I have a 1990 740 Wagon with B230 (non-turbo) engine with 180k. I have already cleaned most of the gunk from the engine that resulted from a bad camshaft seal oil leak, no bellypan and years of neglect.

At the present time, the valve cover is off, distributor is removed, valve lash has been adjusted, top timing cover is off, old timing belt is still attached. I do not have on hand the waterpump, tensioner, timing belt and lower seals to do the timing belt job now, but I will be doing it soon -- maybe in a couple of weeks. The camshaft seal is leaking buckets and I have a new valve cover gasket, valve hushers, and cam seal in hand. While I am here, I want to remove the camshaft to clean it up (especially the heavily varnished distributor socket)and check out the camshaft seal groove. I am hoping to replace the cam seal without removing the rear timing cover, if possible, since I will be back later for the timing belt. I have checked the fAQ, but I want to double check my procedure to avoid disaster.

1. rotate engine with the Harmonic Balancer nut clockwise to TDC #1 piston.
2. Mark the belt and cam sprocket to make sure the timing belt goes on the right tooth on reassembly.
3. Loosen the bolt holding the CAM sprocket and the belt tensioner.
4. Clamp the timing belt above the lower cover to make sure it doesn't move off the lower crank and intermediate shaft sprockets.
5. compress the spring on the tensioner and remove the cam sprocket and belt from top sprocket.
6. Break loose the cam retainer cap bolts. Back them all off 2-3 turns at a time to allow the cam to rise slowly. Keep the numbered caps in order.
7. Lift out the cam from the rear.
8. Clean everything up, change the hushers, lube everything when replacing it.
9. Lube cam seal ID and slip it onto the camshaft, leaving it about 2/3 in and about 1/3 out of its final position between the head and the front cam holdown.
10. Use a little hypalon at the mating surface of the front cam cap to seal the crack there and place the rest of the caps on.
11. Screw down the camshaft 2-3 turns at a time to lower it progressively.
12. Torque nuts to 14 ft-lbs. (Is this dry or with oiled nuts?)
13. press camshaft seal in the rest of the way 'till flush with front of head.
14. replace cam sprocket and torque to spec.
15. replace timing belt, release tensioner and tighten tensioner bolt.
16. Rotate engine a couple of turns and loosen then re-tighten tensioner bolt.

Have I overlooked anything in this procedure? Any warnings?
