When Andrewh and I prelubed the Imperial it simply wasn't possible to get to the crank well enough to turn the engine over. After we built up oil pressure we jumped the starter relay and turned the engine with the starter.


This is actually how I do it all the time. And if you use a remote starter button at the relay you can actually keep the drill running while you turn the engine over.

Again, thanks for all the tips and info everyone!

I have another stupid question. If I prime the motor one day, then wait a few days or a week or whatever to start the motor, do I have to prime again before I start it?

In other words, does it all drain back down requiring me to reprime if I don't get to starting the motor for awhile? Or, is it primed once it's done once? Thanks!

Do you reprime after you have left a running engine sit a few days?????

That's what I thought but something about firing up something I've got $4000+ into and get be wrecked with one wrong move makes me overly paranoid.

How much is invested other vehicles that are left sitting for days and months on end???? Yours or other people. Vehicles sit for long periods and fired right up.

Looking for a way out of Middl...
To me the reason to rotate the motor has always been to get the oil to the valve train since the valve train is only oiled once every two rotations.


These are things I do while it is still on the stand.

I have always pre-lubed the valve train with moly breakin lube (just like the bearings) and filled the rocker shafts with oil from a pump oiler. I rotate the engine while assembling it until the #1 (or #2 depending on the side) intake AND exhaust valves are closed. I remove the front rocker shaft bolt and fill it with oil.

I set #1 on compression TDC and make sure the cam is lubed crazy amounts. I don't rotate it after that if possible.

Once in the car you will have to rotate it some to get the Convertor/clutch installed but still I limit that if possible to keep the cam as covered in lube as possible.

Make sure it is at #1 TDC Compression again if rotated. Then just before I start the car I pre-oil it with a hex rod, not turning the engine over. I only do it long enough to get pressure. No need to flush out the breakin lube. I drop the dist drive in and set the Dist to fire at #1 terminal and rotate it to just break point/reluctor contact/alignment.

Prime the carb with electric pump or squirt gas in the bowl vents and be sure the accelerator pump is pumping gas. They start up right on the spot with littel turing over and once I am sure the oil pressure is OK, ~2 seconds, I run it to 2K rpm's and leave it there for 20 Minutes.

Never had a cam, valve, or bearing problem.

BE SURE TO RUN GOOD OIL. NOT THE LOW ZINC JUNK THEY SELL FOR MODERN CARS.

OK guys I have another question after priming it with my drill and hex tool. I got decent oil pressure to show up on my gauge pretty quickly.

What I'm wondering now is shouldn't I be seeing some oil showing up on the top of my heads somewhere with the valve covers off while I am doing this?

I had the drill spinning CCW and I tried rotating the motor over by hand to different positions several times. My passenger side head looks dry as a bone and my drivers side head looks oily (but I can't tell if that is from when I added the oil).

If it makes any difference, I am running the 440source rockers and 7 quart pan (with 7 quarts added).

Thanks for any advice!

turn it till the dist rotor is at #6 w timing marks at TDC & run the drill again & see if the pass side will now oil

Pull all of the spark plugs out and remove both valve covers, start priming the motor and while priming it turn the crankshaft over clockwise very slowly until you hear the drill motor noise change, that is when the oil will be going up the oil passages to the rocker shafts, one at a time Once the drill motor sounds different stop and let it run the oil in the shafts until you like what you see or when it starts leaking onto the floor The rocker shafts are oil once every camshaft revolution or once for every other crankshaft revolution I now have my camshafts grooved all the way around on the number four cam journal so they will oil the rocker shafts full time lots of warnings on this post, some are valid and some are internet myths

OK, I got oil coming to the top now. The key was to have my wife working the drill while I turned over the motor by hand at the same time. Thanks for walking me through this everyone!
