<< < (2/2)

davidlandy:
they genuine bosch ones - done about 20k , no veg oil.

Range Rover Blues:
Does veg oil damage them then :-k

Disco_Stu:
Im not sure to be honest. Mine have had loads thru them and it didn't worry me at the time but if i'm paying for them, I'd like to know they're spot on.

L90OOK:
I think veg oil eventually degrades seal as there is no lubrication.  I run my landies on veg oil with no probs...yet!  :doh:

DiscoDan:
Hi.

Not sure on the interval for injectors but if your only fault is the puff of smoke at startup I wouldn't worry as they all do it! They also all have a slight lack of power when you are thinking about it!

As mentioned above, new injectors are unlikely to produce a noticable difference without other work also. You could have the pump removed and reconditioned. If you find a Bosch service agent they will do the injectors too, a proper recon will leave them as new.

Otherwise, regular servicing of the filter & sedimentor will always help. There is also the common problem of the corrosion to the metal pipes on the fuel sender, pin [ed - prod with a sharp implement] holes here could give you air in the fuel which might give you a lack of powerbut they usually cause other problems at the same time.

HTH, Dan
