Hi all I recently installes a WVO conversion in a 240D I purchased for that purpose. The conversion consistes of a rear mounted 6 gallon marine tank with 1/2 in. copper pipe inside to heat the svo and a copper waterline inside the coolant line to a filter and a 6 port valve ( the kind which is activated by 12 vdc to switch over) here lies the problem. the valve appears to work fine however, when I am running on the veg tank the veg tank slowly starts filling up from the return line..(appears to be diesel) how could this be.. I have double checked the valve connections they are correct... Could it be that this valve is not compatable some how. prior to the rear tank install I tested the wvo concept by hooking up a simple 2 gal tank under the hood to the same 6 port valve with a return line and had no backup... Any one have any suggetions... I do like the idea of having the return to the veg tank, so hopefully that will not have to go.... thanks Joe
The best advice is to skip the WVO conversion and go directly to burning biodiesel. You can phase in the percentage bio-D and this will avoid the problems associated with freeing up all of the gunk in your tank. The benefit of bio-diesel over WVO is that you don't have all of the issues related to coking but you do get the lubricity benefits.

These are coupled with a prototype 463 Cabrio body that replaced the old rusty 460 Cabrio body. Body is unique in that the tailgate opens like a door on a stationwagon rather than like a truck tailgate. The latest addition is the Schmude 5 piece hardtop that gives plenty of flexibility without having to remove the entire hardtop for open air driving.
