oil pressure a bit high

[tuxman]

been out in the can-am today ,warmed it up well before i went out and while on my run i noticed that my oil pressure was a bit higher than normal , it reads about 4.5 bar ish when hot normaly but today read 5 bar+ when i reved it over 4000 ,just wondered if anyone had noticed the same , engine builder recons its the cold air cooling oil more than in the summer ??? not sure . simon

sounds daft I know, but were the lights on this time? I have noticed all my gauges read a bit higher with my lights on! Must be a bad earth, so need to sort it.

no lights were off did put lights on and made no difference ,got me a bit confused never thought i would worry about too much oil pressure !!!!

Have you got a dry sump? I can't remember.
On my pump, you can just wind out a screw and adjust the running pressure.

no wet sump with a high pressure pump

Hello Simon, I don't have a wet sump so can not speak from personal experience but I would not think that the cold weather would make an awful lot of difference once the engine is up to operating temperature as this will be static despite the climate outside of the motor. Could be the relief spring in the pump has maybe work hardened a little or the plunger/piston engorged a little possibly, or a combination? A blockage in an oil way but I would have thought that unlikely. I would monitor the situation and if the pressure were to rise more than another 5 PSI then change the pump. If it does not solve the problem at least it can be eradicated from the list of suspects.

Hi Wayne , going to take it for a good run this weekened have checked everything out and it all looks normal ,was going to service it before the spring so will not worry about it to much at the moment first time i've run it over the winter so we are noticing a few things that are a bit odd !!!! no grip for starters

Be careful bud it's slippy out there...

If you have an oil cooler then the weather may make a differnce to running oil temp, some fit a valve that shuts off the cooler until a certain temperature.

Could it also be the grade of oil?

Hi Simon

Like Andy has said about the oilstat. If you don't have one the oil will be running cooler than in the summer and it may be effecting the oil viscosity giving you higher pressure.

Fixed it loose wire on the sender !!!! must have been loose for a while as the plastic nut had gone ....ha ha wire just hanging on ...sorry must pay more attension to her ,enjoyed the run out in the sun but holy crap the roads are sh1t going to keep her safe until spring i think, scared me abit !!!!!

[GTWayne]

Simon, sort your shit out for Christ's sake! Even I could have and would have spotted and fixed that before posting and causing a media frenzie

I agree with Wayne oil pressure issues are not to be taken lightly and I now feel completely traumatised. I shall have to go an have a drink even though it's not Christmas yet.

Shame on you.

Steve

sorry guys i will hang my head in shame ...........i will force red wine and cool beer down my neck so i have a terrible hangover in the morning !!!!

No need to torture yourself Simon, but since the demise of Luckyp's motor, I think we may all be a little over sensitive in that area.
