97 LT1 crankshaft position sensor and wheel?

**JaycenK** · 02-14-2010, 07:44 AM

Hello all I have a 97 camaro that I built a 383 for and noticed that the timing cover on my 97 engine has a crank position sensor. The donor motor that I built was from a 95 and did not have this. My question is this system uses what I guess is a reluctor wheel? that the crankshaft position sensor use for better PCM timing control. Is there any reason I would have a problem with using the old wheel on the new 383 build? I shouldn't have to go get a new one correct? just put it on with the key way for the crank sprocket? The timing set I used is a GM Performance 12370835 for the opti spark II. I will find out soon enough on this, but just figured I would ask to see if anyone knew before I go ahead and do it since I have to change the timing cover over which means pulling the oil pan and getting new gaskets for both pan and cover.

A couple things ... yes, you need the hardware that makes up the CPS. The spacing th gear provides is critical.

What does it do? Checks for misfires only. Just reads and logs data. Unplug it and there are no issues for the motor running, just a CES light on the dash.

For the F-Cars, this was a 96/97 deal only.

I suspect this was R&D for the eventual triggering of the LSx ignition.

yea I noticed that the hub seemed to far back with the other pullies on the front of the motor but I just didn't have evry thing bolted up to verify it yet. I already bought a new hub made for the 96 97 so I guess there is no problem in reusing it?

No problems as long as the reluctor wheel and spacer are in place.

lol

I just put that damn thing back together and I did not have a spacer. What spacer? I hope there isn't one. This will be the 4th set of gaskets if I have to pull it apart again. I pulled the cover and then I saw the ring and I had my puller there and pulled it, walked it over and cleaned it and ... I don't remeber a spacer I looked on the old engine and there is not one still on the crank. Pullies are back on and they look lined up right so could it be there isn't one? Maybe a 96 thing? Hub is nice and tight to the ring wheel?

SumBitch ... I meant "reluctor wheel/spacer"

Damn ... sorry about that ...

LOL good

I was looking around thinking, did I f'up again?

I'm glad cuz those guys at the parts store are out of gaskets, I went through them all. lol Thanks for the help. I hope I am done now so I can get on with the
