Hi all
So I bought a few months ago a second hand D40 2.5L 2007 Spanish. It has 222'000 km on the clock. I am the third owner. There are many reasons I bought this one, but the main relevant here is that I wanted to learn about 4wd cars. When I bought it, I could not tell the difference between diesel and petrol engines. BUT after I bought it, I started working weekends at mates garage, he is a car mech, and since than have learned heaps.
So far done on the Navara:
- new OEM injectors
- new OEM Fuel Filter
- new oils (engine, transmission, diffs, etc.)
- new battery
Currently experiencing issues with:
- Sometimes stalling under 1000RPM
- Used to go in limp mode but it hasn't happened in a while
Either way, at one stage it was stalling rather badly so I took it to this other mech who works at Nissan Dealership. He hooked it up to the computer and diagnosed following:
Suction control valve is playing up. He put the fuel pump in learn mode to combat this. But it didn't help much as it still happens occasionally.
Apart from that, the computer didn't show anything. He reckons the car drives fine for a D40. The only thing he suggested I do is to check the timing chain and replace it and other parts around it. He quoted me max 2400 AUD. (by max I mean all parts need to be changed...also single row chain, not double row)
I am planning to do also:
- replace the suction control valve to fix the stalling under 1000rpm as it still happens sometimes
- install oil catch can
- block off EGR or at least try to
Now the question for you guys, should I really check the timing chain? I am quite aware of the potential damage that it can do to the car if it breaks or tension loosens. Also I don't have any evidence that the first owner did it, second one didn't do it for sure.
I can't here any noise, but the Nissan mech reckons I should do it as he can here it a bit.
What do you guys think?
