Guest pintoz Posted April 20, 2004 Share Posted April 20, 2004 Tomorrow I finally get to pick-up my l28et motor and I have a question which my machinist was stumped to answer. This was the first motor he ran across that he isn't sure how to prime. Is there anything special I can or have to do to get oil where it's supposed to be. Besides the crank and cam, my other big concern is my new (rebuilt) hybrid turbo. I don't want to mess anything up before I'm able to put the thing in first gear. Thanks for your help.

fl327 Posted April 20, 2004 Share Posted April 20, 2004 Pull the coil wire off, pull off the oil drain hose under the turbo, put a bucket under the hose, crank engine until oil comes out of that hose, oozing, nasty-turbo is primed. Slip it back on, clamp it up. Crank it again without coil wire hooked up for 5 seconds or so. Ok. Start it up and keep the rpms around 2500, yes. Check everything or have a friend do it and dont let it idle for 20 minutes or so. Take it for a light cruise, check everything again. Park it and compliment yourself over and over again, possibly cwalk if youre talented. Quote Link to comment Share on other sites More sharing options...
Guest Zachb55 Posted April 20, 2004 Share Posted April 20, 2004 you know to prime the oil pump too, right? you may have to pull it off to get oil inside of it to start the priming up... also, once your pump is primed, to prime the whole thing without turning the engine over you can pop off the dizzy and take a drill with a long flat-head screwdriver extension and prime away (the oil pump drive shaft must be removed to do this, and then replaced before starting, of course). i wasnt sure if you knew that or not, but now you do! -Zach Quote Link to comment Share on other sites More sharing options...

JMortensen Posted April 20, 2004 Share Posted April 20, 2004 I don't know if this is the "correct" way to do it, but I bet you could pack the pump with vaseline, then crank til you have oil pressure with the coil wire disconnected. The vaseline will just provide the pump with suction to pull oil out of the pan. Works for Toyotas. I think when I did my Z engine I just filled the pump with oil before starting then cranked for a while till I got some pressure, but it took longer than I expected.

Drax240z Posted April 20, 2004 Share Posted April 20, 2004 It can take a long time to prime the oil pump by cranking. (a loooong time) Pull all 6 spark plugs while you are doing it. Hopefully after spending a whole pile of $$$ on getting your engine rebuilt you've spent something on a decent oil pressure gauge too.

z-ya Posted April 20, 2004 Share Posted April 20, 2004 It can take quite a while to fill all the oil galleys in an L6 block. I take and old L24 distributor and shaft. Take the drive gear off the shaft, and install it, along with the oil pump, in place of the one you plan on installing permenantly. You can press the gear off with a press, or you can do it with a vise. Take the advance mechanism out of the L24 distributor, and install it in the engine. Put your 3/8" drill on the distributor shaft, and run the drill backwards (CCW). You will notice at first that the drill isn't working too hard, that is untill the oil gets to the pump, then you will hear the drill start to work. Have the valve cover off, and once you start seeing oil come out of the holes in the camshaft, you are done. Remove the L24 distributor, and DON"T FORGET TO REMOVE THE SHAFT WITH NO GEAR! If you forget to remove this shaft, the oil pump and distributor will not turn. Install the oil pump and shaft (with gear) as per your favorite manual. I've done this on three L6s, and it works great. Pete Quote Link to comment Share on other sites More sharing options...
Guest pintoz Posted April 20, 2004 Share Posted April 20, 2004 Thought that only worked on a Chevy? Yeah, I thought so too. Well z-ya, I like your idea. Finding a L24 oil pump and distributor at a junkyard around here might be next to impossible. I guess if it comes right down to it, I'll just crank. Is it a good idea to put a little oil in the cylinders before/during cranking? Quote Link to comment Share on other sites More sharing options...
z-ya Posted April 20, 2004 Share Posted April 20, 2004 Any L6 distributor, shaft, and pump will work. I just happened to have an L24 on hanging around. Pete Quote Link to comment Share on other sites More sharing options...
Guest pintoz Posted April 21, 2004 Share Posted April 21, 2004 OK, that just might work. I have a spare n/a motor just hangin around. I'll have to look into that. Thanks Pete. Quote Link to comment Share on other sites More sharing options...
