Van Problem

the_chauffer

Looking for any ideas or advice please.


I recently started a new job for a local charity and we are having a huge problem with one of our removal vans.


Its a 51 plate LDV Convoy. It currently has the 2.5 TD engine out of an M reg Transit in, but they had the same problem with the old engine (think thats why they changed it).

Now for the problem. When you go up hill with it, you get a severe lack of power then it cut out and wont start up again. Ok on flats and down hill, until you take it up hill, then after that you get the same problem (if you get it going again).

I know its had some work done to it, as Ive done some of it. New pump head, new starter. I personally notice the oil was to high, I dropped over a gallon out of it to bring it down to maximum (I know, people that dont know what they are doing, shouldnt touch). Now when I put the starter the other day I did have to open an injector to bleed it up, as it wouldnt start.

The AA seem think its an electrical fault (been towed in a couple of times). Now me and few of the other guys think its going to be a fuel problem, but we just cant seem to find anything.

Whats getting us its a new engine to the van and its the same problem.

Any advice, knowledge or ideas welcome. Any more info need just ask me and I will try to help.

Thanks in advance for anything.

Crud in the fuel tank, or a duff lift pump?

If it was overfilled by a gallon, there could be a whole raft of things wrong with it such as bent conrods and valves but we'll assume not...

As epninety said, there could be crud in the tank or possibly the pickup pipe strainer. When you take off the fuel filler cap do you have to pull at it to remove it (like there's suction holding it in place) or does it come away easy ? Has the fuel filter been changed or the water drained off?

The filler cap comes away with no suction holding it. I have drained the tank and found nothing in it, but not sure on that, may not have completely drained it.

I know the damage that can be caused by over filling, but like I said the main proble they are having was the same as with the old engine.

You really need a good diesel mechanic to have a look. It sounds like the old engine was junked in haste when it could more readily be signs of an air leak in the fuel system. (Unfortunately anywhere from the tank to the injectors). If its the transit engine with the little pushrods (which bend, but can easily be straightened) a lot of people scrap because they think they have wrecked the engine.

a 16 year old transit engine was never going to be spritly was it?

is the turbo working? do you have any fuel leaks?

also as someone else said if its had a gallon too much oil in it this could have caused some damage.

i often see these ldv's struggling up hills on motorways at 40 and 50 mph being overtaken by artics. they never were much good.

have you tried brimming the tank then trying it uphill
dont see any reason why the engine would need to be replaced for this issue

personally i would be dropping the fuel tank out and inspecting the pick up

Been having a google as well. A lot of people haveing the same proble say it may be the EGR valve. Gona have a look at that, then the tank and lines. Other than that looks like it may be the injection pump or injectors.

What do you guys think?
