I am nearing completion on my landcruiser (80 series 1HD-T) conversion.
I am wondering if it is better to put the flatplate heat exchanger (FPHE) either just before the injection pump, or before the changeover solenoid (in this case the relocated one from between the 2 tanks) I have another heat exchanger to put before the filters.
If I put it before the IP, the oil will be very hot before the engine, the solenoid will have cool(ish) oil going through it, the IP will have been pre-heated on diesel.
The question I have is though, will the heat exchanger flush out well when I shut down, or will it still have lots of veg oil in it in its cavities? I am having flashbacks to my gemini which shared a fuel filter for both diesel and veg, and it would not flush between changes, which made starting near impossible.
If I put the FPHE before the changeover solenoid, the engine will run on either cool diesel ot heated veg oil. When I start however there will be a time when cold oil is going into the IP (which was sitting in the hose), folowed by very hot oil (that was sitting in the FPHE) and hot oil will be going through the solenoid. Will this be a problem?
Your thoughts please?
