Problem with new long block

[sleepercobra]

Car fired up today great, no problems. I go to the gas station to fill it up because i was on empty. On the way home the oil pressure falls all the way down. Wtf.... I check all the wiring when i got home and even went out to get a brand new oil pressure sensor. After i replaced that it did nothing. I replaced the oil filter also nothing. What could it be? I hooked up 2 different autometer oil pressure gauges and they both read 0. Could it be the oil pump on a brand new longblock or am i missing something??

i dunno but this car is costing me more to fix then its worth lol im thinking maybe some kind of gunk got stuck in the pickup tube?? i guess i will drain the oil tommorow...

not sure if it is related or not, but on modfords there were guys having oil pump problems in new long blocks.
Not sure of the cause, it was months ago, but maybe something to do with the crank position in the block.
Check where the crankshaft comes out of the front cover for contact marks.

i dont think thats it, i popped my oil cap off while the engine was running and it almost sucked my hand in. what do you think could that be? i put the cap back on and took off the pcv filter on the drivers head and it seems like the blower is sucking in air from that one port back there and when i plug it the oil pressure drops all the way.... now im really stumped.

call whoever built the motor.
No oil pressure is serious

figured out it was because of pcv. put a breather on my passenger side and all is good. I didnt think the pcv from the blower sucks that hard from the drivers side head that it would kill oil pressure. weird.... anyone have any suggestions on routing it or maybe slowing down the vaccum because on initial startup its not rising as quick as it should?? im using a jlt pre pcv filter. maybe go back to stock?

Are you sure everything is hooked up properly?

There is no PVC on the passenger side from the factory.

 

[sleepercobra]

100% sure. right now im only using a jlt pre pvc filter on the drivers side and just a breather on passenger. is it suppose to suck really hard from the blower on the driver side pvc??

Its supposed to suck cause its under vacuum.

Are you telling us that there is no PCV valve on the drivers side, just a pre-whatever is on there?

the pcv is there but im using a filter on there instead of going with an oil seperator.

Is the hose from under the manifold kinked in any way? Im not even sure that would cause the problem..just throwing out ideas.

Looks good as far as i can tell. But i just swapped out pcv valves from ev-153 to ev-253 and its perfect now.

Cobras use EV-111 from the factory FYI

im pretty sure from factory its ev-153. i searched all over and asked 2 different ford dealers.

You may be right. Maybe the EV-111 came on Super Coupes. I am lucky to keep half the info i take in straight!
