Which shop did this?
Sorry for the delayed response ..
But basically, without the big bar that sits on the cams to lock them in
place when dialing in the timing belt, you will NEVER get the timing exactly
right on the cams and it will cost you some horsepower. This is a frequently
made mistake with independant shops, as people unfamiliar with how the cam
cogs "float" on the camshafts often will take the old timing belt off, and
put the new timing belt on with the same notches and everything lined up
roughly the same. On other engines, this is the normal method. On this
engine, it'll result in being off about half a tooth, which is several
degrees- for all four camshafts.
