Hey Dirty, looking good, Just be sure that the piece you removed from the end isnt the restriction that causes the jet pump to work. If the jet pumps dont work you will dump all the pressure your pump builds into the saddles and send none to the engine...

crap ! you think thats what they are?

i'm having a hard time visualizing the physics of the whole siphon thing.

isn't there supposed to be a small pin hole in the Y above the pump to cause the siphon effect ( just like on a vette), cause it seems that if the Y was fully open then the pressure would go into the siphoning tubes instead of heading to the regulator ( path of least resistance ).

guess i'll hold on to the little thingies juuuust in case

Im not exactly sure, all i know is if the ends pop off you dump all your pressure into the saddles and none will go to the engine. Thats what caused my nightmare...

more updates

i decided to make sure the pump is working so i dropped it in and hooked it up ,filled the tank with 10 gallons (i still have to put the sending unit gasket when it gets here) the good news is that it works the bad news is that the rails leaked , so i had to fix them ,,,, which meant new rail brackets and a new 90 deg -8 hose end on the back of the intake . sooooo ,,,, after getting my shirt soaked with fresh gas and having the garage turn into a giant fire hazzard , and at exactly 12:49 am 5th of jan 2011 it came to life

http://www.youtube.com/watch?v=OsFIAqghR-Y


i still have to verify i'm getting oil pressure , and still have to install the powersteering pump as well as other stuff , it still has a way to go before i can drive it , and even longer before it can be called done .

one thing it is for sure ; not quite

LOOOOL, cut me some slack R and F start looking alot likle each other when you just woke up

and the little dance wat the pattented happy Cha Cha Chaa dance

well now that i am sorta fully awake and the effects of the fumes wore off , i can reflect on last nights events

first off, when i came to add transmission fluid i found out that the transmission already had it! they shipped it full of oil , i'm sure that the shipping company would have reaaaallly approved of that

and since the only method i have for reading the oil pressure is through the stock porsche guage, i have to finish the mini harness as soon as possible in order to verify oil pressure.

I also just remebered that i didn't plug any of the ports on the intake manifold just behind the TB , which explains the high idle and surging i guess.


as for the cooling system , i'm still waiting on filling it up untill i get the porsche coolant sensor ( should be here any day) and figure out where to mount it . and i just bought som aluminum tubing which i'm planning on using as hard line under the car for the heater hoses as well as for the new routing of the A/C lines.

so next up :

-bolt in the power steering pump and the new hard line i made
-get a serpentine belt
-finish wiring the mini harness ( i swear this thing has curse on me , its just a few wires i have to connect but i always seem to find a way not to do it )
-fix the ABS wire that is cut on the driver side rear corner so i can get one more warning light to turn off ( i got a list for those too )


right now i just want to start it again and rev it just to feel good

I hear ya brother. Getting to hear her run is a major feel good moment. Glad to see that she fired up once already, of which is a major milestone in itself.

thanks guys, i worked on it abit more today , found a few oil line fittings loose ( forgot to tighten them) and i hooked up the oil pressure sensor . i also plugged the O2 sensor holes and fired it up again just to see if i got oil pressure ,,,, the good news is that the car sounded real good with the two holes plugged - just like a vette with an aftermarket exhaust , the bad news is the guage didn't register anything

i took the valve cover off and checked and it was dry , so i started it it again and let it idle for a bit but still no oil to the rockers .

i'll try to get a decent external guage on the engine and see what it says , if still no oil pressure i'll drop the pan and try to stuff the pump with grease .

i guess this is to be expected when you run an external oil cooler and remote filter while using -10 hoses to connect them to the engine .

i also got the power steering pump pressure hose made , and i should have it as well as the pump in the car by next time .

It takes a while (minutes) for oil to reach the top end of any LS block before mid 04. Driver side will be first & passenger side will receive oil second. Although, if you did not fill the pump w/ vaseline (grease) initially, it may have not primed.

If I recall correctly, the engine was bought used. So, it can't be a missed barbell fitting or freeze plug in the oil galley. If oil gauge sender is near the stock filter connection, you should see some gauge pressure within 10 seconds. As noted, the top end oiling takes a while. Where is the pressure sender located?
