Ah that's a relief Mottati, thank you. As no-one else reported any increase in noise with the new cam chain tensioner I thought I was being a little paranoid.
It is quite noticeable but not overly worrying.
I'm hoping as some miles go on it it'll quieten down.
I tried one on my and it whined badly, so I went back to the original set up - silence! I seem to be on my own here but I don't see this as any upgrade, if the chain whines it's probably too tight and a potential problem.
Not alone here gents. I think we've discussed this in another thread a while back, but my car was the same. Rebuilt motor with all new timing components and S50 tensioner and I thought the chain whine was "excessive" so I bought all new S38 tensioner parts and fitted that to test... lo and behold: silence.
The conclusion we collectively came to in that other thread is that the S50 is a good upgrade but maybe not completely suitable for a brand new motor. Once things slacken off and wear out a bit I will re-fit the S50 and see how it goes.
