    Riva Engine Cooling Kit Overheating

    Got out to test my new go-fast parts this weekend and everything ran well until it started overheating. I got the Riva Engine kit installed as per instructions but something is not right. The IC and Oil Cooler sprayers are moving alot of water but the upper exhaust manifold gets hot, the lower exhaust manifold feels cool (its fed via another cooling line). Is it possible to install the exhaust gasket backwards and restrict the water flow?

    Check if you put the Riva pump strainer in backwards. There is a hole on one side that needs to face the wear ring. This would explain why you're getting water to the IC/oil cooler & not the engine because they feed off the fitting on the strainer plate while the engine cooling uses the oem routing through the pump/wear ring/transom plate.

    Thanks, You guys are correct, I installed the strainer in backwards, I now understand why the stock one has holes on both sides.

    I checked the compression tonight, is 120psi normal?
