how tight?

[boaterntexas]

checking for shorts in my oile pressure guage lines, I found none, so I decided to pull the sender unit. when I took it off seen no defects, but I did hear a constant bubbling sound comming from inside the block, is this normal. I'm sure it is. considering I had just had the engine runnign for a while.<br /><br /> More importantly when I removed the sensor, I notice that it was not on all that tight, so how tight should I put it back on, should I screw it all the way in?<br /><br /> Thanks,<br /><br /> Thomas

Re: how tight?

First, check all connections to the guage and make sure they are clean and tight. You could easily have a loose wire on one of the terminals. That would cause jumping.<br /><br />Next, test the gauage:<br /><br />1) Remove the sender wire from the guage<br />2) Turn on power<br />3) Oil Pressure guage should read 0<br /><br />1) Turn off power<br />2) Connect sender terminal to Ground (G or Gnd) terminal<br />3) Turn power on<br />4) Guage should read full<br /><br />If above test work guage is ok<br /><br />Next, test the wire from the sender to the guage:<br /><br />1) Next, disconnect sender from gauge<br />2) Take a run of wire and temporarliy connect sender to guage termial <br />3) Start boat<br /><br />If all these test show ok I would hook a mechanical pressure guage up to the engine and rule out a bad or flaky oil pump or other engine problem<br /><br />Last resort I would replace sender, wire from sender to guage and check all other gauage connections carefully. Last I'd also replace the guage.<br /><br />Just my .02

Some where between Rare,+ Never.....<br /><br />If the Gauge Tests Alright by Grounding it....<br />Change the Sender... They Do go Bad... There is No "Looking Bad"....
