Hi guys


This is a general question, though possibly Jerry the Guru might answer it as it is concerning the C223:

As the Bosch VE (or any IP) wears, what symptoms typically become evident? What are the signs of pump wear?

My IP has been tampered with before I bought it, as the other 2 engine's pumps have been also.
With this one, I turned it up to smoke a bit during heavy acceleration, as it didn't before. However, the idle can't be turned down to anywhere near where it should be. On my first engine, and the 3 VW diesels I had before it, I could turn the pump up quite a bit and setting the idle wasn't an issue (now that I think about it, all of these were played with before I got them too! <img src="/forums/images/graemlins/rolleyes.gif" alt="" /> )
With 550,000 kms on it, I'm sure the pump is getting tired, however, this problem led me to ask the above question.
I have been driving it like this for 3 years now, and it's fine. I have the idle at almost 1000rpm, which it runs smoother like that anyway, and there is more amps available at the alternator for fan, wipers, ect during winter.
Rebuilding the pump is not financially an option at this point. I may take the one off the first engine and use it.

Anyone care to throw their thoughts at this one?

GENERALLY ON THE VE PUMP WHEN THEY START TO WEAR , THEY ARE HARD TO START THE ENG , LOW ON POWER , THE FAST IDEL SOUNDS LIKE THE GOVERNOR INSIDE,WHICH IS CENTRIFUGAL, MAY BE STICKING AND WITH THAT MANY MILES MAY HAVE A GROOVE WORN IN THE SLEEVE THAT LETS THE GOV RETRACT TO PULL THE IDEL BACK DOWN , ODDLY ENOUGH THOSE PUMP CAN BE REBUILT AND WILL WORK LIKE NEW IF SOMEONE WHO KNOWS WHAT THEY ARE DOING DOES THE REBUILD AND RECALIBRATES IT CORRECTLY AROUND HERE IT GENERALLY RUNS AROUND 400 OR SO JERRY

Thanks for the response. I don't get online as much as I used to, so....
A rough guestimate on the hours is around 10,000 (550,000 kms), good chance as any the pump is worn. I was going to change it for the one out of my first engine, as it didn't have this problem. I am also going to change the timing belt, because I have no idea when, or if, it was ever changed. It will be a good time to replace the worn power steering/vacuum pump belt, and throw in a new block heater.
I'll look back in the forums and find the timing settings you once suggested. I recall it was advanced a bit more than stock. I already removed the spring and shims from the pump.

I wonder how many belt cover bolts are going to break...? <img src="/forums/images/graemlins/scared.gif" alt="" />
