How to do safe start after replacing timing cover? (oil)

My engine is empty on oil after replacing timing chain/cover.
There is some sort of grease in the oil pump.

And my plan is to fill new oil filter with oil and install it. Then oil on the rocker arms, and fill up the engine.
Do short turns on the starter, without coil wire, so it doesnt start but pumps oil.

Run 30 minutes or less, then replace oil and oil filter.

Good or bad plan?
Should I run on starter until I notice some oil coming up on the heads?

 

I cant find one for Buick, will Chevy tool work?
Moroso 62200

 

You recommended moroso but my local store have replaced it with Proform #66896 which have some extra parts on it. Good reviews on Summit, by Chevy people. Do you think I would regret buying this one instead?

 

You can rent the prime tool from autozone. Well at least the one here had it. Worked as it should've.

Put oil in the filter. Pour oil on the rocker arms. Prime the pump--or not. Your choice.
START THE ENGINE
Don't bother changing oil until it's actually due for an oil change.
You're making this WAY more complex than it needs to be. GM built eleventy-million Buick engines, and didn't prime, or crank-without-starting any of them.

 

Im with Schurkey, you only pulled the front cover. Oil is still in the engine. Just pour fresh oil in it (over the rockers if you wish) and It will be fine. Its not an engine break in...No need to change the oil again after until its next due

In the 1972 article that named the 1972 GS as the performance car of the year, one thing that Buick did on their BBB on the assembly line was use a rig that injected air into the cylinders and "air ran" the engine and checked for pressure and did some ops checks on the engines before they passed assembly. That may have little to do with the prelube discussion, but I think it is interesting Buick doing a QC check like this. They did that check for a reason, maybe because they wanted to ensure oil pressure or not, but interesting nonetheless.....

 

I built my own priming tool. Deep 1/2"- 1/4" drive socket($4 at auto zone) with a 9" extension. Drilled the end of the socket and drove in a roll pin the correct size. Then ground the pin down down smooth on the outside. Worked like a charm. 1/2" electric drill spun the oil pump right up to 50+ psi in just 3-4 seconds.

 

Very slick.:TU::TU:

 

I must confess, I got the idea from a post by 70gs4spd. He built one similar but with a standard socket. I figured the extra length of the deep well would not allow it to fall sideways into the engine if it came off the extension. Thinking back, if you use this method you should use electrical tape to hold the socket to the extension as a safety. Foreign objects would not be cool.

 

Im worried that some dirt fell down oil cambers on the heads, and down the open pan during 4x attempts to replace timing cover, drilling and installing new threads, and so on (I have flushed the oilpan with diesel, vacuumed the chambers several times and used a magnet to find metal chips) so thought I could flush the engine with some cheap oil and then run my JoeGibbs oil as a final precaution.
But perhaps better to go joegibbs directly and avoid having cheap oil mixed in it.

 

You seem to have done what is possible to eliminate the "dirt" and metal chips. I might change the oil filter and top-off the oil after twenty minutes of run time; but I wouldn't change the oil.

 

I have never replaced an oil filter without changing oil but it sounds good now when you suggest it. (I have an extra 51258 oil filter and bottle oil.)
I filled it with JoeGibbs oil and pumped with priming tool yesterday.
It was dark so I’m not sure if all valve springs received oil. Should I turn the crankshaft now and then during priming or should oil come to everyone all the time?

 

If you spun the oil pump with a drill, and it bogged the drill down, your done, good to go, fire it up and do burn outs:TU:

 

If you really want to confirm, you can pull the drivers valve cover and watch for oil seaping from the rockers. The drivers side gets oil last
