priming a new turbo

[gsx20g]

I have just installed a new turbo in my car that has been sitting in my garage for 2 years (the car not the turbo). I've got everything ready to go but am trying to prime the turbo and am not getting any oil through the new SS oil feed line off the head. I was wondering if anyone has any advice as to where to start the troubleshooting? I disabled the ignition and fuel and cranked the motor to try to prime the turbo and nothing. Before parking the car everything worked fine but it has been a very long time. Just wondering where else I could check for oil pressure, is cranking the motor enough to get the oil pumping thru the feed line? Sorry for all the questions, but I am anxious to try and get this thing started! Any help would be appreciated! Thanks!

How long are you turning the ignition?? Is there oil in the car..... I just did the same thing. Just be sure that you are turning the motor over enough.

How long should I be turning the ignition?

do a search on priming turbo.. a few threads should show up.. i know because i was curious on what to do after i installed my new turbo..
i remember pulling a fuse from the fuse box in the engine bay.. and crankin it up for a few secs and it was done..

I've done the priming procedure but still no oil coming through oil feed line so I am wondering what else I can do to troubleshoot this problem. I also don't know how long this could take to see oil coming through the oil feed line to the turbo. I cranked on it off and on for about 10-15 minutes and saw nothing, should I continue to do this (am I not giving it enough time for the oil to flow)?

Well, the only other thing that I have had happen to me is an oil pump seize. My 93 AWD oil pump seized for no apparent reason and ate the teeth off the BS belt. Other than that the only other thing I would check is for oil leaks...or maybe a blockage in the line. But I'd pull off the timing cover and check to make sure the belt is spinning like it should. I know that this is rare...but it has happened to me and i'm sure it has happened to others. Let us know.

Well, I checked to make sure the oil pump wasn't seized and it isn't so I guess I'm going to check if there are any clogs in the lines. What would be the easiest way to do this? Thanks for the help!!!!!!

Well the first thing i would check is the seating on the banjo bolts and crush washers. These can lead to some of the best oil problems. If the line isn't right you'll get no oil. Other than that just start checking the lines back...see how far the oil is making it...if it is making it anywhere... WTF

Just a quick question. I don't want to get off topic but do you have to prime a used turbo? Like swapping a 14b from a 1G to a 2G?

 

[Hammer_Gaidin]

I'd prime it no matter what. Just to be safe.

You can just unbolt your feed line and pour some oil down the turbo while turing the impeller.

After sitting all winter, i started my 2g a few weeks ago and the oil light was on and there was no oil pressure showing, well i figured that maybe a critter had chewed through the sender wires, so i let it idle for maybe 20 seconds before turning it off just to be safe. During this time of course i never revved it at all and never heard any tapping noises. So i checked everything and then started it again this time with the oil cap off to see if the head was getting any oil, looked in and nothing coming from the lifters no oil splash nothing. But there was no lifter tick either so i figured that would be the first sign to kill it. so after another 20 seconds of this i shut it down again, and looked some more stuff over and found nothing wrong!!!. I could'nt figure it out since it was fine when i parked it. So i start it up a third time, again no revving it and no pushing on the clutch while its running just in case, the oil cap was still off and i was outside looking into the cams spinning and then i heard the engine bog down a few hundred rpm's and heard oil starting to get pumped (weird coughing noise from the head, like when you pump oil from a drum and its getting some air in the oil, and no it was'nt the bearings or anything) anyway within a few seconds oil is squirting like it should from the lifters onto the cams and the oil light was out. So i'm thinking that the oil pump lost it's prime big time for some reason, i still dont know why but that might be the case with your car. If you dont find anything then maybe try the same thing as i did. but make sure there is some leftover lube up top (dont try it with dry cams or anything) and make sure it is full of oil, then let it spin some more, about 20 seconds at a time with like a 20 second break in between. It might just take a while to get the oil pump to prime in your engine, like mine did. It drives fine now btw, just like always.

Also, i'm not telling people it's ok to run their car with no oil pressure either (defiant) . !
