Re: no oil to push rods

If you crank your engine with the DIZZY out, when putting the Crank on TDC, you must determine if it's on #1, or #6, they are both at TDC at the same time, But only one is ready to fire. You must check for compression with your finger at Cyl #1 spark plug hole.

BT doctor is write! Ive had engines take up to 30 mins to prime up ( Oil out every push rod) . Be sure to use a good drill a cheapy wont hold out LOL. Good luck

Re: no oil to push rods

When I build any type engine, I always use assembly lube and lots of fresh clean oil and cover everything as I build it up. That includes lifters, push rods, and rocker arms as well. Of course the entire lower end is equally covered in assembly lube as well. So the complete engine is lubed while the oil pressure does build up. I also made a oil primer out of an old HEI distributor and it works quickly too. I honestly can't see me spinning the oil pump for 20 minutes or more to get oil flowing through everything. That IS what assembly lubes are for. So I never had even one little issue or problem doing it that way myself...

To each his own, but I want to make sure there are no air bubbles in the passages so theres no chance of anything having a dry start.

Re: no oil to push rods

Thanks for all the advise everyone

i have ordered a oil priming tool online.
its to late to use assembly lube as it is all back together but i did coat everything in oil as it was installed.

Bt Doctur, I honestly understand what you are saying. But assembly lube is engineered for exactly those reasons. They keep all the moving parts properly lubed until the oil flows. If I had to ever spin the oil pump for 15, 20 or 30 minutes, something is wrong. I spin until oil pressure is readable and then fire it up. And I never ever had even one little issue doing it that way. Most engine builder do the exact same. Visit a machine shop and see. It usually takes less then a minute to get oil pressure on the gauge... Being how all the oil passages are not exactly lined up to there respective holes (crank bearings, cam bearings, lifters pumped up, and everything else), getting oil to flow in every area is pushing all that assembly lube out of place. I'd rather leave that assembly lube in place then partially oiled bearing surfaces... But like you properly stated, to each their own...

If everything was prelubed properly during assembly there will be no air bubble problems. That's what prelube is for. I use an electric drill with an oil pump drive from a distributor and run it at a standard drill speed rpm. By the way remember to spin it Clockwise Clockwise is helpful. Yes, I know this from personal experience. I was literally ready to pull and engine back out and rip that dang oil pump back out until a guy noticed my drill set on reverse. Nevermind that I had done this hundreds of times before. I attribute it to getting old. Getting old sucks. Avoid it at all costs.

Walt, I have to completely agree with you about the getting old part. I know it too well myself. BUT, it sure does beat the alternative... :laugh:

Re: no oil to push rods

Im with gm280. a good amount of assembly lube during the assembly process. I usually put the lifters upright in a small container and cover with oil to let sit overnight. that is enough to pre-oil the lifters prior to assembly.

On my last motor, I think my drill and primer may have made 5 revolutions prior to starting to build pressure, and maybe 30 revolutions prior to having oil starting to come out the lifter holes. a few revolutions of the motor while spinning the primer, and the rockers were being lubricated.
