When I got my car it already had a set of adjustable cam gears, zeroed out. I don't know if any internal work had been done to the car, but it has 135,000 miles with 190 compression across, so it seems as though a rebuild could have been in its past. When I had some cam angle sensor issues, I replaced the timing belt. In doing so, I realized that belt had previously been installed to make it so the cams would be angled in toward each other (I.E. the exhaust cam rotated 1 tooth clockwise and the intake 1 tooth counter-clockwise). Not knowing why this was, I installed the belt just as the Vfaq stated, with the timing marks lining up, and now my vacuum sucks. I pull about 14 or so in/hg of vacuum at idle, give or take about 2 in/hg. Could the cam angling be associated with the problem?
 
Ok, so it could probably fix the problem if I angled in the cams, but why is it that at the stock angle setting I'm pulling such low vacuum? When the car is cold and I just start it up (in the morning) it sometimes goes as low as 10 in/hg.
