Ok so I just built my first ls engine, It is a 4.8l from a 2000 truck. It has a stock bottom end, comp cam and parts, An edlebrock victor jr intake with a carb on top. Has the edlebrock/MSD control box for the coils, head studs and the good layered gaskets. The problem I am having ithat it is pushing cooland out the cross over tubes that are attached to the heads. Can anyone tell me why? What did I do wrong? I switched heads to 862s, that had the back two plugged and only used the front two. Any help would be great. Thanks Brian

Did you make sure there was o-rings on before you installed it??

Yeah, there are seals for those tubes. Did you put new ones on? The seal has an embedded o-ring that goes around the tube.

Yes I put new orings on when I installed the tubes, the coolant is comming out the tube where the hose would hook on, does this need to be plumbed back into the radiator somewhere? I read on here it wzs just for vapor not coolant flow and guys were running it into a catch can.

Lol yeah its part of the cooling system.. It should hook up just below the reservoir line goes on the radiator..

Yea you need a 1/4 (i think) hose from that tube back to the radiator on the passenger side port
