Vacuum hoses

So i bought my car last year and the motor blew not long after, i bought a used one and worked on it all winter to make it good, i dropped it in the car and plugged everything in, now i came to put the vacuum hoses as the diagrams i found on the internet said but the hose holes are welded in, i found the guy (that i bought the car) old forum and found picture of the motor when it was in the car and running

Any idea where the hoses go ? and what can i do to make my engine run, it cranks but doesn't start, everything is good, spark good fuel good batterie good

 

that's what it used to look like in the bay

 

Most of the hoses on top of the throttle body are for the EGR system and EVAP system, which looks like they were completely removed. Which vacuum hoses are you talking about?

 

the ones on the valve cover

 

I believe in stock form, both are for positive crankcase ventilation. The one at the rear starts with the PCV valve in the valve cover and goes to the intake plenum next to the throttle body at the back. The one in the front connects to the front side of the throttle body. With a supercharger those lines are most likely modified.

 

thanks, mine are clearly modified, as the brake booster hose goes in the front side of the throttle body, do you have an idea as to where the from the front valve covers goes?

 

try this 2RZ & 3RZ Low Boost Supercharger Instructions - LC Engineering
or this 2RZ/3RZ High Boost SuperCharger Instructions (.PDF) - LC Engineering

 

Thank you very much, i just went through it and the diagram at the end does not show where the breather vacuum hose needs to go, do you know where it should go?

 

page 13 of the high boost instructions say to connect it back to the front of the throttle body

 

But where it should have gone on my sc it has been welded shut as the photo shows

 

I suggest you call LCE and talk with one of their techs. They are the experts on the 3rz supercharger.

 

Good idea thank you
