Question re: distributor drive gear. The 1600 is assembled and close to a bench start. I'm in the middle of changing from 009 mech. dist. to an electronic vac. advance . I've set the #1 piston to tdc on the power stroke , removed the old dist. Now from what I've read , the slot in the top of the drive gear should be at right angles to the case with the bigger half to the front. Mine appears to be off by about 15degrees forward. I'm not sure what to do? Bob |

The drive off a little bit is quite common. If it is off a lot from the picture in the Bentley manual, than the drive is likely installed a tooth out and will have to be removed and re-indexed. I would install your distributor, and see how things line up; specifically does the vacuum canister end up in a good spot when the rotor is pointing to the wire leading to number 1 cylinder. Not sure if those aftermarket distributors have a line engraved on them that equates to number 1 cylinder. You could temporarily install the original one, and see if things line up...

Hope this get through , I've had trouble login in. I installed the dist. as you suggested , and the only way it will fit is with the rotor now pointing to the #4 cyl. position - that will now be the #1 post on the cap.
I've been trying to send a photo , but it tells me the file is too big.
Now onto oil pressure -Topped the crank case with oil , removed the plugs and the oil sensor and wired the starter , cranked the engine and no sign of oil from the sensor port. Got a couple of things to try.
Thanks for the support Bob

Photo did not work. How long did you crank the engine over for? Was the oil pump primed at all?

Oil relief piston stuck/missing or spring too short?

Probably cranked for no more than 15/20 seconds - a little leery of doing damage. Didn't prime the pump - not sure of the procedure .

I've removed the oil relief valve closest to the pump it took a bit of work to get the plug out and appeared to be scarred. I checked the pump gears for backlash and they seem to be within spec. One thing I noticed on the inside of the pump cover was a slight scarring made by the gears. Spent most of my time looking for the 10 mil socket - it'll show up tomorrow.

If that oil piston is damaged it can stick in the bore and bleed your pressure off. Clean up that piston or try a new one and see if you can get pressure. FYI I made a pre oiler out of a pump up garden sprayer. Cut the wand off and used a 1/8 npt barbed fitting in the case added a couple litres of oil and pumped it up gave a couple turns of the motor.

I cleaned up the piston , it seems to slide a lot easier. Primed the pump ( a bit of grease and oil) , cranked it over and got oil flowing from the sensor port. I retuned the sensor and hooked it to a bulb and a battery and when the engine cranked a couple of times the light went out. So check that off the list. Thanks for the support guys ,I'm giving it a bit of a break , apparently there's some house , yard and gardening projects on a list.
