Camshaft Position Deviation

[carrera3.2]

I have used the search function on this forum for this topic, but still do not feel comfortable that I have a good answer to my question.

The car is a MY 2003 Carrera with ca. 40K miles and LNE ceramic IMS bearing replacement. The engine is running fine with no error codes. To the best of my knowledge, the engine has never been opened and does not show either metal or plastic debris when the oil/filter is changed. When I check out various parameters using the Durametric tool, I get the following values for the camshaft position deviations:

bank 1 = 1.69 deg Crk

bank 2 = 5.08 deg Crk

These values do not vary with engine RPM. I believe that the factory specs allow for up to 6 degrees of deviation, but the fact that these two banks seem so different has me wondering if there may be problem waiting to pop up.

Should I be concerned about this? Any informed comments would be appreciated.

Thanks.

Remember there is a discrepancy in machining and sensors, so you are well within limits.

There is only rougly 3 degrees crank difference between the two banks, which is actually only 1.5 degrees at the cam.

Imagine what 1.5 degrees looks like on a 360 degree wheel. Not signifigant.

In other words, there is no danger of any damage, and no reason for concern.

logray,

Many thanks for your reassuring comments.

We see this type of variation all the time; you are in spec and fine.
