can anyone pls tell me if it is necessery to have a pressure release valve in between the pump and engine. any info would be great thanks
I would not say necessary unless you have a system requireing it. A dump line is normally needed if you have a header system with a control valve.can anyone pls tell me if it is necessary to have a pressure release valve in between the pump and engine. any info would be great thanks
I ran mine for years without one and it was fine. When I bought the used boat I'm running now, it came with one (Watts bypass) in a box of parts and I figured what the hey and cut it in. It works fine, but like I said...........it always worked fine before that too.can anyone pls tell me if it is necessery to have a pressure release valve in between the pump and engine. any info would be great thanks
Im sorry i meant intake gasket not headI cant say if they are always required, but i can easily peg my 35 PSI guage on my dash when my regulator is not set correctly. I run a regulator and try to keep the water around 25PSI at WOT.
I dont know if this is causing your head gaskets to go, i would think other gaskets would go before those, but i'm no expert. My guess would be that if your blowing head gaskets it's probably cuz your surfaces are not straight... either the block deck or head surface. Again i'm no expert.
ah, well ya, could be! What intake gaskets you using? I was using felpro gaskets for a while, they seam like a real poor design. I switched over to the cometic gaskets on my new mill and they, to me, feel more solid and like they will stay in place and not slip out into the valley (problem i was having before).Im sorry i meant intake gasket not head
IMO that is your prob. you are adjusting your press after the motor, try it on the inlet, you then can control press. into the motor not restricking the out flow. With it on the out flow side of the motor any rise in press will be behind your valve that can cause gasket to fail. just my 02 cts.devili dont have a valve on the pump side just on the side that exits the engine

I've heard of this being done as well. However, on his setup there was no valve at all on the pump to restrict the inflow. With a valve on only the dump, that would for sure blow gaskets if it were closed down far enough.In the old days--- You put a gate valve on the intake and exhaust or dump side. You controlled engine temp by playing with the valve settings till you got a constant even temp. No body had a water pressure guage. I had trouble with leaking copper head gaskets and tried several rememdys. None worked. I installed a Pressure bypass not a pressure regulator and all my problems went away.
