Car Forum / Peugeot Cars / April 2005405 diesal leak
i got a 405 turbo diesal 1.9 with lucas fuel pump and got a serious diesal leak from the engine compartment near top of engine i think. it appears to be from cam belt side of engine rather than from fuel pump section on top i checked all pipes going to pump and nothing from there has anyone got any ideas? when i say serious i lost bout 1/2 tank of fuel in couple of miles. it only leaks when engine is running not when ignition is on if that helps Hi, I'd bet that Diesel pump's drive-end seal is worn. Have a Diesel specialist to replace the seal. It happended on my brother's '91 205 TD. Come on, it's a Roto / Lucas pump ?

But I have known it on the Bosch type too, though only once or twice. Lucas much more!!! >>Hi, >> [quoted text clipped - 11 lines] > I agree.

Lucas much more!!! usually doesnt make a difference on the make it usually down to overtightening of cam belt or the occasional fill with petrol by accident Hi, > usually doesnt make a difference on the make It seems it's much more common with Roto's. Damn', my car has a DPC ! > it usually down to overtightening of cam belt or the occasional fill with > petrol by accident Possibly. Third choice, wrong type of fuel return "valve" (don't know the real term), happened with my brother's car : Bosch valve fit to a Roto pump. As Bosch's have a lower return pressure, the hole is a bit less big - this causes an overpressure which cracks the seal. That was the diagnostics of the Diesel specialist which overhauled the pump. Having later compared with my return valve, yes it's far bigger on Rotos.

Giving the pump to a Diesel specialist would be my best advice anyway, as opening such pumps really requires that you know what you're doing - and I wouldn't consider taking the risk ! Excepted for easy ops like throttle actuator cover change, of course.

Doesn't cost that much to get the seal replaced as long as there is no other damage. Of course you would have to get the pump off, but you would have to do that whichever route you took. > >the engine was acting very sluggih hardly any power then the power came > >back but with the leak does that work with the theory about drive end seal?

Just make sure that the leak off pipes on the injectors are still OK. I had a similar problem with a leak, top offside of the engine, and it was the leak off pipe on the timing end injector, the one which is just a plug. Worth checking before stripping half the engine down. Brian. if it leaks only when running, its worth checking the fuel return pipe, as this could be the problem, and it is in the timing belt area, Fitzy >> >the engine was acting very sluggih hardly any power then the power came >> >back but with the leak does that work with the theory about drive end [quoted text clipped - 12 lines] > > Brian. > if it leaks only when running, its worth checking the fuel return pipe, > as this could be the problem, and it is in the timing belt area, [quoted text clipped - 17 lines] >> >> Brian. also bear in mind that if the belt is contaminated it needs renewing too i tried looking for the fuel return pipe but cant seem to locate it in the timing belt area there doesnt seem to be any pipes around that area at all i think the fuel return goes round other side doesnt it ???? |
