I was thinking that in some situations it could be advantageous to plumb the FPHE in series after the oil cooler on engines that use a coolant/engine oil heat exchanger to cool the oil (ie VW diesels and others)

Once the engine is up to temperature I think you should get higher temperatures here than elsewhere although initial warm up would be slowed as the engine lubricating oil does not warm as quickly as the coolant.

It turns out that I had a bad temperature guage. I picked up a new IR thermometer and found the temp around the thermostat outlet is running 190+ and the heated veg is running 165+.
Thanks,
Scott

Thanks Omar. I now have my own domain.

Thanks, Geno

I'd like to know what you cleaned your intake with.

I let it soak in a Biodiesel bath for a week with occasional stirring. I then used long brushes and a power washer to get the gunk out.

Thanks, Geno

I installed a 30 plate heat exchanger from Omar this weekend. I am extremely pleased! I am not a mechanic, and did not install my Greasecar kit on my 7.3L Power Stroke myself. However, after reading the forums, I figured I could do this pretty easily and I was right. No problems at all.

I used Permatex Hi-Temp thread sealant for the hose barbs on the FPHE. I mounted the FPHE vertically, as the manufacturer's directions stated, under the hood with a large hose clamp threaded through two holes in the body. I ended up installing it in the open area on the driver's side behind the battery. I ran all the hoses and insulated them with foam pipe insulation.

I cranked the engine, it sputtered for about two seconds and then ran normally. No problems with air in the fuel lines. I got it up to operating temp and checked for leaks, and there were none, so I took it out for a ride. Earlier in the day (it was 70 degrees air temp) I had driven it about 40 miles, and the veg oil temperature was 125 degrees. That was the hottest temperature that it reached. After the FPHE install, when the engine reached 180 degrees, I switched to vegetable oil. The initial temp of the veg oil was 94 degrees. Within one minute the veg oil was 124 degrees. Within three miles the veg oil temp was 160 degrees. As I have continued to drive it, I have found that the veg oil temperature reaches within 12-15 degrees of the coolant temperature quickly.

I have a 30 plate, taking heat off the head in parallel with heater core. I put MBenz auxiliary coolant circulating pump on my branch of this junction, stuffing coolant into the FPHE. But on "warm" days, say over 60F, I've found the pump doesn't seem to be needed to speed up FPHE. It reaches target temp just as fast with or without coolant pumping. When the heater core is using its coolant pump, there must be just a trickle flow on my branch when my coolant pump is off, but it seems to be enough. This tells me the FPHE is very efficient. Wow. In my setup, it's also the last device in the line before flows into IP.

Everything is mounted to a bracket I made from a length of 1'x1' square steel. The bracket was notched to bolt to the front core support, an existing hole on the core support was drilled out to accept the 5/16 bolt. The rear is mounted to the unused bracket on the top of the wheel well near the shock mount.

Bolted to the bracket in order from front to back are:
(1) The Heated Fuel Filter
(2) The 2 Solenoid valves (stacked)
(3) The Face Plate Heat Exchanger.

I used a few extra pieces not included in the kit: two 90 degree elbows on the Heated Fuel Filter to help redirect flow downward so the fuel lines would not kink and two 3/8 compression fittings to move WVO from the Heated Fuel Filter to the Face Plate Heat Exchanger using a length of 3/8 steel fuel line bent in a U shape.

Near the top of the photo the two brass HIH "T" fittings are mounted to the firewall. The one near the master cylinder is the return line, and the one near the oil filter canister is the feed line.

Can you expand that first statement. I am going to move my 16 FPHE off the valve cover which is just not practical and rattles too much. I will put it right on top of the exhaust manifold connection to my new water cooled turbo. I could also use the oil cooler lines there though. Any thoughts on this idea? Turbo's get up to 1500F so that water may well be the hottest.

In engines that use engine coolant to cool the lubricating oil (often in a FPHE mounted at the oil filter) the coolant should take on more heat as it cools lubricating oil (once the engine is up to temp). Plumbing a fuel/coolant FPHE in series after the lube oil cooler should get higher temps than plumbing it elswhere.

If you've got a water cooled turbo I expect by plumbing your FPHE in series after the turbo that you will get faster warm up and higher temps than elsewhere - you may however want to confirm this.

Right I will try the turbo and we'll see. The turbo uses the bypass return line to the pump for a feed so it gets the coolest water but coming out that water will undoubtedly be hottest so this should work well. It's the Mitsu TD-04 10 turbo that's replacing mine.
