  2. I have been meaning to do this for ages. What I want to do is illustrate what you will find inside the engine, what's most likely to be the cause of a leak and what might also happen in rare cases. Here goes: Overall There are three areas where you may find internal diesel leaks: Behind the fuel pump door Under the rocker covers The low pressure fuel pump These pictures are of an SR2, the arrangements are much the same on the rest of the S range and in the H range too Fuel pumps: Here we have the two fuel pumps. Running across the middle of the picture is the fuel feed pipe, a copper one in this engine. Coming out of the pumps and running up inside the fuel pump housing are the delivery pipes Rocker covers: The injector is in the centre here, held down by the beam with the stud at each end. The injector pipe is coming up from the pump between the push rods. The spill rail is on the far side, comes out of the injector, loops under the beam and out the side of the engine under the rocker cover joint To try to make things clearer, this is the fuel system with the engine removed (?!) Pumps at the bottom linked by the feed pipe, injectors at the top of the injector pipes and the spill rail. There are no prizes for pointing out what is wrong with this set up Feed Pipe The feed pipe connects to the fuel pump with a banjo bolt There is a seal each side, in this case they are Dowty washers, older installations may have copper washers Common problems: Loose banjo bolts, Damaged sealing washers. Either of these will show up as leaks around the washers. As a first step, check the banjo bolt is tight Uncommon problems. Broken fuel pipe. The pumps are held down by a Y shaped clamp with a central bolt: If this bolt is loose, the pumps can move around which can cause fatigue cracking of the pipe. On engines with a lift pump, operating the priming lever may show fuel squirting out of cracked pipes Bleed point Each pump has it's own bleed point, used for bleeding air out of the pump body There's a copper sealing washer that seals the screw to the body Common problems: Loose bleed screw, damaged sealing washer. As a first step, check the bleed screw is tight Delivery valve housing On top of the pump are two hexagonal parts. The upper one is the nut on the end of the injector pipe. The lower is the hexagon that is used to tighten the deliver valve housing into the pump. The correct way to undo or tighten the injector pipe is to put a spanner onto each of these hexagons and squeeze. This doesn't always happen, and it is possible to loosen the delivery valve housing, which will cause a leak. To check this, with two spanners, slacken the nut on the injector pipe. Then tighten the delivery valve housing into the pump, finally with two spanners retighten the injector pipe A loose delivery valve housing will cause erratic running, and also leaks when the engine is not running Injector pipe Again, a loose injector pipe will give poor running as well as leaks when the engine isn't running. If the delivery valve is working OK, this is much less likely, so leaks here, at the delivery valve housing and at the injector are much less likely. You're going to notice a cylinder not working more than a leak. Having said that, three cylinder Listers do seem to run OK on two cylinders The injector pipe connections at the pump and the injector are metal to metal seals: As long as the connections are tight, they should be fine. A damaged nipple on the pipe will cause poor running Richard

  6. So you spend more money to supply good quality products, which you charge more for -- good for you. Other people don't bother and sell stuff cheaper -- good for them, it's just a different business model, low quality/price as opposed to high qaulity/price. Joe Public has to choose between cheaper and more expensive products, and very often goes for the cheap option -- and then whinges afterwards when it fails. Boo hoo, what did you expect for that price? But paying more doesn't guarantee better quality (even if it does in your case) because other vendors push out low-quality crap *and* charge more for it by ripping off the buyer -- they're not out to provide high-quality products and good service to satisfied customers, just make a fast buck. Doing "the right thing" nowadays only pays off in market areas where a good reputation and satisfied customers (who recommend you) actually pays off. But given the current reliance of most people on unverified reviews and feedback on websites -- a lot of it just plain made up -- it's getting harder to make such a business work, pile 'em high and sell 'em cheap is winning out.

  7. Quite so. Another Welsh anniversary of 50 years ago still painful in the minds of many still living although not so for any loss of life more way of living is Tryweryn. This for those unfamiliar with it was the building of a dam to fill the Tryweryn river valley (forming Llyn Celyn) near Bala in North Wales for drinking water for Liverpool. The process led to the drowning of the village and surrounding farms of Capel Celyn one of the last all Welsh Speaking villages. An example of those embittered by the experience of people with power taking what they wish (that which was not for sale) via a private members bill (no welsh MP voted for it) regardless of the wishes of those directly effected. The Capel Celyn locals marched in Liverpool as a protest and had abuse and objects thrown at them and their representatives in the Liverpool council chambers shouted down. An example of social injustice even in modern times. Still, many say that the experience has formed opinions in modern Wales and led to many political changes for the good in Wales and highlighted issues of Welsh language and culture. Cofiwch Dryweryn!

  9. Completely disagree. I've spent 12 years working with Chinese suppliers and the point with any supplier regardless of location is to work with them. We put a lot of effort into agreeing very clear specifications, agreeing processes and inspection processes and rates. My complaints rate per million units sold is much lower than many competitors. My experience has been fantastic to see my suppliers absorb information and knowledge and apply best practice's. In the locations of my suppliers they have labour laws including minimum wages and are definitely not sweat shops. I have 2 staff based in Shanghai who constantly work with our suppliers and they are superb- they work hard and are constantly learning and want to learn. It's impossible to generalise on an origin- its down to who cares enough to put the effort in and work as a partnership. Some goods from China can be excellent- some aren't, same as anywhere Oh and we don't do quality control, we do quality assurance- we ensure compliance of ingredients and processes right from the start ensuring EU compliance and our monthly right first time figures are rarely less than 100% versus spec

  10. No, on most canals you'd still see the top Peking above the water.

  11. Happened to us at Wheelock once, a chap (+ boat) joined us at the water point one evening, looking a bit nervous and asking where we were going to moor. We said maybe just round the corner. He said he had come off the last space, to take water and was going back, he'd left his wife on the bank to fend off anyone who might come along wanting to take the space. He was very pleasant about it and anyway we didn't much like the look of the mooring spot so we were happy to continue, but ultimately one cannot reserve mooring spaces even if just popping to the water point. The devil in me wanted to pull in there just to make the point, but when I saw how scary the wife was I decided against it!

  12. I am all for self defence in any situation, but some bloke with a pole waiting for a repeat cyclist coming down towpath is not self defence its assault. As for time trials on the canal thats just plain stupid, their not a race track their a shared public place. If I was knocked over on the towpath by a cyclist and it was his/her fault i would not assault them but I would probrably rip a strip off them 'Verbally'. I have crashed into another cyclist before myself, who was in the wrong = both of us clashing under a blind bridge, we both smiled and laughed. Happy Days. Lifes to short I would rather smile and get on with the day.
