3.8 DIS oil pump driveshaft
i picked up a hustle today on a neighbor's 95 windstar van, he bought it for 300 bucks it has a bad water pump, he started to tackle the project himself, he broke off two rusted in bolt studs and proceeded to remove the timming cover, well he made several mistakes he was trying to remove the cover with the harmonic balancer still in place and the oil pump shaft as well (dont ask), i jumped in and took over for some $$$, i got the balancer and the oil pump shaft out of the way, i have to remove the broken bolts, the darkness set in and ill have to continue tomorrow, my question is on the oil pump drive shaft there is a sensor, what is that? is that to set the timming? im aware of the fixed crank sensor, but by pulling the shaft, will i have to set the ignition timming? i have never seen this sensor before, then again i have vehicles with distibutors.

IF it is similiar to the 4.2, it sounds like the cam syncro sensor which is a hall effect switching device which signals the PCM to begin sequential pulsation of the fuel injectors (timed to #1 TDC, compression stroke). The oil pump intermediate shaft is engaged with the syncro assembly which is driven by the Cam gear. There is a tool to set the sensor correctly (54 degress counterclockwise from engine centerline) & you must note the direction the electrical connector on the syncro assy is pointed (before removal) & re-install in that position.
Hope this helps

It is basically like a distributor.. the electrical connector direction orients the syncronizer assy & the tool aligns the vane at the top (rotating inside the tube of the assy surrounded by the sensor itself). If adjustment is off (much) it may cause fuel injection timing problems (fuel injected into the wrong cylinder/wrong time).. I borrowed the tool from a local engine rebuilder (who had done some machining for me) to check mine).

camshaft position sensor
i found out this was the camshaft position i was dealing i wth, im done with the van, except this sensor, it times the fuel injectors, and requires a special tool to set, well i opened it up and its like the hall effect switch, and there is a blank in the rotor that passes through the pick up do i just line the gap and pick up on 0 dgress tdc? can i get it to run with out the tool?

I used the tool to time mine as I wanted to be sure but when I removed the two screws on top that hold the sensor to the syncronizer assembly, I found that someone had been there before me & had put white paint on the vane as well as the housing (both of which pointed at each other & by Mark II eyeball, I found this to be the middle of the opening in the vane centered on the opening in the syncronizer)). The sensor must be removed to insert the tool (note that sensor itself can be replaced without any re-timing ..etc being required). Same as installing a distributor, it is the syncronizer gear being meshed into the cam end gear that need to be correct. If you noted (marked well) where the electrical connector was before removing the hold down bolt you're halfway there.
The alignment tool (DIFFERENT ONE FOR DIFFERENT ENGINES) has a radial slot that surrounds the syncro vane and once dropped over the vane, the tool is rotated until the boss on the tool drops into the notch in the syncronizer - Steps:
#1 cylinder at TDC, compression stroke
Transfer the oil pump intermediate shaft into the syncro assembly ( if not already there;
Pre-lubricate the gear, thrust washer & lower bearing of the syncro assy with clean engine oil;
With the electrical connecter pointing at the mark you made before removing the assy,and the tool arrow (inserted in the syncro assy) pointing 54 degrees clockwise from the engine centreline, insert the syncro assy into its hole in timing cover (same as inserting a distributor, "leading" the gears on the syncro assy to mesh with the cam gears will facilitate the fully inserted position ending at the angle you want).
Tighten hold-down bolt
Insert Sensor & two bolts securely
Plug in electrical connector (see note)
Note: recheck the position of the electrical connector to ensure it is in same position as before you removed assembly- If it isn't, DO NOT loosen the bolt and rotate the syncronizer to reposition it - doing so will result in the fuel system being out of time with the engine and cause minimum poor driveability, & possibly engine damage. Rather, repeat the syncronizer installation procedure until connector location is in your marked position (sound alot like a distributor?).
I know you may not have the tool, but hopefully this will help your Mark II eyeball.
Good luck
