Howdy Gang, On our '85 Golf diesel- we didn't get a operators manual so1. Where is the switch to make the rear window wiper operate?2. How to remove a plastic cap on the 5th gear lock out- with out breaking it or is it needed to be put back on?3. This motor has 300+kKms on it - I just received the tools and timing belt from eBay and wonder if the T/belt broke would the engine need to be rebuilt -I know that the head and valves would be bent but what about the rods or pistons do they get damaged.4. I installed a real oil pressure gauge and get 75+ PSI while running-Isn't that too much pressure? Don't get me wrong I think it is great but after driving aircooled VWs since early '60s it just seems to be way up there.5. Does anybody here mix filtered used engine oil with the diesel ( it seems like getting free fuel- I've read about WVO but what about used oil?cheershank
