heat exchanger

[(RIP) PLANK]

if you go to a car body repair shop and look at the paint scheme, all the paint's are mixed in plastic cups, thinners and all! you must have crap plastic cups :augie


having said that putting such a cocktail of weird and wonderfull things in my tank would never cross my mind, no wonder you're having issues mate!:thumb2

Never had any problems with chemicals in plastic cups :thumbs

The amount of non diesel i put in will & has been ok :thumbs

Should be out of diesel by the weekend so i'll have a look in the tank & look at the injectors & plugs :thumbs
Then neck it with diesel :thumbs

it would be interesting to photo the injectors and plugs, and then again after 100 miles on svo and see if there is any obvious changes? your thoughts?

Yeah defo :thumbs

I wish I'd photo'd the old stuff :doh especially the glow plugs as they looked like they'd been touched

Adz, i'm too much of a coward to do all this fuel experimenting, so hats off to you for giving it a go and not being embarrased to come back and tell us all the ups and downs depsite the critiscism you sometimes face.

you're our test pilot mate :thumbs

 

[Adz]

Thank-you :thumbs

I unfortunatley don't believe unless i try it :doh

Thankfully my M8 & I can pretty much do it all between the pair of us

Or should I say he comes to my rescue & thats another favour I o him :augie :lol

I have a diesel boff looking at playing around with the injector nozzle hole size :naughty

the next bit

I'm trying that out at the mo. I have to say the engine does seem smoother though it may be me wanting it to

One thing I cocked up on bearing in mind the talk on here about red diesel, I lobbed the two stroke in (I think it was auto lubes finest ) and then noticed the colour of it.................bright red :doh

I'll take a pic of mine during the week as i have 2 clear inlinr filters & yes it makes it red ok :lol

Mine definitely runs better in the sense that it seems smother :nenau

From the rebuild i done its still on pump diesel with 1 litre of 2 stroke oil & petrol to thin out the sun flower oil...
I'm down to 1/2 a tank & done over 200 miles

Here's the pic

next setp taken got the fuel line on today

any one see anything i should do.. as in have i missed any thing.
YES, whater side will do tomorrow afternoon

 

[xkalibre]

planning on doing this myself very soon - just wondering what size diameter's the fuel pipe and heater pipes are? - i'm assuming this is where your running the coolant from.

the only thing i've been recommended was to put some form of lagging on the fuel lines to keep the heat in - can get stuff from most diy places for it

will

 

[zippy656]

hi bud fuel line is 8mm

yep got that in hand for the lagging. heater pipes dont know yet as was sucking in to much are as teh PTFE tape didnt work, so getting so proper sealer later this week ive taken it all out now for a clean up before u ise the sealer. will post more pics as i get further along.

where are you getting you heat exchanger from?

 

[xkalibre]

i got my heat exchanger from ebay - it's similar to your but all inlets/outlets are on the same side - it's from a combi boiler.

not fitting mine unitl i done the water pump as its leaking a bit

will

 

[zippy656]

ill keep you posted.

got meself some proper jointing compound tonight.

so if dry will refit it all back this weekend.

WIll try http://www.oilybits.com/ tell him steve sent you with the T2.. hel has ALL the bits youll ever need. and KNOWS his stuff..

 

[zippy656]

here we go heat exchanger for the veggie oil in and working

veg oil

I'm glad i asked zippy thats the same system im gonna use, ive got a tdi now the td went last yr thats why i was asking about the renault filter to heat from start and fit a thermostat to h/e to turn off filter heater when hot, i,ll be starting mine when i get the h/e and fuel filter htr thanks for all the info good luck zippy.

TBH its a fag though and not really necessary - there are plenty on here (me included) that have run decent ratios of SVO with no modification at all. If you ever get an issue its with lumpy running at start up when you exceed 50/60% SVO in lower ambient temperatures and a heated filter isn't going to fix that because it takes a while to warm up. The proprietary ones you buy have a stat in anyway, and come either as a simple glowplug-based heater or the more sophisticated type that circulates coolant from the engine to maintain heat and cuts the glowplug out when that coolant reaches temperature.

Despite what anybody on this thread says, unless you want to run medium/high ratios of SVO in the very coldest winter months, all this stuff is pointless - and neither will a diesel/SVO mix do your engine any harm......plenty of folks with serious SVO mileage under their belts to prove it.

Remember these engines are seriously old diesel technology with none of your fancy common-rail or other modern stuff and will run on all sorts of shite. With advice from a couple of petrochemical scientist friends/relations I've regularly added anything from acetone, methylated spirits and white spirit through to neat alcohol to assess their (always positive) effect on performance and fuel economy with zero ill-effects. :naughty

Just an update,


Now 5 years later

Still running svo

Loving the savings l!

Yes I've had problems, nothing to do with eco running, just timing of adding diesel and new glow plugs
