Cam timing/Durametric readings/erros
Still trying to figure out if there is really anything wrong with the setting/timing of my cams after fixing my intermix problems. When I first checked the cam timing with my Durametric it was showing the following readings:
Camshaft position 1 deviation -10.86
Camshaft position 2 deviation -02.14
So I have been assuming that the bank 1 cam might be pretty far off. I ran the Durametric on my buddies car and the readings for these are about -1 to -2.
I borrowed a cam position tool from another member and went to check/reset the cam timing today. But visually, there is no way it appears to be off by -10 degrees.
Based on this I did not reset the cam timing but decided to run the Durametric again and now get the following readings:
Camshaft position 1 deviation -12.15
Camshaft position 2 deviation -02.45
Actual angle for camshaft bank 1 .1 (at idle) 25.94 (at 2,000 RPM)
Actual angle for camshaft bank 2 .3 (at idle) 24.74 (at 2,000 RPM)
The actual angles vary a little bit with the engine running, but you can see the advance kick in between 1,500-2,000 RPM.
So here is my question. Do the camshaft position deviation numbers mean that the bank 1 camshaft is starting at -12.15, and then advancing 25 degrees so that it is at 13 degrees advance? Not really sure how to interpret these readings. But it sure dons not look like the bank 1 cam is off by 12+ degrees with the engine off.
Any help would be appreciated.
