Hi Guy, Good one here
Have a'03 impala 3800NA and was working on removing timing cover due to coolant leak. I removed the Harmonic Balancer Bolt but when trying to put my pulley puller on it I couldn't hit the internal threads when putting the bolts in the access holes. I looked in through the access cover holes an can see the internal threaded pulley holes threads are shifted over just out of range of the outer access cover holes. The red cirles in the pic below show where the internal threads are.
I did a complete UIM/LIM gasket and l26 aluminium UIM conversion job last summer and didn't have this problem when removing the HB.
How can I realign this???? I tried putting the crank bolt back in and turning the crank but that of course turns the cover so no help. I dont see anyway to turn the access cover by its self to align the access holes to the internal threads.
I thought this is one solid piece as I remember so how can this happen? Any advice?
