I have a fresh rebuild 350 4 bolt main. When i fired it up i had 80+ psi instantly but no oil at the top of the engine. I checked for the plug that people always say to check by the distributer and it does appear to be ther. Any ideas would be appreciated on what to check or what would cause this. I did notrun the engine very long 3-5 seconds. Didnt want to ruin anything.
Thanks in advance.

 

Did u change up the oil pump to a high pressure one cause if not the yes u have some sort of blockage some where...... Did u have the valve covers off when the engine was running and see no oil on the valve train .... If the motor is fresh it will take a little bit time to pump up the new lifter before u see oil on the top end maybe a minute or so.....

 

I agree, you definitely need to give it a little more time to distribute the oil. If that 80# of pressure is anywhere close, your lower end is protected.

 

It is the original oil pump installed and I did have the covers off to see there was no oil coming up. I pulled the engine to check the lower end and it all seems to be ok so this weekend I will put it all back together and try to prime ot for alot longer. Hopefully I just didnt give it enough time.
Thanks

 

You might try leaving the Spark Plugs out of it, and just spinning the engine just with the Starter for a short while. That may help get things primed, where it won't take so long to show up.

 

I used to have a old distributor that I took the cam gear off and used it on a old electric drill and spun up the oil pump with out turning the motor over and once and while spin the motor over and repeat.....

 

HA, that's a pretty cool idea !
From my experience in testing Oil Pumps with an Electric Motors, it is amazing on how much horsepower they absorb. Additionally, I can see the value of using that adaptor, to be able to tweek the Oil Pump shaft, to re-stab the distributor.

Better watch it though...
If you come up with any more ideas like that, you could be eligible for a Master Shadetree Mechanics License.

 

I build alot of race car motors yrs ago and u pick up little tricks.....
