Cas/timming Issue

[Ke55pig]

Hey would like some help asap.

When i got my r33 it didnt have a timing cover, so i removed the cas to put the cover on. Then put it back in and now it isnt running so ive put it back in wrong how can i get it back in to atleast get it running so i can then get it with timing light with the right adjustment area cheers.

Did you make sure the CAS mated up the keys on the CAS optical sensor and the one on the end of the exhaust camshaft?

Probably something very basic, are you sure the CAS plug is connected?

In nearly all of the 7,369 threads on this problem, it is mentioned that there should be a half-moon key on the end of the exhaust cam that aligns with a half-moon slot on the CAS. If the key is missing (broken off), then the CAS can align in one of 8 or so positions, but there is only 1 alignment that will allow the engine to start.

Confirm that the key is there first. If it is, then the engine should run - maybe roughly, but it should run.

It is easy to spot the key in the end of the cam:

If it isn't there, you can probably see a rough spot on the base of the recess where the key broke off from. Then you need to visualise how it all looks so you can position the CAS correctly. Alternatively, just keep repositioning the CAS until the engine fires.

with the motor in the car you need a small mirror to see it properly. borrow your gf's make up mirror or something similar
