308 2v timing question

Are you sure that you are on the PM1-4 mark? If it's actually the PM5-8 mark, the 1-4 cams would be rotated by exactly 1/8 turn.

 

Without going through the hassle of doing a full degreeing of cams here is what I recommend you do.

1) Replace the belts, looking at the cams from harmonic balancer end put the cam alignment mark close to the left side of the cap alignment mark(this is the wider mark)

2) release the tensioner - i.e put tension on the belt

3) complete 1 full rotation of the engine by hand back to TDC

Now check the alignment of the cam marks with the cap marks at TDC

If the cam marks are within the cap marks no need to do anything with the cam drives, just lock everything in place and now look at the dizzy, i.e goto 4, if the cam marks are still outside the cap marks goto 6)

4) Mark cylinder 1 contact point on the outside of the dizzy to cam metal plate.

5) Move the flywheel to AF6 mark - now the rortor should be nearly aligned with the mark on the cap, if not you need to remove the dizzy from the head and reposition it so that one of the splines gives you better alignment with cylinder 1 contact point.

6) (Make sure the flywheel is at TDC before progressing) - Only do the following with one cam at a time - If a cam mark is outside the boundaries you need to start playing around with repositioning the cam drives so that you do get them aligned inside the cap guide. This is not rocket science just slow and time consuming and involves firstly removing the nut at the end of each Cam (careful you will need someone to help you if you do not remove the cam from the seats, or the cam may turn dinging your valves, best doen with an air gun and a strong friend)that holds the cam drive in place and removing the dowels underneeth this nut that holds the cam drives in position on each of the cam shafts. Now set the cam with the marks centrally aligned in the cap mark, find a dowel position that allows the cam and the belt teeth to align in this position and lock in position, lock the cam nut( with your strong friend). Put the belt on, re-tenison the belt, complete 1 turn and check at TDC the mark is still within the cap mark. Complete again as necessary on all the cams until within spec.

7) If after completing 6) your dizzy is still well away from the mark, complete steps 4) and 5)

Hope that helps - easy when you have done it!, difficult to explain in email!

 

You probably know this, but the 1-4 bank is the rear bank, the 5-8 bank is closest to the front of the car. With the engine on PM1-4, the 5-8 distributor will be 45 degrees off.

 

The flywheel can only go on one way. One of the flywheel bolts is out of position relative to the other bolts in the circular pattern. If you pull the flywheel, mark it & the crank to speed reinstallation.
