I think I know now where it seats and is adjencent to the vacuum control valve, there is that thick brown vacum hose that goes to the steering mechanism (as you may suspect I am no mechanic but thanks to this forum and the help of you guys I've been able to fix a couple of issues!) This weekend there is good friend of mine that is a mechanic and will probably have the knowledge that I don't have to help me out even though he is not a MB diesel guy -- he also offer to have the engine oil and filter change and the same with the tranny. Can you tell me which oil is the best for my 84 SD 148k and the same for the tranny? what weight? I can buy all this at fastlane. And last but not least would it be difficult to change the gasket where the valve sit, I've have read that it is also good to adjust them...thanks so much guys!!
