Checking Valve Timing
WARNING: This page is about a different car, the 2001 Mazda B2500. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION:
Always rotate crankshaft in direction of normal rotation (clockwise as viewed from front of engine). Reverse rotation may cause timing belt to jump time, causing engine damage.
- Remove 2 access plugs from timing belt cover. Rotate crankshaft clockwise and position No. 1 piston on TDC of compression stroke. Ensure crankshaft pulley TDC mark aligns with mark on timing belt cover.
- Looking through access hole in outer timing belt cover, ensure camshaft sprocket timing mark is aligned with inner timing cover pointer. See Figure. Ensure diamond timing mark on oil pump sprocket is aligned with timing mark on inner timing belt cover. If all timing marks are not aligned, remove timing belt, properly position sprockets, and timing belt reinstalled.
