Hello,

Recently I changed my head gasket on my motor and my friend decided to help me do so. He took off my CAS for god knows what reason and we discovered the halfmoon from the exhaust camshaft inside the CAS it had been broken off from the camshaft you can also see where the halfmoon used to be before it snapped. The cas still works fine we spun it around while turning the car on and the injectors are ticking, however when we try putting the CAS back on the car will not start.

Could someone tell me what I need to do to get it working again?

Do I keep trying to align the CAS and hope for it to work or do I need to buy another camshaft?

Thanks

As Cal said, it's not too difficult.

You can see up the end of the camshaft with a torch, so rotate the crank until the remains of the half moon are in a convenient spot, horizontal, vertical, whatever.

Then turn the CAS drive to match and offer it up.

With luck it will go straight in, but just leave the 3-setscrews out, connect her up and start the engine.

Timing light will tell you if the CAS is central (approx) in the slots and if she's not, you know how much it has to move and in which direction.

But can you tell if the broken half moon is an old break or recent?

You don't want that bit of metal down inside the cam belt cover.

    • I’m not sure what happened I told them about sonic tunes free OTS tune and the next the I know .. I was booted..   To funny 
    • Yea - I mean I've seen my fuel pump which is decades old and uh, while I'm not saying this with real knowledge... but I sure get the ick at using anything in the fuel system that produced the state of that pump. Many years ago I went through multiple pumps (and strainers) before I dropped the tank to clean it out with extreme violence. I'm talking the car would do maybe 50km before coming to a halt, which resulted in me cleaning out the filter with some brake cleaner and going on my way. None of my stuff ever looked like what came out of your fuel tank. I don't think I'd be happy with it unless every single component was replaced (or at least checked/cleaned/confirmed to be clean here).
    • I'm not going to recommend an EBC pad. I don't like them. Just about anything else would suit me better. I've been using Intima pads for a while now.
    • Agreed, and in particular the earth strap that should go from the subframe to the chassis but it often broken or left off. There is a section in the R32 workshop manual you can follow for troubleshooting if you don't see anything suspicious, and depending where you are (there is no location on your user profile) you should be able to get your hands on a second hand replacement unit still if needed
    • Yeah they mention as a R34 for 2.5 Turbo...but then again thos "small" were also for R34 by that different site. But i look into it and that 310mm EBC is for R34 GTT. And by those you linked the specs are the same 🙂    EDIT: I found these on one site here: DBA 4000 series T3 DBA42304S They are 310mm...and it says are for R34GTT...are there good? EDIT2: ok they have pads too.  What "color" should i get for street use? I dont want/need some noisy ones...(and if they are not that dusty that is good too)
