Originally posted on a fueling screw thread. Wanted more attention so creating its own.
This is something noticed by my friend, who is the mechanical guru performing the head swap. But also something I’ve noticed in the past when adjusting rocker clearances.
When swapping out the camshaft sprocket (another story) and subsequent re-tensioning of the timing, Crank position was a roughly four degrees off TDC.
- Installation of timing belt procedure vs. adjustment of timing belt procedure seems to yield different results when following the manual.
Adjustment procedure specifically seems to cause the crank position to be slightly off with proper tension of belts. I’ve noticed this in the past years when checking timing for valve adjustment and haven’t thought to mess with it as the van ran well.
I’m attaching a photo from 2022 (when I last checked) The crank position in 2022 is exactly where it is now after just re-tensioning the belt post head swap.
Was this something intended by the manufacturer and simply not added to the manual as a disclaimer or something unexpected to watch out for?
With the crank at the 4 degrees off, the van seems to drive well. Is this unique to myself or something others have noticed?
