That color grows on you. At first I was 50%-50%, but now I am thinking I would not have it any other way on the car.

Ah, greazzer, you told me about that massive heat exchanger when we spoke. wow!!! How many "plates" is that one? Biggest I ever used was in my old 300CD, a 30-plate (or so it was claimed). I was going to stick with my little 20-plate for the '87 300TD (sadly, using over-the-counter Bosch injectors, now, and running well but I had preferred to use yours. so sad!!) good luck with this awesome project.

MISSED 1985 300CD Blue/Palomino 250k lovely but had to part with it; now wife has Jetta TDI, you know how it goes

What is an HE please?

I believe it is Heat Exchanger.

Yes, my bad. HE = Heat Exchanger. Burning WVO, IMO, requires pre-heating the grease. This permits at least one full quart to be elevated to 175F-ish at any given time. There is some lost heat from the coolant. That sized HE can handle up to 300K BTUs, so it is "over-sized" for the job since a gallon of #2 or WVO does not even have 200K BTUs in it, but this was the only size to meet my performance objectives.

Aha! That's why it looks a bit odd for a battery. I suppose you have detailed this in a section I have forgotten or skimmed over. The battery in the trunk then?

Those RED leather seat covers look impressive; however, it seems to be the wrong shade of red for my car. Did you have that matched to your existing interior or are you doing a color swap?

What is your performance objective? Surely not consuming fuel at the rate of a tug boat. 60 plate HE is way overkill, a 20 plate or even 16 will do. Locating it at the battery tray is the worst possible spot in the engine compartment, by the time the WVO makes it diagonally across to the IP, it will have cooled off a little. The HE should be as close to the IP as possible. The battery should be as close to the starter motor as possible- the trunk is furthest from the starter motor, not to mention the voltage drop with a long + 12V wire run and danger of shorts/ fire. Sorry, makes no sense to me.

Interior: Brand new LEATHER. Major interior color change. Mercedes red, actually pebble grain, leather.

Battery is under the seat. Actually, two PC950s from Odyssey (sort of like the antigravity battery), so CCA is 1900 / batteries run in paraelle. Running a battery cable less than 10' is nothing ... that is why BMW as well as Mercedes do it. I am guessing their engineers got it right to some degree ... Plus, I used to have my battery in the trunk for over a year and NEVER an issue. That was one Group 49 battery with 17+' of cable, so not sure what "problems" that would cause.

As for the HE placement, WVO does not lose heat that way. Not really a subjective position, but just the chemistry and physics of grease. So, as for "heat loss", I would agree there is an academic amount, of perhaps a 10th or 20th of a degree traveling 35" or so, but I am not sure how 1/10th or 1/20th of a drop in 1 F is measurable except thru mathamatical calculations but I highly doubt felt by the engine itself. As for volume, unless you have a closed loop set up, heating a pint or less is generally not going to be providing on-call WVO at 170-ish. Further, the only real option is a thermaline which is coincidentially 30" long which is perfect for a straight away from the HE to the IP. Trying to wrap the TL on the injection lines is about impossible for me but fits nicely in one straight shot. Now, that is not the mythical solution either to get to 250F either, but you can count on another 10-20F, depending on the ambient temps.

I used to have a 30HE which was probably the most common HE out there. Fill it up, and then drain it out and add 10%. Assuming that is your volume, the om617.9XX fuel system will blast thru that amount in less than 30 seconds. Assuming no closed loop system, calculate one's heat loss going from the fuel tank to the engine and back.

So, in the WVO community, everyone has their own flavor and "best" ways of doing things which is why WVO is truly a personalized modification and preference. However, some things are subject to the rules and laws of physics. Heat transfer, heat loss, et cet., will be the same in my system as well as yours. Who knows, my last system was supposedly perfecto but I changed it after a few years. Maybe a Greazzer 3.0 down the road.

Finally, it's done. Cleaned inside and out, coated with POR-15, new seals, and ready for install. Once I get my driveshaft spin-balanced, I should be able to install the 2:65 LSD this upcoming weekend. So far, so good ...

I wonder if a small HE could be used to slightly heat WMO to thin it out a bit so that it wouldn't have to be thinned with ATF/HF/RUG/Diesel/Kero?

Cool! That is a tall diff though. You planning a 3.0 turbodiesel?

At some point. I doubt its install will happen 2014. Projecting 160+ HP from my OM617.952. Right now, the REAL goal was the complete interior, sound proofing, completion of my WVO system, and a bunch of R&D projects and having all those issues wrapped up by May.

Instead, I got side tracked with this differential ... When that's done, I will be 3 weeks behind and $500 broker ... lol

The leather seat skins sound nice. Please keep us informed about how you like them. Does that place offer covers for the rear seat?
