Yeah inside of the tank looks like that pic ive seen in your thread, nicely protected from rust :lol
Think i could consider svo in the future once things like fphe n heated filter was in place. Its just so cheap atm with the waste veg that even with some diesel an petrol chucked in its only about £30 to fill her up!

You'll constantly be fighting a losing battle with WVO

I've lived and breathed that life mate and it's no good, SVO is the way forward :thumb2
 
Later that day I had place to be so off I went. The intermittant power loss croped up but I didnt have time to stop n look so pushed on. Now the fault was getting worse struggling to rev, juddering at low speeds, eml flashing on and off then staying. So i though why not just drive along foot to floor and see what happens. It took ages but with revs stuck at about 2k my speed slowly, very slowly started to climb. I eventually hit 50 mph where the engine light went off and it sprang to life and pulled hard all the way to edline. After that it was like a different car back to how it should behave. At home it had stored a fault code no 21. Spent the eve reading about what this could mean from issues with them ranging from ckp, to no1 injector, shoddy valve in the return banjo or air.
Next morning went to go out for some supplies, turned the key she fired but running very rough! Having issue ls trying to idle nearly stalling. Managed to dash under the bonnet and grab this pic.
Looks like a bubble bath i the filter!

You've got a blockage mate plain and simple, been there seen that!!!!

Look at the state of the crap in that filter!!!!! How many Microns are you filtering your Oil down to? I used to do twice through a 1 Micron then a boil in a 200l drum with an M67 immersion heater to get any suspended water out of it.

It looks like you're filtering through a jumper :eek:
 
In my mind I new air was getting in somewhere so that night I set to find out where from.
First place was the tank as that was the last I touched. Soon as the cover was off I could see fuel in the same place I found it last time. I can of forgetten to tighten the bolts as I checked and cleaned them when it was off last week. Two of the bolts could be turned by hand on the side the fuel had leaked out but the bolts just kept spinning. Some grips and wrestling later I managed to pul them out and Ive new had bolts do this before. You can see the thread is completely stripped and i have two smooth bolts? They were stuck in good but unable to be tightened or loosened. Once out I luckily had some nuts n bolts that I could use to get the sender to seal good and properly.
This morning it was like a different car, great throttle response, no lumpiness through the lower rev range, no blips n eml lights under load when cold. So finger crossed this time, again :clap

Phew!!!! That's a result then!!!

Last time I was getting bubbles and foam like that I had connifers and leaves stuck in the swirl chamber.

Keep an eye on it, that filter should be fuller than that too, has the level risen again since replacing the bolts?
 
Probably do have/had somekind of blockage thats what it felt like. Filter down to 1 micron at ambient temps. So i guess im just gonna have to try n check areas where blockages can happen and clean everything possible.
 
Yep the level has risen but that is something i was considering as a low level would say blockage upstream of filter? Seems to fill up on idle on the drive but that was the lowest id ever seen it.

Have you got enough slack in the pipes to turn the filter upside down while it's running, that should start to fill it back up to it's normal level then.

I'd probably swap that filter for starters, have you had the swirl chamber apart yet from the pickup unit? It was only when I removed the bucket that I realised the extent of the blockage. I had to fish the leaves out with a wire coat hanger
 
Will try the upside down trick. I think all that crap in the filter is from when I had the sender and chamber out. They got a good wash in hot soapy water then blow dried. Blated air through the lines on the sender too. So im guess all the little bits of crap that I couldnt get out are now loose and heading down the lin.

That's good then I suppose, maybe leave it in a while longer then get a new one in there. :thumb2
 
Got myself a new stereo just a cheap ebay job from china. Will keep me going for the time being.

The beast has been running very well for a week since sealing up the tank, but since yesterday morning im back to loss of power, eml flicking on then off with a stutter at certain revs. She will rev freely but theres no pull. When the stutter happens with the light revs will stay where they are and the accelerator seems to make to difference for those seconds.
I went back to the tank. Replaced the existing bolts with some others so hopefully I can tick that off the list as a potential cause.
Reading codes im getting 21 so will re check the injector as per workshop manual tonight. Its a shame she was running so nicely. So back to some fault finding.

Welcome to club EML 21 :thumb2

It's a lonely place mate, I'm the only regular :lol :lol

My issue is due to a perished head seal on the IP which has been cause by running straight vegetable oil and has caused the pump to leak :doh

I'm still saying you have a blockage either in a banjo filter that may have blocked or been missed, first thing I would do now is get a fresh jerry can or container of Diesel and rest it in the engine bay, get 2 lengths of clear pipe and totally bypass the filter, fuel lines, sender unit, pickup pipes swirl chamber and tank.

You should be able to bungee cord it in place in the engine bay otherwise if you have enough length of pipe you could put the can in the passengers footwell and run the pipe into the truck through the passengers side window.

Go for a careful drive and see if the car shows the same faults, if it doesn't all you have proved here is that your injectors, injector pump and Crankshaft Position Sensor are good which are nightmare/expensive jobs, if all's good then start to re-introduce the other parts back into the mix and see if you can find the problematic component :thumb2
 
Haha sounds like a pretty exclusive club to be in.

Im hoping its something straight forward as after fixing that tank it was running great. Have changed the fuel filter last night and this morning there is no crap build up when i got to work.

So when you you get the code 21 do you experience a loss in power? Ie the code has flashed, eml goes away but im still down on power. So revs climb but nothing there.

Seems ok just cruising about so atleast its useable for the time being.

I know panelbeater had changed the pipework from the tank to the engine bay. Looks like copper of some sort and is maybe 10mm diameter.
Im going to try and blow through the lines to the engine and see if thats clogged an double check all the hose connections. Also take a look for this mini filter, although PB may have already removed it in the past. Is the mini filter on the feed to the ip?

So if I rig a seperate container to temporarily run, I take it the hose goes from jerry can direct to ip? Now should I run the return into the same can or just leave the return going to tank. An one final question what size hose is the connection to ip?

Hopefully I can find some decent hose locally so I can get checking straight away.

Any local motor factors worth their salt will sell you hose by the metre, I wan't to say that it's 8MM I/D but best to check as I could be wrong.

I would run the return back into the same Jerry can if you plan on doing a significant distance, otherwise you should be alright if you're just going round the block.

If the pipework he's used was Copper this could be your problem, over time copper work hardens and can crack, I did hours and hours of research on this and seen examples of cars that had cracked the copper usually where it was secured in place onto the chassis or body. If this has happened you could be drawing in air which could manifest itself the way your problems have. Ideally you want Kunnifer which is the stuff I used as it is perfect for this application.

I persistently just get the EML now even once I've cleared the codes, always comes back with 21 and nothing else. I have a spare injector pump sat on the workbench ready to go on the car when I have a few hours to take it apart and fit some new Viton seals in replacement for the rubber ones which perish with veg use.

I don't lose any power and my truck revs freely to the redline but it does feel like it's getting slower and slower top end wise now, it's certainly starting to fail and wont be replaced until it finally goes, that way I have a nice ballpark figure to go on first hand when people ask how long can you run straight oil with no diesel on a Bosch Terrano pump :naughty

I hope the issue you have doesn't turn out to be the new pump that Panelbeater has fitted :eek: Although given the issues you already found with it hanging off I'd give it all a once over again and hope it's OK :bow
 
I have to ask as well, when you had the sender unit out of the tank, did you pull the white swirl chamber apart from the pickup pipe exposing the internals and the spring etc?

That's where mine was blocked on the Maverick and gave the same kind of stop start stop start symptoms as yours until I figured out what was going on and fished the leaves and conifer needles out of all the orifices they were trapped in

If the swirl chamber is that cup looking item then yes, had it all off and cleaned anything I could.

Gonna pressume bloackage somewhere in the line for the moment and check everything I can in relation to it.
Hopefully its not the pump but I guess im looking to run veg long term then replacing the seals on them is needed at sometime in its life.

So when looking over the pump just signs of weepage or build up of veg?

Got plenty I want to do with this beast but getting it running spot on is number one priority at the moment.

Don't let it scare you mate, these trucks are stupidly easy in comparison to other junk out there, we'll get you there with it :thumb2

Have a look in here and do some reading :thumb2

Here's the Kunnifer I used :naughty

Got out of work late so everywhere was closed so no chance of getting hoses.
I did manage to get underneath and have a look about thought. This is what I found. Best angle I could get but it does look like quite a restriction in the flesh.
I clearly dislodged loads of built up rubbish when I took the tank apart as it was all in the filter. Im guessing that with the kinked pipe I got a blockage so when the temp drops with thick veg oil its too much. Makes sense in my mind as at low revs it rolls alot fine but with my foot down the juice cant get to where it needs to be? You will have to excuse the scabbiness of her underside as shes long overdue due a good scrub n some maintenance:D
Got some new hoses ordered an they are on there way by the weekend so I can try running from a jerry can and replace the flow and return to the ip.
