oil temp climing
 

Can anyone tell me what to check , as to why my oil temp is going up to 230 when my port motor stays at 160 ? the motors are all rebuilt and all coolers cleaned and all oil hoses flushed, The motor temp is at 150.

Did you spin a bearing? I learned the hard way thinking I could clean a cooler:(

I don't thing so I only have 10 minutes on them at 2500rpm. I was told it could be the t-stat for the oil system located in that square block that the filter screws on to.???????????

I ment Did you spin a bearing on the original engine?

230 degrees for oil is about perfect. I would question the one at 160 degrees.

ALso at 160 I would check to make sure you do not have the oil lines reversed. I have seen that done, no oil flowing through the filter and the temp sensor was on the filter pad.

Where are the sensors for the oil temp located?

i had same problem. it was where the water intake comes thru the transom. ( bravo drives)
the fitting collapses.

What year are your engines and who plumbed the oiling system? Sounds like it could be the oil thermostat in the oil remote. Easy fix, just need the new t-stat, an o-ring.

150/160 is too cold. I like the 230 side better.

if the intake hose was collapsed the motor would be over heating also.

!big jim I got into a lot of seaweed and over heated the motor and stuck a piston, did not spin a bearing. the sensor for oil temp is on the block where a oil filter would screw on.

John changed the t-stat and o-ring problem gone. Another good job from a fellow boater.

Would that be part#9 ? The description says n/a !

does the factory oil filter adapter have this t-stat.i am having a high oil temp problem and never thought there was a stat for the oil.

The oil Tstat will not help with a high oil temp problem. Its job is to let the oil get to the correct operating temp faster. It by passes the cooler until the oil reaches temp, and then it allows flow through the cooler.

called my dealer on this t-stat and he had no idea what i was talking about.did they use oil t-stat on stock 454 mag?if the t-stat was stuck not allowing oil to the cooler this could create high temps right?

They were only used on blue motors.

If you DO have the system, yes if the Stat was stuck and oil was bypassing the cooler you would have VERY high temps.

I had the same problem... was the water inlet hose from the drive to the strainer. It was enough for the oil to get hot but not enough to get the coolant too far off.
