WVO/radiator idea

I'll be the first to admit that I've been lurking in some threads concerning WVO and I haven't run as much as a quart of crisco through my diesel. With winter fast approaching, and the short commute I have, I'll probably do biodiesel if I do anything. Anyway, following my elegant breaking of my radiator neck, and replacing my radiator with a new aftermarket one, I got to thinking about the radiator construction. Here's my idea.....it looks pretty easy to take an old radiator and some parts from another and have a nice heat exchanger right in the top of the tank. I know it's been done using the lower tank with trans cooler when the car has a manual, but I'm thinking of cars like mine, an SD with an automatic that needs the trans cooler for the trans of course. With a little bit of modification to mounting of the shroud, overflow tube, oil cooler and vibration isolator that holds the radiator top, maybe this would be useful to someone. I took 3 tank ends off in less than 1/2 hour and I think that with some RTV and a little patience you would have a nice setup. BTW, I closed the hood with this in place and snaked my arm up so I could pass my hand across the top of the larger tank - it's OK, and will fit. Yeah, I know it's a bit warped, but if there is anywhere where warped is appreciated...............

Are you talking about replacing the top of your radiator with a bottom section, basically having two bottoms? One for trans cooling and one for WVO heating?

Only problem I can see is that the period when you really need to heat the WVO is when the engine is cold, therefore no coolant flowing through the radiator yet. That's why most WVO kits and homebrew designs use electric heaters, or they tap into coolant flow from the engine block.

you're right about that. That's why the last 2 pictures are really just meant to feature the nice little heat exchanger that's inside the bottom of the radiator. Rather than making a heat exchanger (which is at least some work, I've designed and/or made several), perhaps these would work well..The outside could be wrapped in electrical heat tape and insulated. Or exhaust gases could be ducted through the ID of the heatv exchanger and be controlled with a heat riser type mechanism. This might be a great use for the EGR system. Think about it, an EGR valve is provided variable vacuum to allow exhaust gases to pass through and heat up the WVO tube. Once desired temperature is reached, the EGR could be modulated to maintain desired temperature.
