I just installed an RMS s/c in my car a couple days ago, and immediatly after the install I noticed a substantial amount more noise ( like chattering,or rattling ) coming from under the vanos cover.. It already made a little noise before, I was told not to worry about, so I haven't - but now it's obnoxiously loud when ever under hard loads and low rpm... ( slipping clutch from stop, or into second )
I don't think the whole thing is bad, (I was told I would get a check engine fault if this was the case,and I don't)
My oil level is okay now, but when we first started the car after the install was complete - I did drop about 2 quarts of oil in hte garage, before we realized that we didn't install a washer where we should've, but that was over in about 2 min. when we saw it come out...
So what can I replace to kill this noise ?? Or should I have the whole Vanos unit replaced ??
