Fixed the issue, thanks!
It was the oil pressure sensor. Replaced the old and I’m running normal pressure with no alarms.
Also found the issue with the speedometer, the tube had disconnected in one place and it’s working perfectly.
Appreciate all of the input!!
Update:
Changed the oil and filter with Volvo parts. I couldn’t believe it, I removed 5 3/4 liters of oil! Manual specs at 4.5 quarts so I was shocked at this! Ran the motor in the lake and it’s repeating the same intermittent low oil pressure. Next step is to hook up the manual pressure gauge...
Okay, I will start with the oil change and pressure test.
Every time the alarm sounds, it has been at a highe RPM. If I turn the key off and restart it will sit at idle showing about 30 on the gauge. I let it idle for nearly 30 minutes in the water without alarm or fluctuations and then it...
Wow, okay! Thanks for the advice! I’ll be doing the oil change this weekend and will measure the old. If it had too much oil, would that cause the drop in pressure? Also, is the alarm triggered by the gauge or the pressure sensor?
On the gauges. This is a Regal 2000 ESX with Faria gauges. The...
Gotcha! Thanks. Just ordered the oil change pump. Do you recommend any particular oil type. The Volvo Oil label says it’s a blended product. I really like Liqui Moly products ( I use them in my other German vehicles) but I realize the 4.3 is a GM block. I have a VP oil filter and I’m changing...
Thanks for the help!
I believe that number is A765107
Is there a link for running the pressure test somewhere? I’m also going to order the service manual from VP today.
I’ll start with the oil change as well.
Appreciate all the help!
So am I reading this correctly, my issue with the oil pressure dropping and alarm sounding is somehow connected to servicing the water pump and changing the oil? I’m just confused.
Can someone tell me where the oil pressure sensor is located?
I’m just going off the facts as I have them reported to me. I just purchased the boat. I was at the dealer last weekend and they told me every 100 hours or every season for oil changes. It’s running full synthetic. And impeller is every other season according to them (or 200 hours).
My...
I just purchased the boat and it has only had one oil change (after broken in). It has 57 hours on it. The oil still looks brand new. Should I change just the filter or do both?
That’s where my head was as well. It’s drops nearly to zero and then the alarm starts. Temp has been rock solid, running normal. You can see the oil needle drop, then the alarm.
I pulled the boat from PA to MO when I bought it. I’m thinking something got vibrated loose.
I have a 2018 Regal 2000 with a VP 4.3 L. Only 57 hours on boat. Had been sitting for the last few years. At idle speed all gauges look normal. Temp is around 170 and oil pressure is around 30 on the gauge. When I accelerate, the oil pressure gauge drops below 20 and triggers alarm. I’d you turn...
