suspect crank can no longer turn the oil pump....threw a rod and won't be long before you're welding up the oil pan to put on your new short block~

The smoke is black and when I checked the oil, it was black too

Kimberly Thomas

It also stopped when I was driving. Waiting on AAA now

oh no...threw a rod...happened to my 400 impala engine installed into my 66 pickup truck...had to push it UPHILL on the 880 industrial road off ramp....thank god for parking brakes...that's all I gotta say~

that motor admittedly has 191,000....? I'd start shoppin' for a short block NEAR to the installer who's puttin' it in~....that was just a suggestion...although They aren't givin me points anymore...I appreciate the 20 point reward...'tis a wooden nickel for me~

okay...that one DOES come with a warranty, for what it's worth....who can argue with FREE SHIPPING? Returns: 60 days money back, buyer pays return shipping

but knockin' to beat the band from the heart of the motor sounds injured beyond reconciliation...okay maybe there is a problem with the intake air temp sensor....producing a rich condition...and thus the black smoke you see...but it's like havin' your beard trimmed before the beheading~

The odometer says 62000 miles on it
