As the title states, is the reamer really necessary?


How much soot has come out in your experience?

Has anyone cleaned the holes but NOT replace the glow plugs after? Did u notice any improvement?


I just really don't feel like spending $35 on a reamer... Not to mention shipping and SALE TAX (I live in the same state as Kent's company so I have to pay sale tax) which makes this 50 dollar tool....

Sooooo do I really need it?

If so,what size reamer is it? (Kent won't give out that info for less than $5.95)

And lastly, if I do can I just buy a reamer from the hardware store and use a pair of vise grips to hold it rather than the wrench method?


My car is a 1980 300d non turbo with around 230k miles and as far as I can tell all maintenance was done and on time at the dealership up until 120k, so maybe they have been cleaned before. I'm sure maintenance was done after that but that's just when the oil change booklet ended, this was a one owner car


Please help me get an answer to my question before the MBZ Source rant ensues. Thank you.
