Ok guys i need some help i cracked the block in my 99 in the typical place by the freeze plug, is leaking water/anti-freeze. I am rebuilding an 02 block to put in it but i am useing my 99 head... is there going to be any problems, what do i have to swap out, is it possible????

---AutoMerged DoublePost---

oh and i have been told something about the crank shafts needing to be swaped but i have also been told that it was bull ****... oh and i also have the 02 head and 02 computer system if u guys can think of something better to do with all of this. And i already have tryed liquid glass, bars stop leak, high temp cold weld, and jb weld on it nothing works the crack was to big, so i have already pulled the block

 

Who told you that youd have a swap crankshafts???? Im sure the head will fit like a glove.

Should be a pretty simple swap. Although I am not aware of the electronic differences. You "might" need the wiring harness from the 02 if you can get your hands on it. Im sure some else will know for sure.

One difference Im thinking of is that the 99 has a crank position sensor and the 02 has a cam position sensor but I think overcoming that is an easy fix.

Is the 02 block a HO or a SO?

 

humm im not sure about it beeing an ho or an so but ill find that out tommorrow and let you know... it came out of my uncles 02 so im sure i can find out but thats a load off my chest about the crank shafts THANK YOU

 

The wiring harnesses have some minor differences, mostly better-shielded connections and sensor leads. You may need to fool around with the connection for the MAP, depending on whether you have the '02 original, or the "new & improved" version.

 

see about the Map sensor i have a boost fooler pluged into it but now that the block is out I should be able to get all this electronic stuff figured out..... this kinda crap makes me wish i would kept my 1st gen...

 

Does the 02 crank have the tone ring on it, since it does not use the crank sensor? If not you will have to swap the cranks.

 

its an HO came out of a 3500 6spd.




ALTHOUGH I FOUN THIS INFORMATION... WHAT WHAT DO I NEED TO DO NOW?

Engine RPM and timing are derived from the Crankshaft Position Sensor (CKP) on 1998-2000 models. A 35 tooth tone ring with a gap where the 36th tooth should be is bolted to the crankshaft. A hall effect sensor registers each tooth as it passes and sends the signal to the ECM. The tooth gap corresponds to 60 degrees BTDC of cylinder #1.
A Camshaft Position Sensor (CMP) senses a hole in the back of the camshaft drive gear to check for TDC of cylinder #1. This signal is used for diagnostic purposes and is not used to control the fuel system.
The crankshaft position sensor was deleted for 2001 and 2002 models; engine speed, crankshaft position, and injection timing information will be derived from the camshaft position sensor signal. Notches are cut into the rear face of the camshaft gear. A hall effect sensor registers each notch as it passes, and sends the signal to the ECM. A missing notch corresponds to TDC of cylinder #1.

 

If it was me, I would check to see it if the 02 crank has a tone ring first. If it does just use the short block and use all the electronics and head off your 99.

 

ok ...sry but how excatly can i tell if it has a tone ring?? and THANKS ALOT for the help

 

Hold on I'll go get a picture
