Rb20det CAS making some annoying noise..

[Rb20_POWER]

My CAS seemed to be making a light squeaking noise so I decided to pull it out and saw some gunk inside. Sprayed it out with the compressor and shot some wd40 inside and it fixed the problem for a couple of days. Started squeaking again and i've noticed a light ticking now coming from the CAS..I'm pretty sure it's coming from the CAS, i've listened to everything else with the stethoscope and it sounds pretty loud from the CAS. To get the noise to happen I have to rev the motor to about 2k +-500rpm and it goes away.. Anyone else experience some squeak from the CAS???? Any fixes?

Only true fix is to replace it but you can try to fix it yourself if you have a replacement handy. Because you don't want to mess up your only one with out a good part to put in.

ya i feel it, i was just thinking if it were a bad cas, wouldn't it cause the car just not to start at all?? Is squeaking or ticking a sign that the CAS is about to go?? s***'s really annoying...

i bet you already know the answer to that (not bashing you). weird mechanical noises are a sign of weird mechanical issues. I'd go ahead and source another one and still keep that one as a spare in case you ever need it.

Is your timing cover installed? If it isn't did you use spacers?

If not, time to find a new cas.. odds are that one is already damaged.

Yea usually the biggest culprit is people not using spacers. BTW I have a good working CAS in the classifieds section on here and on zilvia for 125 shipped OBO... Less work sourcing one now!

are the spacers you're talking about the 3 spacers that are on the actual timing cover, within the rubber gasket?? The gasket is toast but the metal spacers are intact..are the metal spacers the only thing needed or do I need to replace the rubber gasket too?? Thanks for the help.

The original question was: Is your timing cover installed?

Without the timing cover, your cas will slide into the engine too far by a couple of millimeters and get damaged. If you are not using your timing cover, you have to use some spacers to keep your cas installed at the proper "engine depth".

We really need something in the FAQ about this phenomenon. So many CAS have died for no good reason!!
