Does anyone know if there are any differences in the cps or are they compatable for all year makes?

Are you stating this because of the marks I have on the cps gear?

ok...So before I started taking parts back off to do what I mentioned in the previous post, I decided to first start it up again. Once the engine fully warmed up (~82C) the noise went away...but you can still hear slight whining under load/throttle. On prior occasions I shut down the engine...

I tried to record but the noise was so distorted it was useless. I'll try to get my hands on a dig. video camera and see it the sound quaility is better. As for the bearing, maybe I could hook it up to a power drill and spin it to see if it makes any abnormal noise from the bearings...

I've seen many pictures and all the cps gears have those markings on them. One thing I have noted is that the cps gets very hot quickly so it may be hitting something slightly causing noise and heat. I will lift the valve covers and take a look next chance I get.

Does anyone have a known working spare CPS that would'nt mind sending to me to see if this solves my whining noise. I would pay shipping both ways of course. Or if anyone has one for sale please let me know.

No, the cams were not removed.

No, its definetely the CPS making the noise. I sounds like its coming from the inside by the gear. I set the timing and the noise is still here. The mystery is it was functioning properly...i took it off (sat for 4 months) and reinstalled it and now it makes this whining noise. What...

Okay so there is only ONE o-ring on the CPS. The page in the 92 TSRM is misleading and shows one at the end of the shaft but the link posted above shows a much better diagram. So what about this...if the timing is off a little,would this cause the whining noise or cause any noise at all? Is...

I believe we are experiencing 2 different problems. Mine gets louder when the throttle is open. (only idled, havent driven yet) The car is in perfect running conditon.with 70K...I then tore it down to upgrade the turbo, fuel system, exhaust, electronics..ect. Upon my first start up...

A rebuild is my last option on the list to find the culprit of this noise. Is there an o-ring missing?

Below I have attached a picture of my CPS. I am getting a continuous whining noise that I beleive is coming from the cps. Is there supposed to be an O-ring at the end of the shaft after the gear? If so, could this cause an abnormal noise? Thanks for the input!

Super expensive but nice!

Indeed they do...I got my 92 from an 80 something year old who couldnt drive anymore. He was the original owner with 40,000 miles in mint condition. Great find by the way!

I remember reading a thread about you having problems with them bottoming out and things of that nature? I have megans too and have none of the issues you stated. I beleive yours were defective or something. Tag that link in this thread, I cant seem to find it. As for the leaking, I had...

OP, check this link out...here's my thread on this topoic from last year. Hope this helps. http://www.supramania.com/forums/showthread.php?t=79273

Thanks for the input. I havent seen any 660cc chips but I'd love to get my hands on one.

Anyone?

I am just curious as to whether anyone has tried this and if it even works. Our only upgrade option for the MK3 is the 550cc injectors chip. Would it be possible to run the 680cc chip made for the MK4. If not, I guess it would be safe to say the Mk3 VPC is limited to 500rwhp due to...
