Hi Folks,
bought an 84 K2500 6.2 J-code, manual tran. Truck runs great, starts good cold and hot, good mileage, etc. I was told that the 92000 miles on the odo was actual, was owned by little old man, was never worked hard, etc.
So, I checked the oil about 2000 miles since my last oil change and it was a quart low. After reading around here it seems valve seals aren't likely to be a problem, so I did the blow-by test. Warm, with the oil cap off there is a steady series of "puffs" coming out of the tube. It isn't a constant stream, but does continually puff in pulse with the idle. :confused:
Is this normal for a low mile 6.2 or do you think the odo was rolled over? In any event, how bad is "bad?"
Thanks for any help you can offer....
