Diesel leaking pipe

Casper · 2020-03-12 17:04:47

Best get a glamorous friend. One to crack open injector and other to crank engine. When you get a good flow of fuel should stop and tighten injector. Do this with the four of them. I need to do that every time i change a fuel filter on my Convoy. The ring that holds the fuel filter cap may be your issue also. Lots of cheap new ones dont seal properly so if you also have a new one of them try the old one.

lincolnexpert · 2020-03-12 18:14:35

Thanks for that Casper. It's starting now as long as it's primed so the leak at the housing seems to be causing the fuel to draw back. I reckon the one way valve will help but i'm definitely going to have to buy another housing lid. Tried two different rings(clamps) and made no difference.
If I hadn't broken the housing lid taking the egr off i'd be all set now sad

lincolnexpert · 2020-03-12 18:17:22

I've just seen this and think i'll do the same https://www.youtube.com/watch?v=KYjev4ea_aU

Casper · 2020-03-12 18:25:55

Looks a nice cheap fix. At least you also now know you have not buggered the engine up. Mind and block them vacuum pipes. Im sure i am getting closer to 40mpg rather than my usual 35.

lincolnexpert · 2020-03-12 18:38:02

Yes it was a relief not hearing any rattles. It's only done 107k and never let me down. Did you just cut the heads off the bolts to fit into the vacuum pipes?

Casper · 2020-03-12 18:43:02

No just pull the rubber tubes off and stick an M6 bolt in them and a bit tape to hold in place. I dare say folding tubes over and tape up will do the same job but you want it to be easy to put back for next MOT day. Im running with bolts for now and if no issues after a few month ill put something in the tubes like a rubber sealant then slide them back on so it all looks EGR legit.

lincolnexpert · 2020-03-12 19:21:31

Ah okay so at the egr end you've just taped the holes up? like the idea of using a blob of sealant

As kenbw2 says crack open an injector ......
No need to remove inlet ....

First injector on O/s (Drivers side) is clear to crack open with a 17mm spanner I beleive ...........
Don't remove nut just slacken it enough to leak ..... When a bunch of air is purged aand the van either fires and runs or is just about too this is when it's leaking Diesel profusely tighten nut and stop the leaking you should be job done and going now..........

I can see what you mean but I put the seal on the lid too........... the origonals can leak also.....
Try reseatting it see if it improves ..............

BTW would this have been a better option too see (not the price)..............

Hi Vaz, went out this morning and she fired straight up so all sorted bar the weeping from fuel housing lid. I did see that genuine housing but funds at the moment are a bit tight so after some research I ordered a PURFLUX one. Apparently it is a trusted make and even Peugeot use their filters.
They aren't as cheap as the crappy Chinese ones but one seller has a few for £29.99. Usually around £80
Link here if anyone interested https://www.ebay.co.uk/itm/Brand-New-Pu … 2749.l2649
When I get it i'll let you know if there should be a seal lower down as well.
Good to know that you only have to open one injector and not all of them to purge.

vaz2121 · 2020-03-13 11:59:59

I've done the same thing .......
Changed a filter ..... Wouldn't start or started for a bit and stopped... been to lazy to use primer pump ... So cracked an injector as described........

Good to hear your up and running ...... DW8's are about as simple and a slug of a diesel as left out there ......But like every thing can leave you stumped at times with what their doing......

Purflux, Febi and there's another that escapes me just now are decent quality parts .........
There's quite a few other branded names I'd use as well ..... Trouble is a lot of their stuff is made in China also now ........... (You ever looked to see where that expensive {apple product} Ipad etc was put together)

Some {most} of those knock off China products are atrocious and give the aftermarket a bad name ....{But we keep buying that sh**e}
Has any one else noticed that cheap sh**e we've bought from China is either not arriving (ever) or has massive delays over and above long lead times {Or is it just me}

I know what you mean about Slug! Although she Happily got up to Glentrool at a constant 70 last Friday....apart from the hills on the A75! Oh and coming home at 56 on the back of a truck. I used to get 80-85 quite easily out of a Berlingo(much lighter) I had and my old C15 would do 85-90 but they weigh nothing. Just wish I had a 1.9 TD but then turbo's bring all sorts of grief don't they.
Yes everything is made in China now. I have heard bad things said about Bosch parts now they are made there. I guess if you go for one of the bigger names they must at least have better quality control.
I'm waiting on a couple of non car bits from China that seem to be taking forever too. Maybe it's the Corvid 19 holding it up.

vaz2121 · 2020-03-13 15:06:15

Yes Turbo's can give lots of grief as can DW8's but Usually that's through abuse and/or lack of Maitntenance...........[both]
The more toys the more that can fail...........
Turbo's on diesels are not to be scared of........ All this computor control and lighter cheaper materials used now-a-days are for a Luddite like me...........
{Gone are the days where making it a Heavy duty version/car derived vans were beefed up for working duties [Squadie proof]}
Without going over lots of history - The hows,where and why's.......... I've kept my partners after it's replacement and it on retirement duties at now 20yr old ...A 306 with a early DW8 and running sweet as a nut @ 212,000mls and although the best I ever averaged on a tank with it was 57MPG I still get at least 10MPG on average better than the Van with less than half the milage on it...(I prefer driving it to "The 4yr old car I've got with less than 13,000mls on it")..... Weight and gearing of van has a lot to answer for unless you have a 2.0HDI........

I've never driven a Berlingo with a DW8 in it but have been passenger in an eary version same age or even a year older than the 306..........

I did have a very Brief affair with a C15 or Champ as it was called......
Quite a late very low mileage lightly used van being 2004...........This before I got the Dispatch.........
It's issues of being to small and very basic with reglular window winder failures were passable/workable.......
It just seemed that everywhere had some kind of rot in it {Must have lived out side and done next to nothing in a harshish enviroment} ............

Yes ... I'm sure this Corvid 19 virus has everything to do with it........... Nevermind the Brexit fall out per-Say........We maybe better tighten the belt and brace ourselves for the next 3 years

lincolnexpert · 2020-03-13 15:28:23

The C15 Champ certainly liked to rust. Mine had more rot on it at 8 years old than my Expert does at 17. It was an 04 too. I see they are making good money now on ebay. The non power steering got too much for my Tendonitis but I do have a soft spot for them. My LDV Pilot with a DW8 Now that really was slow.
I know what you mean about Turbos. On my last Van(Astra) it was not so much the Turbo itself but all the Sensors linked to it that kept putting it in limp mode. It was nothing but grief.

70. Did you leave the handbrake on big_smile

Casper · 2020-03-13 16:07:18

I was going to get a pilot to convert but aye. The engine put me off so bought a Convoy. This was after i made a micro camper out a Pug Expert and took that to the Black Forrest. Converted the Convoy and got three years out of it before deciding i want larger so bought another Convoy but a coachsmith bus. Got a W/E away in the old convoy at the start of April then its up for sale. Shame as its been a great van.

90! I took mine on the Autobahn to see what it could do. Best I could do was 80...

I did see 90 on downhills with the wind behind me though!

Did i not talk to you before about this? I was thinking its a DW8/DW8B thing as i could only get 80 also on my older van. That picture was on the flat on the German A1 just east of Germanys Edinburgh.

lincolnexpert · 2020-03-13 19:15:29

90 yikes Blimey! Downhill? To be honest I've never tried but I can't see mine doing it on a flat road. The thing I find with them is the time it takes to wind them up. tickle the brakes and you lose all momentum lol.
I love Convoys. Had a 2.5 6 wheel ex Minibus done up as a Camper for a while. Only got rid as I moved somewhere with really limited roadside parking. I liked the Pilot I had but to be honest there didn't seem to be a lot more usable space then there is in the Expert. Had no end of grief with Kingpins and Clutch forks on that.
90 mph.....no wonder you're only getting 35mpg wink Have you done any tweaks apart from egr? I know there was a tweak you could do on Nissan Vanette/Cub pumps to get a bit more out of them

Casper · 2020-03-13 20:57:38

No hill and bog standard DW8B with EGR disabled. 35 seems to be the norm unless driving miss daisy but i do seem to be getting closer to 40 not. That is either the injector cleaner i was using or the EGR. I can highly recommend this (link) You dont actually but it wont do any harm using it till you run out and then treat the van to BP Ultimate once in a while.

https://www.ebay.co.uk/itm/HYDRA-Diesel … 2749.l2649

Yeah my convoy is an ex Minibus also but with the Transit 2.4 Duratorq engine.

lincolnexpert · 2020-03-14 00:19:34

Love the Van....and the Rottie! smile Lost my Girl a year ago. Miss her everyday.
I will have to give that Hydra stuff a go. What's the difference between the DW8 & 8B?

lincolnexpert · 2020-03-16 09:29:14

Just want to thank you all for your help and advice. Got her going yesterday and took her for a 15 mile test with no problems. No lasting damage and no leaks(so far) Don't think I would of been able to do it without your help.
I've binned the cheap Copy fuel housing lid. It just wouldn't seal/seat properly. Total waste of money and plastic. Another bit of cheap Chinese cr*p for the landfill!

Not a lot. around an extra 3BHP and an ecu is about all i can tell.

lincolnexpert · 2020-03-16 12:45:57

Spoke too soon. Went out this morning and wouldn't start. Tried priming it and fuel was leaking out of the primer quite bad. So I guess the seals had gone in it. Probably all the over enthusiastic pumping these past few days.
I'd only fitted the new Purflux housing lid as i'd cracked original and Chinese copy wouldn't seal. So I've just fitted the whole Purflux housing. seems okay so far also fitted new feed pipe I'd bought.
Before tightening the pipe up at the pump end I primed it till fuel came out to bleed it. Tightened it back up and starts fine. My only worry is this bolt & Union are tight but the whole thing moves around a bit. Before I changed the pipe I'm sure it didn't move. Is this normal?

Casper · 2020-03-16 12:54:42

If the sticking out bit that the fuel line is the same as a banjo bolt on bike braking systems then no it should not move. I would think you need a crush washer under it and over it then put the bolt in. Crush washers make the seal and tend to be copper.

Need to go work. Bit of luck someone will be along soon to help you more. Good luck

Thanks Casper. I have no idea to be honest. I'll take another look.
