[m3f_bimmer95]

please let me know if that solves the problem.....think I have the same problem but for a 95 M. Thinking to do the timing chain too while Im at it just as preventive maintence since everything will be opened up in that area..

[m3f_IIrjII_d3ff03939b]

I'll let you know as soon as I replace it. Just haven't gotten around to it yet.

bimmer95,

you will not have to open anything to replace the primary chain tensioner, it 'simply' screws into the side. If you are going to open that area up than might as well do everything, including the three guide rails, the secondary tensioner, perhaps the upper and lower chain with new sprockets and inspect the thrust spring
