i took it off today and used the block off plates for an LS1 that alex gave me, the one for the intake was like a MM or 2 off so i had to cut a lil bit of the plastic off this one thing to make it fit. i sealed it all up and everything then after it was all done kasey was liek start it up! i debated it for a second then did it, the squeal was still there
the only thing that i can think of is either the block off plate leaks cuz it wasnt sealed correctly, the driver side exhaust manifold gasket leaks or worst of all the head gasket leaks :-/ for those of u that dont know the noise it makes, its like a high pitched squeal and it dissipates after like 30 seconds...
