dogstar....

thanks for the reply...couple more questions for you....

did this seepage start after the B100?
that's the 2H motor?
how many gallons of BD would you say you've put through the IP?
What's your source for BD? homebrew? world energy/pacific BD?

this is really an interesting issue for me. All the issues I've ever seen with BD and seals/hoses have taken 10k+ miles / years to become an issue. This observation is also true for a friend who has been in the BD research/design/brew business for 20+ years. I'm really curious about these Toy pumps and have posted in the past regarding the IP and what type of seals they use. The best info I was able to summon up was that 85/86 was the years they might have started using Viton in the IP.

To all you biodieselers...

What kind of kooks are you, tryna say vegetables will make my truck go?

Just kidding. Just a quick note to thank ya'll for making an effort to affect some type of change and still manage to eat your cake too. I think it's fair to say most U.S. Cruiserheads, myself included, are envious of those of you with oilburners, even moreso when you're almost climate-neutral and can get by on .70 worth of fuel.

You bastards.
 
2H motor
about 300 gallons or so of pacific
only had the truck a few months and started running bio the moment i got into cali coming back from bc where i got it,looked the truck over really good when i first got it and didnt see any thing wrong at all-everything was real clean
after changing out the fuel filter i splilled a little bio below it and noticed that even after you clean it up you can kind of still tell it was there ,leaves a oily residue that dirt sticks to
i drive alot and after about 3 months and 300 or so gallons of bio it looks like bio has started seeping out of the ip at most cracks and the dust and dirt has started to stick to it (i live 10mi up a dusty poorly maintained mountain road)
definatily didnt look like that before
unfortunatly i dont have a barn or a garage built yet so i have to wait until it stops raining here before i can investigate more until then i just switched back to diesel and have been having fun with my new BJ70 which is never going to see bio and going to go to svo as soon as i get the cash

...soon come
 
They say most rubber after '91 or so is biodiesel-proof which I'm not sure if that is true or not but that is what I have heard. I am no expert but I know that biodiesel is much cleaner and will clean the gunk and sludge out of most stuff, so my thought it that maybe you cleaned some junk out of your pump??
 
I have a 2H motor and have been running 100% BD for 6 months / 5000 miles. I've not noticed any change around the injectors. A while ago I changed the fuel filter and managed to get an air lock. I cracked open the injectors and cranked the engine to get the fuel flowing again. Afterwards, one injector was leaking but I just tightened it a little more and all was OK. I wouldn't change to SVO personally, I doubt BD would have corroded any seals in your pump in such a short period of time. Tighten the leaking injectors and don't worry.
 
after a thorough inspection the seepage seems to be mostly on the fuel feed pump and the govener case housing and the base of 2 injectors where they go into the IP
i have wiped away most of the gunk and plan to go back to bio and keep a close eye on it to see if it comes back or if it was some random fluke that has gotten me worked up
i will keep yall posted
thanks for all of the input,suggestions,and concerns

Bumping up this post--wealth of info. Maybe admin will make it a sticky? BioDiesel FAQ?

I live in canada and drive Bj60 3B.After reading forum on the bio diesel i had to look into it and like you guys have said the big problem seems to be the cold weather.It's a real shame i wish i could try it in the my rig.But the more i think about this biodiesel and the vegetable i wonder on how many mining companies have entertained the thought of using this fuel source.In an underground application the health benefits alone for their employees would make it well worth while.
I work for BHpbilliton but once again i work and live in canada and the weather will not permit the use of this alternative fuel but in a country such as Australia why not?
I know that diesels are equiped with scrubers for the underground applications but if you ever had the chance to go underground the diesel exhaust is very very noticable.
If anyone has any information that pertains to this please share.Thanks

You can mix Bio Diesel with petro diesel in any ratio. I run 100% BD in the summer and 80/20 in the winter. In our coldest spells (-5) I may go to 70/30. My guess is that you could find a blend that will work for you at much lower temperatures but I would ask on a biodiesel forum and see who has experience of this.
 
Bj60

Well after only having my BJ70 for a couple months I found what looks to be a really sweet BJ60 that I will be driving back to California next week:

http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=4503752156

Anyone with any BJ60 specific advice for me, biodiesel or otherwise is appreciated. I am assuming I will only have to swap out the fiel lines again for Viton...

I also plan on selling my 70 once my 60 is here...
 
Congrats! Let us know about the '70 when you are ready to sell. I am in the market, though close to a deal on an 83 BJ42.

Hello all, just want to bump up this thread and find out if anyone else has had problems with seals/rubber parts of Injector Pumps degrading with Biodiesel. I'm a newbie so pardon me if my questions seem obvious, but am just trying to find out as much as possible about 2H engines running biodiesel.

dogstar, I emailed you seperately but will post here too....did your Injector Pump issues get worse? Did you do the SVO conversion? please let us know.
 
A few months back I saw the filler tube from a BJ42 that is running bio-diesel. It was pooched. Don't know what other lines the mechanic changed at that time.

What exactly do you mean by "pooched" Greg? Deteriorated by the bioD?

Yes, by the biodiesel. The engine came out of a BJ70, and replaced a B. Less then one year later it was back in the shop and the fuel filler hose (steel/nylon cording, wrapped in whatever the rubber compund is) was pooched. The rubber was degrading so you could see the cords (I made the mistake of touching the filler hose and had a hard time getting the black goo off). One line was also changed either to or from the fuel filter as it was weeping, and the rubber lines from the tank and to the feed pump were changed as well. I talked to the mechanic this morning real quick, did not get all the info, however I know the engine, and know how long it was in the truck.

I know the owner had been running biodiesel for a while in the B, but have no idea how long, so can not tell you how long the filler hose lasted. I do know the 3B was in the truck less then a year, and that line (forget if it was from the lift pump to the filter, or filter to the injection pump) one line was weeping and had to be changed.

I was at a lecture today about biodiesel and found out that B20 will not harm rubber, only b1/b100 will.

What's B1. B100 would be 100%? Not sure what this fellow is running (he lives in the NW USA), however I know it is biosiesel, not WVO.

Thanks
