hello,
I got a mid 80's VW LT28 about a month ago. The last owner told me it ran fine with oil, even 100% although he advised 30% diesel. So I trusted him, running with 70% WVO, even though it only had a one tank system. Now the fuel pump leaks significantly after I only run about 200 kilometres.
There's been some cold days, about 10Celsius or 50 fahrenheit.
Today I disconnected the main tank and run straight from diesel just to check. It leaked more than before. In about 3 minutes (wish I had a watch) 1 litre went through although most of it must have gone back through the return to the main tank. But the pond underneath seemed bigger.
Any guesses what may be the cause and how to fix it? It seems I will have to take the pump for an expensive repair.
I have heard oil may damage the gaskets, or cold oil being more dense creates a lot of pressure inside the pump, also possibilities of glycerin buit up. Any other ideas or what seems more plausible? What can I do about this now?
