if I get it rebuilt should I get the injectors cleaned also?

They should flow match them with the pump by bench testing and measuring the output from each injector. I think someone put a video on the previous page. Dont take it to a mechanic, take it to a fully fledged injection workshop.

Injectors usually suffer form one or 2 problems. The nozzles wear out and cause diesel to dribble or the spring inside the injector gets tired and opens the injector too early.

thanks ozcruiser and thanks again rosco. I watched the video that was sent to me. looked pretty technical. imagine that's necessary if its done right. I have been adding this diesel treatment called kleen I think and have started using the lucas brand also. I kind of think lucas may be pretty good. think that may keep this 'modern' diesel from eating up the O-rings?

When or if they replace the o rings, it will be done with new type, I think its Viton. They came into common usage in 97 and is resistant to the new types of diesel.
 
for my 2lt IP I sourced the seal kit from an online shop (think roughtrax -uk)and manufacturer was not Denso, but Bosch. The Toyota garage where I took the car was happy with those seals. 1.5 years later theres no problem with the IP pump.

It would be my guess that a fuel leak that stops after warm up from the IP area means bad seals in the IP itself.

My TDI jetta is doing the exact same thing. When it's below freezing, it leaks. Above that and all summer not a single leak on the injection pump.

However, I think everyone is right and that you should probably just send it off to have it bench tested and seals replaced. My injection pump sat for almost 4 years and things are/were gummed up and stuck. My pump looked pretty clean and nothing at all like the one @roscoFJ73 posted up. I had plans to just stick it on and run, but after being told the injectors were all gummed up (but able to be cleaned) it made $ense to check the pump. This was an unexpected expense for sure, but it's not going to run right or possibly at all how it was.

If you fix it, you probably won't have to deal with it again in your ownership.
 
thanks for the advice guys. I talked to Rob at Odd Iron and if it comes down to where I have to I will send it to him for sure. he seemed very helpful and very honest. he mentioned a couple of diesel additives. one was Stanadyne and one was XVP. he said the pumps he got where people were using these, their pumps looked a lot cleaner. I was using Kleen and a Lucas product but I think I may try the XZP stuff.

That whole "diesel thing" is kinda Odd Irons speciality. :)
Thanks for the kind words.
