I cant help with your vacuum problems. My 300TDT suffers from some similar issues such as the 'EC' not working enless I hit the defrost first. What a joy.

The reason I wrote is to ask you about your 85 wagon. Mine has 291kmi and I am nervous about the timing chain although I have been told by several mechanics that the stretch is fine and I dont need to change it. Have you changed your timing chain? What are you thoughts?

Thanks,
Alec.
