LT1 Question on steam vent pipe connection...

I have an LT1 out of a 95' camaro and i have it carbuated. I am not sure exactly how to hook up the hose for the steam vent tube that comes out from the heads to the front of the motor on the passanger side of the intake. I have looked on line to see if i could get some help there, but i am not able to see a clear pic on how i need to connect it. I thought it was similar to a throttle body bypass but i am confused on if i need to hook the hose up to the little hose coming off the upper radiator hose or connect it with a T-fitting to the heater hose that drops into the top of the water pump near the thermostat housing. if someone could shead a little light on this that would be great!

Re: LT1 Question on steam vent pipe connection...

If you are using a stock radiator you can just plumb the line into the little hose running into the top of the radiator, LT1s usually dont get anymore air pockets than a reg small block. you do not need a pressurized overflow tank unless you are using a C-4 radiator.

Re: LT1 Question on steam vent pipe connection...

if do you have to have he manual bleeder valves in the waterneck (thermostat housing) and in the heater hose to completely get all air out of the motor? i don't have one in the heater hose but it is in the waterneck...

Re: LT1 Question on steam vent pipe connection...

I used the pressurized tank from a quad 4 achieva or the likes. I seriously doubt it would be a good Idea to run that line to the Cap puke outlet if thats what your saying. Also I usually drill a small hole in the thermostat to help water bleed the bottom end of air pockets. But there are other ways of doing this.

Re: LT1 Question on steam vent pipe connection...

Well i am not running the hose to the overflow outlet... there is a outlet under that one that it is connected to. i have an overflow tank on this motor as well. I just thought that you were talking about a different tank or something. I will take some pic today an post them on here to see if it is done correctly. I also thought that in the hose that comes from the heater core there is a air bleeder valve that is in the stock camaro... this is what i am asking about. when facing the motor from the front look at the water pump and it is the spout that is on the top left behind the thermostat housing and poins straight up. the hose that connects there i beleive has a rubber elbow and a alluminum section with this bleeder valve...

Re: LT1 Question on steam vent pipe connection...

Just see if that works. Thats not the way I did mine but it looks like it should work as long as you have an overflow tank (just noticed the line is kinked there). The fuel pump needs to be moved to the rear as the engine heat will get it hot enough to leave you on the side of the road... as well as they don't pull very well they like to push.

Re: LT1 Question on steam vent pipe connection...

well i have been working my way to the fuel pump issue.I was waiting to move it when i install the new sending unit into the tank. The line that you see being kinked isn't reallythe inlet to the overflow tank. it is the hose that drains the overflow when there is too much fluid pushed out of the system.I have seen this today and i have fixed it. in the last pic there is a hose that goes up from behind the thermostat housing and over to the fender that i believe needs a bleeder valve in it as well. i have seen some pics of what it looks like stock and i apears to have one in that section of pipe... It looks like it is needed there to bleed air out of the block part of the system and the one on the water pump bleeds it out of the radiator part. Let me know if you feel this is a wrong train of thought...
