Well, its been a journey .. lol.
The red is the somewhat short and sweet version. the black is the novel version.
The problem with running WMO on an older truck is you never know if it is the oil causing troubles, or something that would happen if running diesel any way. i have had many troubles, but most of them are because of my own ignorance.
long story short, i have had a bunch of trouble with the truck. Most of this trouble was Due to an ICP sensor that i cheaped out on long before i ever messed with the WMO. but i have fixed that problem.
Now i am having accelleration troubles with the truck. its dog slow. i believe this is due indirectly with the WMO, but not directly with the WMO. Example- The WMO could clog the in tank pick ups much faster than diesel will. The wmo will clog the catalytic converter much faster than diesel will.
here comes The bible update.
I have been having trouble with the truck for 5 months now and have hardly been driving it. When i first bought the truck it would buck while driving it, and it was horrible. so i set out checking sensors to see what would fix it. One of the first things i read is that if the ICP sensor has oil in the pigtail, it is bad, or will be there soon. Well mine had oil in the pigtail so i went to o rielly and bought a cheap 30$ ICP sensor instead of a 200$ ICP from IH. The bucking problem ended up bieng a CPS (cam position sensor) which 7.3's are notorious for. But every thing i could find about cps's said that the truck shut off, so thats why i was reluctant to buy one. But, from the get go it had a bad CPS, i bought one from ford (26$) and all was good. at least i thought.
ME CHEAPING OUT ON THAT 30$ ICP CAUSED ME LOTS OF HEADACHES, EXTRA $$ SPENT, AND TONS OF DOWNTIME FOR THE TRUCK BECAUSE OF ME WORKING ON IT, trying to fix other things besides the ICP.
now fast forward to when i started running WMO in october. slowly the truck started to develop this wierd thing where it would not want to start when hot. first it would happen at random, and it slowly and steadly became more of a normal thing untill the truck simply would be almost impossible to start when warm. so i thought the IPR valve was going bad. so i took apart the HPOP system (for the first time ) and also noticed that my non serviceable plug was leaking. well i lucked out and found this write up here about fixing it
This is how to repair the "non-serviceable" plug on the HPOP
I had oil in the valley, but with me running WMO for fuel, i was unsure if it was engine oil or fuel oil in the valley. I was getting horrible MPG, and it kinda smelled like gas in the valley, so i assumed fuel was leaking out of the mechanical fuel pump's weep hole in the valley. So i replaced the IPR (180$, bought the hpop seal kit, 70$, bought a new carter fuel pump (70$) and i put a tractor fuel filter attached to my radiator so i could also eliminate the possibility of the stock fuel filter leaking into my valley.
I got it all back together and the thing still had oil in the valley. It also appeared to be leaking from the oil cooler mounted on the side of the block. So i bought a oilcooler reseal kit (65$) and set out to fix that. Well after a week of driving it, i had oil in my coolant and vice versa. So i then had to take it off again, reseal it, and re put it back onto the truck. Finally, i did not have water mixing with my coolant. But i still had oil in the valley, and the truck was still a ***** to start when warm.
So i took the HPOP off again thinking it was leaking from the base plate. i got this "grape jelly stuff" loctite brand, from a buddy that works at IH and i made sure to seal up every possible leaking part for the HP system. While the HPOP was off, i ran across something on the internet talking about high mileage 7.3's with bad injector o rings will have trouble hot starting because the high pressure oil leaks past the injectors into the cylinder. Then you have to build pressure while cranking to get the thing to start. so i also bought all new injector o rings , pulled the injectors and put the orings on.
After getting it all back together i start it up and take it for a ride and the damn thing still has oil in the valley, and the damn thing still wont start when hot. I then start checking for leaks very carefully with a flashlight, and i realize that some oil is coming from the ICP sensor. Call me an idiot, but It is very hard to realize this, because directly under the ICP is a bracket that will not allow you to see oil leaking from the sensor. The icp is also in such a magical place that it will leak and fill up the valley directly under the HPOP, and it will leak down the front of the block, onto the oil cooler. So this one crappy sensor leaking caused me 2.5 months of headache.
After that, i replaced the ICP with the expensive one from IH, 200$ (because it has gold protecting the contacts lol)... and my leaks have completely stopped and the truck starts fine when hot now. So that chapter is over with, hopefully.
since i have replaced the sensor, i have not ran WMO in the truck. i have decided to get the truck running great, with a tuner on D2 before i play with the oil any more.
Now i have been driving it for a couple weeks and the dang thing just starts to get very slow. i was having a very hard time getting up to speed just to get on the freeway. so i am thinking its either clogged "sock" filter in the tank, or my CAT is clogged from burning all that WMO. I put a fuel pressure gauge on the truck and BAM my fuel pressure at idle is 65, but its dropping to 30psi under a load at full throttle. So tomorrow, i am pulling the bed and inspecting the tanks to see what i can find. Also, i am going to order an exhaust tomorrow because its going to be much easier to install with the bed off than on. trying to knock two birds with one stone, kinda.
in the mean time, also i have fixed the AC on the truck, replaced the spider gears in the truck due to drivetrain slop. Welded up all the holes in the roof of the cab because of the PO having a Brow and it getting ripped off. which caused ripping the screws out and placing holes in the roof that created a wonderful whistling sound @65mph. And i ran surgical latex tubing through the front door seals to try and get rid of some of the road noise. I also have welded plates to the doors to accept Chevrolet tow mirrors onto the doors. As you can see i have been busy, and i have not given up on the truck one bit.
This WMO thing is one big experiment for me, but i think it will work. i just need to get the supporting mods for it first before i start to play with it agian. I also have bought a centrifuge to produce high quality fuel. I tried to get the filters to work, but even with the amount of filters i had, i still had water, and gunk in my end process fuel.
on the plus side, back when i worked at the oil change shop, we actually had a guy come in with an 05 excursion with a 12v in it. he worked for an excavation company and he said he had ran nearly every diesel he owned off of 80%W85 and 20%D2. He said the exhaust stunk, the engines smoked, and he had people tell him that his EX was about to blow up constantly because of the smoke, but he has been doing it for years. He is the one who convinced me to get a centrifuge.
