Record by record

1 records state a cause or a remedy. Each record is shown as short labels in the order fault → finding the cause → correction. Press a label to narrow to the records that state it.

Symptom

Component named as the cause

Work done

How it is said to have ended

  • says it came back2

A ribbon is as wide as the records that state both of its ends (only the commonest are drawn). A record that names several symptoms or components runs through each. Orange is records that say the fault came back or was not fixed. Results come from owners’ reports only; one that does not say is “result not stated”. None of this is a likelihood of a cause or a rate at which work succeeds.

    Fault
    MY CAR BEGAN TO HAVE A BUILD UP OF SLUGS AND BEGAN LOOSING OIL PRESSURE AND COOLANT AND NEEDED OIL ADDED AND COOLANT FREQUENTLY.
    Cause
    I WAS ADVISED TO CHANGE THE OIL FREQUENTLY TO CLEAN THE SLUG OUT BUT IT CONTINUED TO BUILD UP AND THE MYSTERY OF LOOSING COOLANT OIL PRESSURE HAS BOTTOMED OUT TWO MORE TIMES AND I FOUND A ARTICLE ON THE INTERNET THAT A NUMBER OF GMC VEHICLES INCLUDING MINE WERE BUILT WITH DEFECTIVE CYLINDER HEADS DUE TO CRACKS OVER TIME WHICH ALLOWS COOLANT TO LEAK INTO ENGINE AND MIX WITH THE OIL WHICH BUILDS UP SLUG.
    Remedy
    THE SLUGS WERE CLEANED AND A NEW OIL PUMP WAS PLACED BECAUSE OF THE BUILD UP OF SLUGS.
