Pro-x 330 Cylinder Leaking Coolant

[RayWilt]

I have a pro-x 330 cylinder and is leaking coolant between the sleeve and the cylinder at the top of the exhaust bridge. Has anyone ever had this problem and how do you think i should try and fix it.

How bad is the leak or how big is the gap? Got any pictures? Alumi-seal is a far shot for something to work. JB Weld probably won't hold in the water jacket either if its too close to the exhaust, it will just melt. If its a big gap your looking at removing the seal, welding/boring excess, re-installing the sleeve and checking for warps.

Had that problem with an ESR 330 kit. Added cooling system stop leak as per ESR recommendation. Worked just fine.

i've tryed some of the leak stop stuff helped but didnt stop it. The gap is not big and it only leaks when it getts warmed up so that the coolant is presurized cause of the heat.

I used Wynn's brand. It might be hard to find, but it is some of the best I have used. It is not chunky either. Has the consistency of milk.
