Ok for some reason my Oil Light is flashing some at idle.
Anyone has any idea why the hell is this happening?

The only change I did was change head gasket and add ARP
I regularly use 20w50 oil but when I changed the gasket I added 10w30 (Mobil 1 stock) until this next weekend. Race weekend = new fluids for my car and new oil change with 20w50.

So, maybe I burned my oil this past friday after 6 drag passes on 10w30? Or something went wrong when my head gasket was removed? Its only at idle and its not constant, its really weird.

Thanks for any info

 

 

Oil was ok and clear, a suggestion of a friend is that with the turbo (50 trim) and with the heat here and 3 consecutive passes that I might have burned down the oil. Dunno, I just did one heck of a pass to 120 mph at the street with the car and @ idle it flashed like 2 times only, I stopped the car, let it cool down in idle and no more flashing. I think yes its probably the oil, the oil pump if its failing its supposed to make the lifters sounds like hell because they get no oil.

Dunno, more input is well appreciated.

 

Check the oil sending unit switch wire might be loose.

 

Any idea where that might be?
Thanks

 

Just to throw this out there, but i am sure you would know this if this was the problem. If the heastuds are not torqued to spec and properly you can leak alot of oil from where the block meets the head. You may want to look around your block for any leaks.

 

Its down near the oil filter housing...

 

Oh no...its under the intake on the back of the block.. a ***** to get at. Mine was leaking once.

 

Mines doing the same. It comes and goes. Let me know if it that works. Not sure what it might be. I mean it runs smooth, no noise at all. Just once in a while when the oil gets hot with the oil temp gauge the light flickers on and then dissipates. Let me know what you try..Thanks.

 

Ok when I find a solution for this I will let you know.

Did you removed your head? Just a question because this started happening after changing head gasket & installing head bolts, no idea, sounds extremely weird but I will get to the bottom of this.

 

nope haven't messed with the head. it just started out of the blue.

 

EVO's run really low oil press at idle when warm specs say 5-7 psi at idle so check the grade of oil you use and see if the oil is due for changing because the older it is the thinner it gets and the lower the press.
I think the press switch is set to turn on at 4.5 psi

 

You just answered your own question.

 

i had my light go out... like the sensor didnt work :\

 

Sensor changed and problem fixed.

BTW light was flashing with 20w50 oil as well.
