R32 Cas Problem

[vifer]

hi -

Pulled off my CAS to diagnose a no start problem and discovered a half broken splined shaft in it. I tried spinning the CAS shaft by hand but it seems siezed hence why it broke the spline.

I had a look with the torch inside the exhaust cam where the CAS goes and noticed the other side of the broken spline shaft. I tried picking the broken piece with a pick tool but it wont budge.Not sure if it can.

Could someone pls explain if that splined shaft is part of the Camshaft? Cause it doesnt appear part of the CAS. how do i replace it ?

I hate to cough up on a new cam.

cheers

would you be able to post some pictures?

Looking into the exhaust camshaft. You can see the broken bit.

first pic is the birds eye view into the CAS. You can see the broken half moon bit inside.The broken spline shaft piece which came out of the CAS

..The biopsy. A lot of red dust from the seized bottom, bearing after finally turning it using the vise.

Looks like you've broken the spline off the cam. The CAS spline is supposed to be female with a half moon that matches up with the male spline and half moon on the cam

cheers. So that means a new camshaft?

ps: I've posted a Wanted ad in the Forsale section for anyone that has a R32 - RB20DE camshaft and CAS. pm me if anyone can help.

Or if anyone knows where i can pick it up in melbourne.

might be a good oportunity to swap out the motor for something better, if you cant do the labour yourself then you are up for a fair few $$$

I have a pair of standard RB20DET cams, which are a slight upgrade over DE, and a CAS if you need.

I'll be doing the labor myself unfortunately. Otherwise yeah i would consider a swapout.

as long as i dont have to pissfart around with the valve clearances and electronics, timings etc...

Because they both use Hydraulic lifters there is no adjustment for the valve clearances and because the spline/drive on the exhaust cam is the same the CAS are the same.

The DET cams run eight degrees more duration on the inlet and .5mm more lift on the inlet. The exhaust cam specs are the same as the DE.

you will have to pissfart around with camshaft timing and retension the timing belt-you are doing all this with the motor out?

I guess i was trying to say I need a drop in fit. Putting something non stock for the engine gets me concerned a little with having to mess with other stuff.

This is my friends car and she is on a limited budget. Trying to do it as good and inexpensive as possible.

fair enough, i see where you are at, remember when it comes to cars (especially skylines) "good" and "inexpensive" are mutually exclusive terms

I hear ya. I own an Alfa Romeo and an old school Ducati. I know the story line all too well with the exotic.

You don't need the keyway in the cam I ran without for 3 years 400+hp no problem. They just need to be lined up in the right spot again

not sure I understand this. I believe im missing more than the keyway in the cam.
