Did you change the oil and then start getting high oil pressure or did it just start happening?
I got the engine out of a wrecked ski from a place in Florida, I assembled it with a oil pump assembly and housing from one that was sank and the engine locked up. After running it, it blew a new turbo and snapped the impeller shaft. I took oil pressure readings a bit to late, they wouldn’t warranty the turbo for logical reasons, I removed the engine and replaced the relief valve, installed a whole new oil pump assembly, blew out all the passages in the housing, installed new internal screens. Removed the oil sump and completely cleaned the debris out. Installed it and cold at idle for two minutes I have 80 psi. It is driving me nuts. Also new Honda oil filter and new oilthe high oil pressure alarm should activate when pressure falls below 31psi and the low activates below 3psi
I do not have any oil pressure alarmsthe high oil pressure alarm should activate when pressure falls below 31psi and the low activates below 3psi
