Hi Guys,
Once again I am seeking help with my Car (real jdm silvia 1989 with original CA18DET). I have been searching and trying to track down a squeaking noise that is driving me crazy. First I have checked all the belts and pullies, alternator, AC compressor, power steering etc. What I have come up with is the CAS is the culprit. I have installed about 6 different CAS 3 of them being new ones. After putting in a new or different CAS the noise problem goes away but only to return. I have had professional mechanics check it out with no answers except that they think the engine itself is healthy, my last try just yesterday with a mechanic said it's the CAS. I just happened to have a brand new CAS and it was installed and the noise was gone until today it came back. This guy said that maybe it is because that little tab that is on the exhaust cam to line up with the CAS has broken off sometime in the past and maybe because of that and not having a good lock up with the cam itself causes the CAS to squeak?
My question is has anyone out there with a CA18DET ever have this problem and is installing a new cam the only answer/fix. Can I just replace the exhaust cam alone with let say a stock one or maybe a Tomei hydralic unit that I won't have to adjust my tune and go to the dyno again. Or do I have to replace both. The engine is the original one with only 70k miles.
Any insight or info with this issue would be greatly appreciated.
