  • My dealership sold me torx head bolts for my '83 528e when I did a valve job at 217K. They are one time usage stretch bolts that are not normally tightened with a torque wrench but tightened to a torque angle. I have a page out of a tech bulletin but it does not show the number. Interestingly, with these bolts, you do not have to re-torque after a heat cycle. Tighten once - forget.

The part number was 11-12-1-726-478, list price $31.32 in 1993.

  • I bought my '83 528e in 1986 with 37K miles on it. I took it in for service at about 42K and they came up with a list of stuff they felt like it needed including a new head gasket (it was misting according to them) - no pressure, just a recommendation. I never did any of the stuff they indicated at the time. Oh, sure, I did it eventually. The head gasket I did at 217K as noted above. I think the valve job at that time was premature however. I mis-diagnosed a problem!



ps. I have since developed an excellent relationship with parts and service guys at the dealership - so much so that they refer people to me for CCA info or if someone is looking to sell their car privately etc. They have also called me to see where they could get parts for 2002's (which I helped them find).
