Hey there!

Iam refreshing an old 2003 doblo cargo and i have hard time findind infos about this car. The preheat glowplugs are completely done , could anyone confirm to me that i have to remove the motor support, in order to remove the intake? It's a hell of a job, i worked on several indirect injection diesel before that, and I did not expect that removing the head cover would take me so much time.....

Otherwise,if any one could tell what is to be watched on this 1.9D, it would be super useful info. There is an oil leak i did not enquire fully about , but if anyone could tell me what is probable...

thanks!

Is that the horrible 1868cc? possible used in some Citroen and Peugeots of that era?
As opposed to the 1910cc Fiat engine which was faster and more economical.
 
Yes that's him ....!
This uTube video may be of interest.
Basically I had an 03 Fiat Doblo Cargo with the 1868cc (Peugeot DW8 engine) it was fitted with the Lucas Epic injector pump and was total crap, gutless and uneconomical.
I bought it as a non runner after a diagnostic company and another garage gave up on it so I paid £300. I managed to get it going after tracing the fault to an air leak on the fuel line at the tank. Basically they have no lift pump and rely on the Lucas Epic to "suck" the fuel all the way from the back of vehicle. I traced the fault by getting it going from a gravity supply on the wing of van.
I had and have several Doblos 1.3 and 1.6 MJs, I can honestly say I would never buy another 1868cc (DW8) version.:(

I am not so sure now, could you tell me which one is it ?
What I find absolutely crazy is the access of the GP, it is so.narrow, completely stuck to the IP, and the support motor. This is plain stupid.
Yeah, I ve heard about how weak Lucas pump are. I am very happy with my VE pump on my Volvo 240. The car is sluggish, but the diesel system is very reliable, and easy to work on.

Looks like the Lucas pump, I agree about the Bosch VE pumps, it looks like at least one heater plug is blocked by the injector pump:(
The fuel filter looks familiar and no sign of a primer, I assume no electric pump in fuel tank?
 
Yes , no primer, no electric pump .....
I will also have to change injectors ring, it's leaking a lot.
I hope I'll be able to prime the system again ....

It may be worth fitting a manual "squeezy" primer outboard motor type that some Peugeot's used in the past.
I think you can buy them from car accessory shops.
If it is leaking diesel from the injectors it may just want the different sections of the injector tightening a bit.
What was the original issue with the vehicle, I assumed it ran alright normally but was hard to start on heater plugs from cold.
With that poor Lucas Epic injector pump system relying on sucking the fuel all the way from the tank it encourages air to get in which stops diesels from running very quickly.
