There is no knocking of any kind at an idle or when in drive. I drove the van about 10 miles before buying it and then about 25 miles home. The van has been well maintained all around and the actual owner is in NY and I bought it from his father who didn't drive the van, so he didn't even know the gauge was not working (son is not available to ask due to out of country).
I thank you again for the quick reply and will look into making a donation soon. I'm a female and have no car savvy guys friends to ask questions too so this forum is a god send. Lol.
