Potterton oil boiler won't start

Called engineer who said it was a tank problem, he fitted a temporary pipe which is coming out of the top of the tank now not at the bottom. The pipe has a little round device before it goes through the wall to the boiler,this has a button on it. There is no oil coming through near the boiler when I tried to bleed it, I have also undone the small nut on the left hand side of the boiler to let any air out (engineers instructions over phone). There is oil coming out of the pipe OK before the small device mentioned earlier, but not a lot when it is put back on, is this right or is this the problem why the boiler won't start. Engineer can't get to us for a few days and l am reluctant to get him back it's costing me too much money, this is the third time he's been! Hoping someone can help me. many thanks.

SOURCE: brakes

Did you have this problem before you replaced the M/C? Inspect your brake system for leaks, especially the rubber hoses. Make sure all fittings are tight. Sometimes the caliper's seal around the piston will allow air to **** in, but won't leak fluid. Many cars from the 80's onward had pistons made out of plastic which causes a sticking and leaking problem. Many times rebuilt, loaded with pads, calipers cost just a little more than what a reseal kit costs. They have to be cutting corners somewhere.

If your vehicle has ABS, sometimes you have to hook a scanner up to bleed the brakes correctly. If you don't have ABS, you probably have a proportioning valve and these can cause trouble, especially on a high mileage vehicle.

SOURCE: 1995 BMW 318Tds Fuel Starvation Problem

Sorry this is not a solution. Just to say I own a 1997 318tds which only starts on the button if the tank is at least half full. This was looked at professionally shortly after i bought the car 3 years ago.( I did wonder why it was sold to me with such a full tank). I was told it would need the fuel tank replacing. Bearing in mind the value of the car & the fact the owner is now too geriatric to do major repairs, I just make sure it is always half-full, and live with it.. This could be your problem. BMWs chap said it was logged on their system as a known but unusual fault.

SOURCE: Water leak from top of expansion tank.2000 BMW 316i se

The water (coolant) in the expansion tank will rise and fall with the engine temperature. What the expansion tank does is collect and return coolant to and from the engine. When the engine warms up the coolant gets hot, builds up pressure and opens up the radiator cap. The coolant then goes into the expansion tank. Now when the engine cools down the pressure drops in the cooling system and the pressure drop (vacuum) pulls the coolant back into the engine via the radiator cap. The radiator cap allows the cooling system to build up pressure and by doing so increases the boiling point of the coolant, but when that pressure exceeds the caps rating the cap opens and the coolant goes to the expansion valve. The cap has another part to it that when the engine cools down and a partial vacuum is created in the cooling system a "valve" in the radiator cap opens and allows the coolant to be drawn back into the engine. I would look at your radiator cap to see if any gunk or build up is on it, and check the rubber gaskets for cracks. It's easiest just to replace the cap because they are inexpensive and easy to replace (2-10 dollars). The expansion tank should have two hoses on it. The one on the bottom comes from the radiator and the one on the top (possibly part of filler cap) runs down and is open to the ground. That way if it is overfilled or becomes overfilled it will slowly leak onto the ground. When and if you change your radiator cap, make sure the engine is cooled down, remove cap and start engine and turn heater to full blast, full heat. Leave the cap off and let it run until engine warmed up. This should burp out any air pockets that may have happened when coolant was changed. Also top off the coolant in the radiator while it is running. Hope this helps and good luck

I put diesel in my F-150 unleaded gas tank and now it won't start.what do I do


I hope you've flushed the fuel tank after the mistake. There could still be diesel in the system, and diesel does not evaporate like gasoline. Diesel will, however, burn off if the engine is hot enough, so you need to get your engine started.
1 Fill your tank with the proper grade gasoline.
2 Try to get the gasoline through the system as far as possible - loosen the feed pipe as close to the carburettor or injector system as possible, switch on the ignition to get the fuel pump to displace any diesel in the pipe (remember to place the end of the pipe into a container so you don't spill the stuff on the floor). Otherwise just suck at the end of the pipe (not recommended) until the gas comes through.
3 Reattach the fuel pipe, then prime the engine with ethanol - also called Quick Start or similar.
Spray the Quick Start into the air intake while cranking the engine. It should start, even for just a few seconds. Repeat this a few times until the engine starts then let it run until the smoke from the exhaust stops. It is not the end of the world to have diesel in a gas tank, much, much worse is getting gasoline in a diesel tank!
This is a first aid remedy, hope it helps.

Smoke from a side pipe


Leaking exhaust pipes and deflated radiator can be the result of this. Better start with the radiator first and check if its deflated. Also make sure the pipes are tightly mounted and double check any leak.

How to replace fuel pump on a dodge ram


In order to replace the fuel pump on a dodge ram follow the instructions below

The fuel pump on this vehicle is electric so check all fuses and relays to ensure this isnt whats causing you the problem as it is quite a big job to change the fuel pump.

1. Make sure you purchase the correct fuel pump as their are different size and shapes depending on ago of vehicle, model of vehicle and engine size the type of pump will vary so make sure you buy correct type.

2. you now need to relieve the fuel system of pressure you can do this by removing the pipe that goes to the injectors put a bit of rag over it to stop it spraying any where, their wont be loads come out its just pressurized.
Also undo the negative lead from the battery.

3. you now need to drain and disconnect the fuel tank ie undo the pipes coming from the tank be careful of the filler hose this will also need undoing.
Remove the fuel pumps electrical connector and remove the fuel lines connected to the tank.
You should now be able to remove the tank

4. You can now get to the fuel pump, you need to remove the lock nut holding the fuel pump in place turning the nut anti clockwise.
Discard the o-ring between the pump and the tank.

5. Now your ready to fit the new pump, fit the pump using everything in the kit and make sure you use the new o-ring.
You must make sure that the allignment tab that sits under the fuel pump fits correctly into the notch cut into the tank.

6. Tighten the locking nut to 40in lbs.

The refit everything in reverse order. When your ready to start the engine it may take a few turns for the air to come out of the system, if needed you could leave the fuel pipe off the injectors and switch the ignition on making sure the pipe is in a bottle so you done get fuel every where, once you have fuel coming out refit the injector pipe and now you should have no problems starting the engine.

You are doing this work at your own risk, its not the easiest of jobs to do and is time consuming on a scale of 1 to 10 with 10 being the hardest i would say the job is about 3.

If you are unsure what you are doing or dont have the correct tools then leave it to an expert.

PLEASE MAKE SURE YOU RE-FIT THE INJECTOR PIPE IF YOU DID UNDO IT AS YOU COULD CAUSE A FIRE IF THIS PIPE IS LEFT OFF AS YOU WOULD HAVE FUEL COMING OUT OF THIS PIPE AND IF YOUR ENGINE SPARKS OR SHORTS YOU COULD SET FIRE TO YOUR VEHICLE.


Make sure the tank is empty as it can be really heavy if the tanks has fuel in.

Leaking fuel pump


If the fuel is leaking into the car you will need the replace the seal on the top on the pump assembly not the seals on the pump itself but before changing the seal just double check the fuel lines are tight and the leak is actually from the fuel splashing out of the tank. The seal your after is referred to as the pump assembly oring ( big rubber oring around the top of the assembly a smear of silcone can be used as a temporary fix but erge you to get it fix properly as soon as possible and fuel fumes in the cabin can be extremely deadly)
Hope this helps

Engine runs about 15 minutes then dies. acts like it is out of gas. will restart after sitting several hours.


Well iv had this problem a few times in the past so will let you try some of them ,
1/ Fuel pump in fuel tank overheating ORfuel filter not letting fuel passing ,ANSWER remove fuel pipe to engine and feed into a bottle turn on key and see how much fuel comes out without stopping, if ok go to fuel tank and check the breather pipe (make sure its clear).
2/ If engine runs well when you first start without missing and idles well,but then dies at 15minutes
when you try to start again dose it seem to turn over faster or slower?
3/When engine running check the rear tail pipe on exhaust check for smoke and put you hand over the pipe hard to stop fumes (dose engine run rough and stop?),as the muffler or converter can be blocked more so when hot.{use a glove on your hand}.
4/When the engine stops take out No1 plug lead and fit a spare plug in it and lay on top of engine and spin engine over ,does it spark?? as it could be the coil overheating which would also do it if no spark.
5/ Chech coolant sensorplug for bad fitting Also check Crank Sencer and coil wire to distributor.
Let me know the results Ron

dear friend: i think that your terracan is actually running out of fuel even if the guage shows quater,you can also put the old fuel filter back and try it,we did discover some of the new filters sucking air.

(2000 Hyundai Atos 999cc) can you please solve my car problem.


hi this may sound odd to you but worth looking into ?? from what you have described may i suggest that your problem may be the fuel tank is becoming vacuumed due to possible tank breather being either blocked or kinked ? this will allow car to start ok and run for some distance whilst the engine is using fuel drawn from the tank via fuel pump ok? then as fuel is used it is not being replaced by atmosphere air in tank ? resulting in vacuum so engine is starved of fuel as pump cannot overcome vac and fuel delivery to engine slows ? but when you stop the vac will slowly clear and all is ok till next time ? try this temporary leave tank filler cap loose an road test if no prob's then check the breather pipe normally clipped alongside filler pipe? under wheel arch ? where all rain/mud etc will come into contact? hope this helps ?

How do you change the fuel filter in my 94 prelude SRV?


There 2 filters on your car:

1. By either the left or right suspension strut tower (gold colored canister)
2. By the gas tank

I suggest you replace both.

The one by the gas tank is like a prefilter and I will start with that one first:

Jack up car and put on axle stands or ramps then locate filter on the fuel line. Disconnect hose clamp from gas tank hose side FIRST (inlet) and use a spare bolt to block off the line otherwise fuel will spill all over the place.

Disconnect other side (outlet) then replace in opposite order.

You will need to use the grip part (not the cutting part) of a pair of pliers to GENTLY twist the hoses to break the seal on the rubber hose has made on the pipes as after years of clamping pressure they are bound to be tightly sealed on there. Remember to do it gently as you run the risk of crimping the pipes (not good!)

Also the filter should come with an arrow stamped on the body of it. Be sure to install the new filter with the arrow pointing towards the front of the car (this is very important as they are designed to flow only one way)

Sometimes these filters dont attach with hose clamps. In this case you will need a flare nut spanner (see below for explanation)

Now for the one in the engine bay:

It might pay to disconnect the battery to avoid the risk of fire.

I'll warn you that the fittings on this one are pretty tight so you will probably need a big bar with a socket to crack them.

The top fitting is what is known as a banjo fitting whereby a big bolt goes through a ring that is connected to the pipe.

Below this ring will be a hex (like a nut as part of the body of the filter). Attach an appropriately sized spanner on the hex then attach the bar with socket to the nut.

The spanner on the hex part is used to stop the filter from twisting while you apply pressure to the bolt to undo it (you may need someone to help hold the spanner). Only undo it untill the boolt has 'cracked' then leave it.

The other fitting (inlet) will either be on the bottom of the filter or at the top by the outlet but either way directions are the same:

You will need whats called a flare nut spanner (also called a pipe spanner) the right size for the nut fitting. It's like a ring spanner but with a cutout in it to slip over the pipe and over the nut fitting.

You also have a hex type fitting on this side too so attach appropriate sized spanner, attach the flare nut spanner and loosen as you did the other fitting (using the spanner to stop the filter twisting).

Take both pipes off but be careful with the banjo fitting side as there are copper sealing washers and you want to remember where they go (replacement washers should come with the new filter)

Replace washers and fit pipes in reverse order, attach battery, start up and enjoy :)

Hope this helps :)
