The Joys of Rod Knock

April 28, 2009 – 6:49 am

The legacy is spread all over my garage again.

We noticed that the car was running lean under boost, and although I didn’t get any misfire codes or hear any detonation, I suspect that a rod bearing is on the way out. After replacing the fuel pump we fired the car up again and noticed a tapping/knocking sound emanating from the engine between 2000 and 2500 rpm.

So it’s time for a complete teardown, hopefully it’s just a bearing and no other damage has been done. Right now I have the engine out and on the stand, and I’m waiting for a hardened 10mm allen socket to break the notoriously-difficult cam gear bolts loose.
