The cams are timed on the std marks, those in the rear of the cams -I didn't use camblocks, although I'll try them on possibly this week.
I set idle to 1000rpm and its rock solid -still unmapped. After mapping I will see how low I can get it to idle regularly.
This is the maf sensor the 164Q4 uses as std and its there because that's the system I use now (Bosch M3.7.1).
For the time being, I have an urgent job to do as I just averted disaster...

Noticing a little slack on the belt, I checked the tensioner and it crapped out right then and there while I attempted to adjust it!

Unbeleivably enough, it got me home before it failed! I took the thing apart and will convert it to a manual adjust by cutting threads in the bore and inserting a long bolt + locknut, a sure-fire solution. Will have pics in a few days when i'm done.
