Oh problems problems - road trip from hell - need ideas

[thehanko]

OK,

so to set the scene. 89 ln 106 turbo hilux running a heated 50:50 oil mix.

left sydney at 5pm wednesday night - drove 600km north to a place called dorrigo.

the car was fine though it did seem to have more power at some times compared to others.

stayed at a mates house, got up the following morning and the car was a little hesitant to start. drove 200m and lost all power - blocked fuel filter.

I had a spare so we replaced that - the primer pump didnt seem to do anything so i primed it by mouth - yuk!

all good - thought it might have been a bad batch of oil so filled up with pure diesel.

drove out bush for two days and a few hundred k's of dirt and whitewater kayaking - awsome by the way

Then the brakes felt sloppy. thought i can limp back to dorrigo. then got a rattle in the front left. so we stopped.

The brake caliper had rattled loose and the wheel bearing had play in it.

Pulled the hub down the lock washer was in place for the bearing so not sure how it loosened - perhaps it has collapsed. re tightened it and i will pull it down on monday.

tightened the one remaining bolt on the brake caliper and limped into dorrigo. got there at 5pm friday evening and found the machine shop still open for a new caliper bolt.

Then drove to sydney gradually mixing veg oil back in with diesel.

Got to about gosford and it felt like the filter was blocked again!

The primer pump was vacumed down. pulled the filter out and emptied it all etc etc. again the primer pump was useless.

eventually having had half the fuel lines off checking for blockages etc. got it going again at full power.

10min later blocked again, pump was vacummed down etc.

lots of stuffing around not sure what was stopping fuel, got it going eventually.

3 hours later, im on the side of the road and couldnt blow through the fuel line anymore. in the end i found it was the pick up line that was blocked not the filter.

so i switched the supply line and return line at the fuel tank - re primed it and off we went. (note it was still flowing through the filter as per normal)

then got to the point the power died, swithed the fuel lines back and off we went and got the last 10k home.

The most infuriating night of my life!

What do you think? just lote of crap in the tank? Im planning to take the sender out of the tank and check its not clogged, then drop the tank out and drain and flush it out as thats all i can really think of.

Then new brake pads and bearings. even though that bearing is only 20,000 k old.

oh and rolled into bed at 6am

I`d say the in-take filter has come off the pickup and its sucking crap in the line.
You should be able to take the supply line off at the primer and remove the fuel cap. Then just using your mouth blow all the fuel back down the supply line and back into the tank, you`ll hear the bubbles in the tank when its free. If you don`t remove the fuel cap you`ll find it heeps harder to blow the fuel back.

I used to have a small stone in the bottom of my tank and it used to get stuck in the end of the pickup. A quick blow down the line and it would be sweet again for months Was about 4 years before I finally pulled the tank out to get the stone out

Oh and I never used the primer thingy anyway, just turn the key and it`ll fire, the 2.8`s are good for sucking the fuel in without priming. Well mine was anyway

thanks mate, I had figured either the filter on the intake was off or clogged, but i cant currently blow anything back through it even with the cap off, so i think i will pull the pick up out of the tank and have a good look. probably just too full of crap to blow back out.

thanks again.

any suggestions on how the bearings can loosen off without the lock washer comming undone? the only think i can think off is the bearins collapsed but im not a bearing expert.

[Sic Lux]

Probaly normal wear and tear if the load on the bearing is set right lock washer is in good condition and lock nut is done up tight nothing will have moved.

Couple of things....bio or veg oil cleans tqnks that have buildup of diesel crap in them...if you buy from servo, you get the crap out of their tank aswell as what will come out of yours to filter....inside your tank, the suction line has a plastic filter....it will be blocked when you remove it...
The wheel bearing is most probably due to it not being tight enough to begin with....the inner race spins and wears the spindle. Spec says tension down to whatever...20nm or so..it seems too tight if your not used to doing them.

What flow was the Nymbo? what section did you do?

[thehanko]

What flow was the Nymbo? what section did you do?

did platy to cod hole twice - we were planning to do platy to cod hole then cod hole to junction - but then looked at the map and it was a 150km car shuffle x 2. and we had to drive back to sydney after the trip, so we decided to do the top section again.

1.1 at the nymboida town guage (the one that shows up online) and .55 at the platapus manual guage.

Was worried it was to low when we saw the platapus guage, but it was great, just the right height to ensure we could run everything, i grew up there but hadnt paddled it since 2000.

2 of us ran everything, the other 2 walked devils and rock bar.

I will have footage this weekend so i will post a link.

[thehanko]

So the car,

pulled out the bearings they seem fine. re tightened them and will re check in a week or so.

The brakes - new pads and i gotta say the toyota system for replacing pads is brilliant!

The fuel system - drained the tank, but didnt remove it just used the drain bung and tilted the tank to try to get it all out and filtered its contents fluched it through again and re filtered a few times.

Then pulled the fuel pick up out - the filter in the tank was intact but very clogged. Ordered a new one from toyota (no one made afermarket that i found) $26. but they have to order it in. so i removed the pick up filter and put an extra filter in line - just a super cheap auto $3 job.

Holy shite! in the first 15 min it had filtered out 1/2 a teaspoon of crap - not the sort of crap that has come from the oil thats for sure. so im going to leave this filter in for a few tanks and try to catch as much of this as possible and run the tank as low as i canb each time to try to pick up the gunk in the cheap filter.

will keep you posted - thanks for the help.

ha ha!!!
suck shit ASSHOLE!
that's what you get for being a tight ass!

millions of diesel powered engines in the world run just fine on DIESEL and don't block filters,lines,pickups or pumps!

so WHY would you put vege oil crap in your tank?

are you that tight?

or just fucin CLUELESS?

firstly, learn to spell. an ass is a sub-family of donkey. donkeyhole is not an insult, it just makes you look like a fool.

what do you think diesel engines were originally made to run on? peanut oil mate.

the reason bio-diesel has a tendency to block filters is because it actually CLEANS the crap outa ya tank and lines that accumulated from using normal diesel.

he might not be tight, he might just realise that he is doing the environment a favor by using a bio-fuel.

i think that it is YOU who is the clueless one. do some research then come back and join in this discussion. untill then, keep ya pointless comments to yourself/

[thehanko]

Funny how some people feel the need to get involved in things which in no way concern them, yet they are so concerned

sigh!

Anyway - its interesting the stuff im collecting in the clear filter, its like black flakes - a bit like paint peeling or rust flakes, but its neither of those.

might have just been a really bad tank of diesel perhaps? what is the diesel residue which is cleaned out like? sludgy or hard?

The car is running fine now - just interested now from a knowledge point of view.

I just got given a work shop manual for my birthday!!!

58nm of torque to tighten the front wheel bearings.

so effectively for we folk without a torque wrench (perhaps christmas)

6kg of weight on the end of a 1m bar, 12kg or weight on the end of a 50cm bar.

or in the case of my little 3/8 ratchet (which fits the hub nut socket) which is only 25cm long its about 25kg. which im sure is more force than i would have used initially.

so i guess i should have got the manual earlier - but alls well that ends well.

Have put diesel conditioner in a tank of pure diesel and left the extra filter in place, and it continues to collect crap, so i think ive got a few tank fulls to go where i will carry and extra filter then it should be right.

I was kind of suprised a mod hadnt come through, erased all his comments and locked him out.

yeah have a look at his "post made by user" link in his profile, theres only about 2 posts that dont have some form of abuse or inapropriate comment in them... seems like a silly little teenager on a power trip, but from previous posts he seems to be a fair bit older (mentioned that he has installed diffs in his job, sugests late 20's at least...) poor bastard prob doesnt even realise how stupid he looks

yeah made me think of kids in a group around the key board. i bet if he used to work on diffs (big if) he wouldnt of got many customers getting past his welcoming demeaner

'hi asshole, do you want me to abuse you or fix your diff'?

Im being serious here- but my chip frier at home gets little black flakes of crap in it from time to time- I like to call them BCB's- Burnt Crispy Bits!

maybe a dud load of oil that slipped thru the filter?

its amazing how much shit ends up in your tank tho- When i put the LR tank into the lux, it was flushed and cleaned spotlessly inside.

When i pulled it out again for the rebuild- it had done about 1.5yrs of service, it had at least a tablespoon sized pile of just...crap... in it- Bits of dirt, flakes of metal, hair, all sorts of gunK!

[thehanko]

yeah.

its possible that early on when i was learning i could have stuffed up, but not sure why its only just become a problem.

my new filtration method is pretty bomb proof, so i dont think its from that, but who knows.

the stuff collecting in the extra filter seems to have slowed down, so when this tank is run through i reccon it might be ok.

its not blocking the tiny little filter so i think its just about right.

Try visiting http://www.biofuelsforum.com/svo_users/ for WVO specific advice.

WVO does not clean out fuel tanks, not much anyway. Biodiesel does, which although sourced from the same product, they are different fuels.

I suggest, no, highly recommend that you do a couple of things.

One is to completely remove the in tank filter.
Also completely remove the $2 plastic filter on the suction side

Install a 60 to 100 micron cleanable agricultural filter after the fuel tank and before your primer pump so if you get more crud in the tank, then you can change the filter easily.

Most WVO clogging problems are cured by better home filtration. Most users filter to 5 micron or less, with 1 micron being the favourite. Up flow settling systems are becoming popular and the affect of time and gravity cleans the oil very nicely.

The cheap filters clog too easily and create restriction on your suction line where you don't want it. Many problems are caused by too much restriction on the suction side - such as cavitation and fuel starvation.

Blends can result in algae running rampant. Add a biocide as a matter of course when you are blending. Algae blocks filters and coats tanks in slime. Blending with 15% ULP seems to have less of a problem with algae, but be careful with heating a blend with ULP in it - you can get major pre-detonation problems that will rumble your soul.

Tim

[thehanko]

Cheers mate,

my fitration set up is to 5 micron and im pretty confident about that side of things.

Your right about the cheap filters being to restrictive. I have found i can run a cheap prefilter when running only diesel, however as soon as there is a blend it simply doesnt keep up.

It seems to be running really well again now so i think ive solved this issue, however i will be running the algae treatment in the future and have put a new in tank filter in again now.

Thanks
