I just got to the point today where I figured i could hit the starter and at least prime the oil system. I cranked it a few times for ~4-5 seconds, but never saw the oil pressure gauge leave 0 psi. Not even a bump. I checked the oil pressure sender, and it's not broken off, and is plugged in. I know I installed the oil pickup tube right, o-ring and all.
Now, I know I put 5 quarts of oil into it to flush the system. And since there's no big puddle on the floor, I'm sure it's still in there. But just to be thorough, I pulled the dipstick to check the level. Another problem, I had to two-hand the dipstick out, and when it came out, it looked like a great big capital J. Apparently, it had a disagreement with the crankshaft.
Needless to say, it's been a wierd day.

Anyway, can I pull the oil filter and crank the motor (with a catch tray under there, obviously) and see if I have oil pressure? I don't have the fuel injectors plugged in yet, so I can't hurt it by running without oil.

Any other ideas, about the oil pressure, or the dipstick? Is there some thread out there about this, that I forgot to read??

i remember when i did my h/c install i fired it up and was looking at the temp gauge and freaking out that there was no pressure. needless to say there was. it was a sign to go to bed. late nights after school.

well i doubt you are going to build pressure with the starting spinning only. you need to pump oil to the top of the motor, and the 100 or so rpm the starter spins at is not going to do it.

Yes it will. It should build 20-30 lbs with the starter.

your probably gonna have to spin about 15/20 seconds.
then you should have pressure.

First question that is crucial before you do start it.

Is the front oil galley freeze plug installed? (Its under the timing cover so if its not reinstalled by machine shop, it will pump oil right back out the front of the motor and you wont know why you dont have oil pressure when you start it.)

If not, youll wipe out the bearings within 15-20 seconds after firing it up. Its happened to a few guys I know.

Other than that, I almost never get any oil pressure just cranking it over with the starter, usually ill crank it for 10-15 seconds, then start it up and get oil pressure about instantly.

Id suggest pulling the spark plugs so you dont beat up the starter and itll spin faster. My buddies motor took damn near a minute and a half to prine with a drill one small block ford. Unfortunatly you cant do that on an LS1. If your sure every plug is in place, id pull the spark plugs and give it a good 10 second spin with teh starter. You should see a little pressure that way.

Allright, I PM'd Brian at SDPC, where the block came from to see if they install the oil gallery freeze plug. I think it was there, but it's been over a month since I put the timing cover on so I don't remember with any certainty. Now I gotta figure out why it tried eating my oil dipstick...

Mine never built pressure with the starter, but once I cranked it, it was there after a few seconds.

pull the plugs so there will be minimal pressure on the bearings, you will have to turn it over a few times to get it too build up...dont try to do it all at once, crank 5-8 seconds at a time

Here's my dipstick:


At least that explains the quiet "twang" I was hearing when I rolled the engine over installing the torque converter... It definately didn't sound like the ticking people seem to always describe, now I know what it was LOL

That's crazy. Never seen that before. Did you start it up and get oil pressure?

pm noyzee, his 402 alomst sucked his dipstick in, dunno what he did for a fix though

regblkss

i did the same thing on my 402 its inthe back of the block there is a dumb bell looking thing that controls oil pressure. its not installed.

regblkss

bad thing is you have to remove trans and rear cover to check it out. no one told me about it before hand. if you have your old block you can see it.

If that's the little white plunger looking thing behind the oil filter, accessable under the rear cover, it's installed. I made sure to check that.

Where did you buy your 402 from, just out of curiousity?

V-10 Killer

Well, I just checked with SDPC about that too. That's installed before it ships, and I remember seeing it there, so that's not it. I guess I'll just hope I didn't crank it long enough.

regblkss

tsp love it makes ton of power.

regblkss

did you washers to space the windige try it might be blocking of the pick up tube. and dipstick got in between the crank and the try.
