Hi everyone-
Great board! I've been reading you-all for over a year and finally had to take the plunge.
I've searched this thread and have not been able to find any info on my problem, so I was hoping someone could help.
I own an '01 Duramax/Diesel Ext. Cab and last fall started getting a tapping - maybe loud enough to be called a knocking - when towing loads under stress (up hill/passing). My trailer probably weighs about 10,000 - 13,000 lbs.
This noise keeps time with the RPM and starts out an annoyance, but can get quite loud on the big hills. Seems to sound metalic in nature and seems to be coming from just in front of dash, in center, down low. This truck not make this noise for the first 14,000 miles of it's life. Milage is now around 30,000.
Took my dealer's diesel mechanic for a ride with trailer in tow and was able to reproduce the noise. He called GM and says GM knows of 2 problems - one tapping (described in detail elsewhere on this thread) and then also the knocking problem. GM is autopsying engines with these problems to try and figure out what's going on. Meanwhile, they say to keep driving it.
I am getting ready to leave on a solo trip from mid-Atlantic to Oklahoma with horse and trailer in tow. I really would like some opinions on whether this noise could turn into my rig going kerpluey in the middle of nowhere.
Does anyone have experience with a problem like this one? Any advice on what to do next? :confused:
Thanks for any help!
