1.6 Miata Cam Angle Sensor O-Ring Replacement + Ignition Timing 

For those who are wondering how to tell which way the prongs on the cam sensor go….they are offset from the center of the sensor, thereby unable to align more than one way. If the sensor won’t go in, pull it out, spin 180 degrees and it should go in. If you can’t see the slits in the end of the cam, you can feel them with your finger and figure out the position roughly to install it.

Dude your lighting set up is too legit dude lol

Oh dude I totally needed this video. Lol perfect timing I just had my Miata timed by ear. But it doesn’t have the ring on my CAS so it’s kinda leaking out the back

i swear ur video quality is better than some 1mil+ youtubers... love ur content... keep it coming

Thanks for the recording ...did mine today, with the cam cover on...(I replaced that gasket when I did the timing belt/waterpump etc.. didn't want to mess with it.. it was not leaking at all. I could not get the CAS our from behind the engine, so I used a plastic interior panel tool and easy broke the decomposing "O" ring off, and put the new one on without bringing the sensor out from behind the engine... a little tricky, put got her done... Those two keys on the CAS are almost the same, and hard to see which cam cut out matches with a mirror... one is about a half a mm wider... Seeing that after a bit the orientation was easier, and got it pretty quick... It looked more apparent on your recording? Incidentally I removed the engine pick bracket, and still couldn't clear firewall and the back of the engine, to get the CAS out?? Got ii replaced ions pipe of the hick-up, and she was leaking. The old ring had a flat spot all the way around from all they years, and broke easily when I pulled on it... Hopefully this is the end of the leaks... as least for now... Differential is weaping a little, maybe I'll tackle that next. Of course I got blood on it... never doing anything without blood...

Thanks guys hopefully it helps me out with my miata I'll hit u up on the update cause I changed my crankshaft position sensor from my other engine

I just got my first car yesterday which is a 1990 1.6 SNC miata it has little to no power in the low revs. And it idles sooooo low. But I can’t wait to get it in the road.

Congrats Hahnpho!

If you want you can get the Viton Quattro CAS O'ring from Miataroadster, it should hold up a lot better than oem and im actually doing this same job on my 1.8.

Thanks for the video !

gotta say great video

If the O ring has gone, would you see the oil leaking on the back of the rocker cover or is it more likely just to be the rocker cover gasket?

What happens if you put the cas 180 degrees/ the other way on line with the crank?

Taking valve cover makes it so you can see it when you align. Don’t need to though usually

Ifnyou wanna make it easier to insert the cas you can take off the valve cover and you can see the prongs from the opposite side
