rebuilt engine first start up

[ka-t 300]

Soon I will be starting up my freshly rebuilt forged motor for the first time and i'm just trying to figuire out if you have to like prime the oil pump or fill the oil galleys some how or any thing special before the first start up to to help with quick oil pressure or do you just start it up ?

i usually use a funnel attached to hose to pour oil into the outer ring of the oil "tower" to put oil into the oil pump. This seems to promote a quicker flow of oil from the oil pump.

Alson, are you saying you use a funnel to pour oil into the galley that starts on the oil filter/distribution block and runs to the output of the oil pump? If so thats a really good idea. I doubt its needed if you prime your pump with the injectors off though.

OP - All i usually do, is crank the engine over with the injectors unplugged for about two 10 second intervals so the pump puts oil through all the galleys. Then plug the injectors back in and fire it up.

Tons of assembly lube should have been used. If so, then do what 480 said. Turn it over with no fuel for 5-6 seconds at a time. Do that 3-4 times and you'll have oil everywhere it needs to be.

Then add fuel, restart and immediately look for oil pressure...right Nate

After you see that you have oil pressure, inspect for leaks etc. I idle for 15 minutes at a time.

For break in I subscribe to the "drive it like you stole it" method with lots of high vacuum decel and no lugging. Use regular oil to...the cheap stuff. Since you'll be changing it a few times and it promotes ring wear better. You might wanna look into actual break in additives. I've been hearing some stuff about these lately that seemed to make sense. Was on Hot Rod tv or something...

Lol i had cold oil pressure, albeit less than i should have had but not enough to raise any flags for me at the time.. FTL.

im with what WD said.... you should have used plenty of assembly lube. what i do is disconnect the fuel pump fuse, and crank it over for 10 secs. then plug the fuse back in and voila! make sure you do alot of deceleration to pull vacuum. this will help quickly seat the rings.

what ive always done with my motors is ring it out through every gear but not real hard because i always put new clutches in, and once i get up to about 70 or so ill just decel to 20 mph or so, and do that a bunch of times. i wait 200 miles for clutch break ins. then its time for some clutch kickin .

good luck and have fun!

Putting oil into the oil pump before priming seems to shorten the time that no oil is being pushed through the motor once it is started or turned over. This will help prevent damage if either the top or the bottom was rebuilt and assembly lube was not applied to both. I have also seen some worn oil pumps on KA's not prime or delay circulating oil for an extended time period because there was no oil in the gears. Just a suggestion of a small step to potentially avoid other problems.

jump the started solinoid so the motor will turn over for a couple of seconds without gettign fuel or spark ,then go ahead and start her up

or you could just unplug the fuel pump fuse..... a whole hell of alot easier. no fuel... no fire.....

brian, i didnt even realize this was your thread LOL. good luck with droppin that bish in. what are you doing with the ka that came out of it??

yeah hey I finally got it droped in there got it oil pressure @ idle is 38 but im'm runnin lean as hell i turned my apexi neo up to 50 to get it to read 17-18 on afr ? it ran fin with the other motor in there. compression ratio is 9:1 instead of 9.5:1 would that make a difference ? also when I pull the tps conectors to set timing it speeds up a little then dies ? so i need a little info here diagnosing this thing.

as far as the old set up I I used all the old turbo stuff but the block is in good shape as i pulled it before anything went wrong compression was 180-185 with no leak down . n ot sure what i'm going to do with it .
