HI, DHADLEY. AFTER WORKING HARD ON THE ENGINE<br />(OMC V4, Looper, 1986)...., I WAS THINKING:<br />WHAT'S THE USE OF THE WATER PRESSURE VALVE LOCATED AT THE STARBOARD SIDE OF THE ENGINE?.<br />MAY I ABLE,TO REMOVE THE THAT WPV ??; OR I CAN PLUG THE HOSE AT THE BEGINNING OF THE THERMO. COVER ?<br />THANKS FOR YOUR HELP.<br /><br />DON

That's exactly what I would do. Use the cap and spring from a 93 V4 looper or newer. Then you can do away with the valve and all those hoses.

I've jusrt got the same motor and the pipe from the port T-stat was blocked off at the valve and routed to the pee hole. I restored it to original. If 'new style' T-stats were put in would this present a problem?
