And, it comes to my mind, that Thomas and I promised to give the p/n of that magic Wuerth hydraulic sealant we talked about. Thomas uses it to secure almost any bolt (beside header bolt, head bolt and the like of course).
In Germany it's called Wuerth Hydraulik Dicht (means hydraulic seal) P/N 893 545 050 50g bottle.
As we said, it's magic, seals perfectly up to 200bar, can be used on
oil and secures every bolt, still allowing you to open it again w/o any problems.
This is from our dealer in Germany,
www.Cobra-sued.com. If this doesnt help, send me an email and we'll get you fixed up somehow.
All the best............ Bob
