost, but i need to get my car running soon

but i still have no idea what that ticking noise is? im just really fed up with this car haha

It would suck if you went through all that trouble for an exhaust mani leak.

yeah it would....wouldnt surpirse me though haha

found a 03 engine today, called around all the JY today, it has 57k miles which is only less than 1k less than mine has now...they want $475

probably going to get it since its fairly cheap and i need this thing running ASAP

You only got 58k on the motor? Dam...
