Re: [MBZ] 240D Knocking
There are two ways to used Diesel Purge - pooring a can or two into the fuel tank, or disconnecting the fuel lines under the hood, and running the engine solely on the Diesel Purge. The later method (recommended) will not do anything to the filters. The first method could clean stuff out of the tank that could clog the filters. The second method (fully explained on the can) will do the most good in the least amount of time.

Re: [MBZ] 240D Knocking
Raving about Diesel Purge aside, there is a whole series of other things that can cause this. It is commonly described as nailing. Two of the most common causes, aside from crud buildup are a bad injection nozzle or a broken prechamber. There is a little ball supprted on a pin inside the prechamber. sometimes the pin will break.

Okay, disturbing - my nice engine might not be doing so well. Hmm.

Re: [MBZ] 240D Knocking
John, I have the same car and have been hearing the very same noises you describe upon cold startup. Normally I am alarmed by anything unusual with my automobiles, but I have heard it said that these engines percolate and crack and pop when started cold. BUT: Bear in mind that I don't know what I'm talking about - so am I wrong, list, for not being alarmed? - should I be worried by that pinging noise? I see LT Don says diesel purge is the answer, though he says autumn follows winter. ;) Also, when running a diesel purge treatment, should one be equipped with some fuel filters for when the gunk gets moved up the lines? And if gunk plugs up the filters, will the engine quit cold and not start, or will there be a warning period of poor running? How does the slogan go? I have questions, you have answers?

Re: [MBZ] 240D Knocking
To add: that first Diesel Purge treatment is a real experience. Before your very ears, the car goes from sounding like an out-of-balance washer in spin cycle to sounding like a Singer sewing machine.

Re: [MBZ] 240D Knocking
I just changed the fuel filters in both cars. Should I wait a few K miles until it's time to replace them, or go ahead with the Diesel Purge now and replace the filters later? 1985 300CD 1983 300TD On 4/10/07, Bob Rentfro [EMAIL PROTECTED] wrote: That stuff is nectar of the diesel gods You will not believe the difference, John.
