Shortly after installimg an m5430 intake cam my 2.8 tu it developed a terrible marble like noise on trailing throttle from about 1800 rom down to 1200. Quite loud. Vanos I thought so we installed the well known vanos kit. No change. So then a brand new vanos unit because the noise was coming from that area. No change. Then a new oem side timing chain tensioner. No change. Then a month ago a new top timimg chain tensioner. No change.
Then a week ago the side timimg chain tensioner from an s54.
Silence. No noise. If I had known to try this first could have saved a lot of money.
