Smoke & Injectors

(1/6) > >>

bigfatsi:
I have been struggling to sort out the smoke on my 1989 90 2.5td (see here)

I've replaced the turbo-manifold pipe and installed new air and fuel filters. I've put through two tanks of diesel with injector cleaner yet it's still smoking  :cry:

When I went greenlaning at the weekend we covered around 220 miles and when I looked under the bonnet there was a lot of oil (or looked like oil) around one injector in particular (There is a pic in my gallery although this was taken before this weekends outing.) Could this be the cause of all the soot? My train of thought is this: Injector put back in without steel or copper washer(s) and is not fully sealing. This makes the injector sit further down in the chamber affecting spray pattern. So between the poor pattern and the lower compression this would, I assume, make this one cylinder burn poorly (but still some compression to burn a bit - hence no 'misfire') causing noise, vibration, poor fuel economy, leaky injector and lots of silky black smoke? It seems plausible to me however I'm not sure if the injector sprays into the cylinder itself or into the manifold or chamber in manifold? In which case I'm probably talking a load of cr*p!

Does this sound like a possibility or the ramblings of a guy desperate to hold onto the hope of not spending wads of cash!

I have ordered the washers in case, but is it worth changing the injectors too? I've found a set of refurbs for £88.50.  :?

Speedy reply appreciated as I would like to get it sorted before this weekend!

Cheers!

Simon.

Rather than chuck money at injector cleaner and new injectors, start saving for an early rotten disco with a good 200tdi engine in it. You will probably get one for about £500.
 
Buy an exhaust downpipe from Steve Parkers for about £120.

stick those bits into yours and you will be grinning from ear to ear with the difference its made.

Well worth it.  :wink:

bigfatsi:
If only I had £500 to do it with!  :cry:

I will hopefully get a 200 or 300 at a later date when I can find one at the right price and then set to rebuilding it in the garage and getting it sweet as a nut. However in the meantime there's a whole lotta mud out there I wanna get in quickly and cheaply!  :D  Do you think the injectors would do this?

Simon.

davidlandy:
the danger is if you start buying loads of bits that arent needed then you will soon get to within a shouting distance £500 wihtout too much trouble - its a landrover remember!

I dont think changing the injectors will do the trick - gut feel, seen so many people spend money unecessarily in this area. The TD engine is a fragile piece of kit and there arent many good ones out there. If the smoke isnt that bad then you may have to live with it.

ps got a complete TD engine if you want it cheap?  that too smokes but runs ok!

Hmmm. Bits. How much?!
