Does your motorhome have black smoke when starting? It could be a simple matter of replacing the oil and air filter. It's such a simple procedure.
Did it fix you black smoke problem
Yes, changing the fuel and air filter seems to have fixed the black smoke issue, RV EU 16 Camper 👍👍
Thanks. Great to watch a good old school mechanic at work. You can't beat experience.
Thanks David. We really appreciate your comment 👍👍
Great video,I am replacing my fuel filter in the next week or so.because mine had not been changed on my Peugeot boxer Autocriuse.
Been looking around to see how,and have now been shown.thanks
Chris
Glad it helped, @chriscox1547 👍👍
changed the fuel filter today. thank you for making it easy!
I'm glad we could help, Matthew 👍👍
Thanks for the movie and the tip, i should do this on my Hymer B544 2005 next week.
No problem, Bengt-Åke Linder. I'm glad you found the video useful. I hope you get it sorted 👍👍
Great demo on replacing the fuel and air filters doing mine this week 👍
Thanks David and good luck with that. Glad we could help 👍👍
Hey up👍😂fantastic video sir👍you’ve inspired me to do all this
Myself to my hymer. Easy peasy 😁thank you. You’re a star🤩
Thanks Jay. Glad you of helped you out. Good luck with your maintenance and let us know how you get on.
Really helped me out thanks
Great news, @staneee4th487. I'm glad you found it useful👍👍
The diesel filter sensor is there to detect water in the system. Water is heavier than diesel so sinks to the bottom and can be drained away by undoing the sensor or the white cap at the bottom of the filter, hence the little drain port.
Keep an eye on that air filter. If it gets black fairly quickly, then the PCV valve is letting oil from the crankcase breather through into the filter. Normal engine wear I'm afraid causes that. More regular engine oil changes will slow down the wear slightly.
Thanks for Sleepy Cat Pictures. Great information.
@@HermanHitstheRoad Ta! the Disco 2 fuel filter is very similar. Had to change mine 'cos it started leaking!
Would that be a sign of worn out piston wrings? I get plenty of oil in my air filter
@@alexandreromao8410 If the oil is from the crankcase breather hose, or it could be a blocked PCV valve. Usually, yes.
@@sleepycatpictures1176 if the pcv was blocked the pressure would just build up on the crankcase correct?
I've seen cars with so much crankcase pressure the oil would just come out the dipstick.
thanks for great video
Glad you found it useful, Harri👍👍
Very helpful, time will tell how easy it is.but thanks
No problem. Thanks for commenting, @alistairwilson-fi7mv. I hope you find it simple?
What a pair of nuggets, as has been commented on, the centre o ring was left off the new filter and you really show fix any cracks in the air filter housing before re installing it. What is it aboutsome British mechanics, the state of his workshop and general demeanour really let the side down.
Alan, the o ring was removed before we fitted it. You can do amazing things with video editing. As for the workshop the covid lockdown sorted that out. How's your workshop?
@Alan Magee I disagree. I found this video very useful, it's great to see a good old-school mechanic at work. We don't all have a fitted-out workshop and I can relate to working on my van as in this video.
I'm glad you found the video useful, David. Thanks
It looks like you guys not forgot to put the inner / center rubber seal on the filter when installing (The one you put on the bin before priming it with fuel).
Haha. It does doesn't it? That's video editing for you - unintentionally of course
great well worth watching
Thanks John. Would this be a job you need to do during lockdown?
So did it need the white plastic clip for the middle seal or was it just to keep it together in the box?
It was to keep it in the box, @chocolateparsnip. It needs to be removed. I hope you found the video helpful.
These service videos, with explanations on how and why you are doing something, are quite useful.
How do you clean, wax, or otherwise beauty treat Herman? For me the roof is hard to clean and keep from collecting dirt and organic stuf.
Thanks Ari, I could make a video on how to clean the roof
Herman Hits the Road 👍🚐
Hi. Did you leave the senter rubber ring on the top of the filter, or did you put IT on the senter Axel? I tried with the senter rubber ring on the filter, but IT was hard to tighten by hand.
I think we put the sender rubber it on the filter. We also put the top/centre on the filter and screwed it in, @JohsFolkestad-v8w
Tengo la misma que tu. Te sigo desde tiempo
Google Translated your Spanish in to "I have the same as you. I follow you since time."
Thanks Juan, a long time subscriber then? Do you have a Hymer B564 as well? Do you have black smoke?
Herman Hits the Road. Tengo mismo modelo hymer b564 año 1998 con 204.000kms y SI todos estos motores en frío humean bastante
Herman Hits the Road por cierto me puedes poner referencias de los muelles y amortiguadores que montaste. Se ve muy bien, ¿es comodo?
That's great, Juan. How long have you had your B564? Does it have a name?
A diesel engine may produce grey smoke on starting but it shouldn't be black
Juan, yes the front shocks are very comfortable and firm. We've not tried them on a campsite yet. Here are the parts used. The SKU number is Coast Motorhomes own number:
Fiat Ducato Peugeot Boxer Citroen Relay Coil Spring Q18 1318989080 SKU 32080-32074
Monroe V4501 Van-Magnum Shock Absorber
Just wondering is this the 2.5 engine and if it is have you ever replaced the coolant as I am having trouble locating the engine block drain plug and also the bleeding screw when I begin to refill. Any help would be much appreciated. Thanks.
Hi Graham, it is the 2.5 diesel but I've never replaced the coolant. So, unfortunately I can't help you there. Have you tried asking on Classic Hymers Technical Facebook page? They are very helpful
@@HermanHitstheRoad hi thanks for the reply. No I haven't tried that yet but will do. I'm running out of options even the manual I have has no pictures or diagrams. Thanks for the help 👍
Hello again just been denied access to the classic hymer tec group as the engine is in a boxer oh well back to the drawing board. Thanks anyway.
Did you end up not using the inner rubber seal at all?
We did use it, Dave. It just looks that way in the edit. Hope you found the video useful
@@HermanHitstheRoad Yep, all your practical videos are really useful, thank you!
The white cap is for waterdrainage
Thanks for commenting, Paul
Hi,just another problem with my Peugeot boxer motorhome,I noticed a small diesel leak under the the engine looks like a seal may have gone or pipe problem any ideas.Chris
Hi Chris, I can't say without seeing it. Have you looked yourself? Where abouts is the leak coming from? If it's dripping then you should find out where it's coming from pronto
@@HermanHitstheRoad hi managed to get a mobile mechanic.he says it’s a seal at the bottom of the pump.Thanks so much for getting back to me.very much appreciated Chris
You're welcome 👍👍
black smoke is caused by diesel/fuel and blue smoke is engine oil .. dirty injectors and failed heater plugs often cause black smoke blue smoke is because the engine is burning engine oil, could be over filled, blocked breather, worn piston rings or turbo (if turbo model) unless something more serious.
Thanks for the advice Mr Grumpy. Are you a mechanic too?
ive just got a 2.0 litre jtd (2005) that i nearly ran out of diesel , since then its been momentarily hesitating at low speeds on acceleration so i guessed some crap from the fuel tank got into the filter , i replaced the fuel filter today but didnt fill it with diesel first like this guy did here , it started ok after 20 secs or so but its still hesitant like before. no better no worse .. , if its self bleed , why is it still showing signs air is in the system ? anyone? thanks
I don't know what it could be, @the dreamlikestatemusic. Maybe you've got a dodgy or blocked injector (assuming it has them) or something else is blocked. What is the most obvious thing it can be? Have you checked/replaced the air filter?
@@HermanHitstheRoad hi thanks it seems ok now
Great videos . How much is Herman’s road tax ?
Hi Preston, the road tax is £265
You never put that middle rubber washer on haha
We did, Jonathan but we didn't film doing it. Haha. Thanks for commenting 👍👍
Los amortiguadores que sujetan la cama están muy bajos
I think Google had a tough time translating your Spanish this time "The cushions that hold the bed are very low".
The shock absorbers on our motorhome that hold the bed up are OK. the bed squeaks a bit though.
Do you yours need replacing?
Los hidráulicos de la cama los cambié y perfecto
@@HermanHitstheRoad I bet it does, but as long as your wife is happy.
I camped next to a van once, they were at it like a couple of rabbits.
Dispose of the fuel properly...
“Not set fire to it and throw it at somebody?” - I mean... who says that sort of thing?
You should see our safety video, Nathan 😉🤣
You forgot the rubber seal of the diesel filter
Thanks Winston, but we didn't forget the seal. It only looks like we did due to the edit 👍👍
Check if your cambelt needs replacing ! The most important serviceable item on a vehicle ! If it snaps the engine smashes the pistons and valves thousands of pounds of damage !
Thanks Mark, we had the cambelt replaced about 3 years ago but we should check it out and maybe do a video on that too
@@HermanHitstheRoad I just googled it and motorhome website said ducato hymer every 3 years .a video would be great ! As an ex mechanic I'm always getting mine done slightly early .keep up your great content !
The end cap is for water 😂
? 🤷♂️
I NOTICED THAT THEY LEFT THE CENTER SEAL OFF THE FUEL FILTER WHEN FITTING BY MISTAKE
We didn't Graham. That's just the edit. Thanks for letting us know, though. By the way do you know you have caps lock on? 👍👍👍
@@HermanHitstheRoad He is shouting at you.
God I hate my 2000 1.9td Fiat Ducato, worst vehicle I've ever owned. The gearbox is made of parmezan cheese and has cost me thousands in repairs over the years, beware of water ingress, steel baulk rings die very quickly. The scuttle has a couple of design issues leading to gearbox being watered regularly. Just about to weld up the drivers sill and inner sill/footwell then it's adios amigo!
That doesn't sound good, Joe. I hope it all works out for you in the end. Will you be replacing it?
Is one guy the owner and the other the mechanic? One does it all and the other barely hands up a spanner. Is he being paid? Most of us are stuck on our own doing it all and muddling through - we don't have a talented mechanic on hand.
Hi Tony, Chas and I are friends. I own Herman with Zoe. Chas is a retired mechanic. Of course I help but I'm also holding the camera and making the RUclips videos. Obviously, there's a lot I edit out too.
I hope that answers your questions. Stay safe 👍👍😁
Replacing the fuel filter to cure black smoke is a waste of money!
The reason the engine admits black smoke is a lack of air into the engine!
Or faulty injectors!
It could also be caused by collapsing or week air induction hoses!
Moving on to the fuel filter, the filter that has the white bung with a hose attachment is for periodically draining water that sometimes accumulates in the filter!
The black bung with electrical wires attached are wired up to your dash that tells you, you have water in your fuel filter!
CHANGING YOUR FUEL FILTER WILL NOT CURE BLACK SMOKE!
It did stop the black smoke though, Mike. Thanks for commenting. I hope you enjoyed the video?
@@HermanHitstheRoad the fuel filter change did not stop the black smoke my friend!
Take it from me I am a fully skilled diesel mechanic!
The only way you get black smoke is from a lack of fresh air entering into the engine and or a egr problem! But this later egr would not show up until you were driving at a certain revs!
The only other cause would be your injectors over fueling!
The replacement of your fuel filter, although it's good to change at the correct intervals WOULD NOT CURE YOUR BLACK SMOKE PROBLEM!
you cured it by changing your air filter!
Thanks 👍👍
