Nissan Patrol Y61 ZD30 3 Litre Common Rail Diesel Fuel Injection problem cheap repair fix 

Well done on sourcing the problem

The brother to the Nissan is the Ford Ranger /Mazda BT50 uses same design by Bosch . These vehicles have the same issues .

What are the risks of removing the banjo bolt and replacing it with a solid bolt? How did you know that the new relief valve wasn’t sealing correctly? It’s seems like a pretty straight forward fit with a simple o ring seal. I have been known to be wrong before though. Thanks

Pressure relief valve is there for a reason. You can now crack the rail or worse start making oil because you will have over pressurised injectors which could start leaking off. Symtoms of over pressurised injectors over the long term is holes burned through the pistons, or big end failure due to oil dilution. Unfortunately the only fix is to replace the rail.

Would you be able to tell me what size bolt it was? Thread pitch and length would be great, thanks

What size is that bolt? I'm planning to take one with me as a spare.

Have you had any problems since doing the mod cause im having same issues

Gud day sir..my patrol zd30 di get hard strting,i also obsrve that the engine oil increase and my diesel frm fuel tnk gets dark color.wat d u thnk s d prblem?

With the banjo bolt out…..did you get any diesel coming out of the banjo/line when priming? I’m not getting diesel coming out of the PRV at cranking but some is coming out of the banjo/line.

Good day sir. Valuable information. Can you please give me the part nb for the banjo bolt?

Thanks mate.. M y 2011 Nissan Patrol Ti had trouble starting when cold.. I took that pressure relief bolt out and replaced it with a sollard one and the car starts great now.. :)

Hay mate great vid. I think I’ve got the same problem. My Patrol won’t start without pumping the hand prime. And sometimes won’t at all. I replaced my pressure relief valve and I feel it’s running better more power using less fuel. I’m guessing the banjo is leaking.

Have any issues with this fix mate ?

I have a Nissan patrol ZD30 engine, it can't start when in neutral (auto) but it starts when in "park". When you drive for about 30mins to 1 hour and you stop when still in "DRIVE" too much black smoke, rough idling. What would be the fault?

hows this going to this day?

My ZD30 CRD stopped while heading back from Cape York. Mechanics in Cooktown changed the Fuel pressure regulator and it ran like a dream. They also said its a common problem with the CRD's.

how is it going
