Oil Pressure Worries

Hi all,

I am a little concerned about the old pressure in my gem and hoping that its not a tired engine begging to break down and get rebuilt.

Its a g180w dohc and lately i have noticed a slight all round oil pressure drop. It used to hover just between 2 and 4 kg/cm but now hovers right around the 2 mark

the guage goes up to around 8 so i am guessing this is rather low on the scale of things.

Is this becuase of lack of oil? i got the thing serviced and im not actually sure if this engine uses more than a stock gemini cause of the bigger head and 2 cams, there is a chance the workshop who did it may have looked up gemini and just chucked how ever many litres a stock gemini uses.

Any suggestions??

thanks!

How much oil is in the engine and how thick the oil is can be factors in oil pressure. My sohc is usually just over 5kg/cm (gauge goes up to 6), would have thought the dohc would run about the same oil pressure if not higher. Checked your dipstick?

well yeah my guage now goes off the clock over 6kg/cm or 80 psi and its a stock oil pump but yeah have you checked your oil?
if its full it might be the sender and if that fails its a new oil pump then

Its definatly not low. I'll change the oil tomororw, i got told it takes just under 5 litres, that would be about right yeah? i'd say itd take more than a sohc cause of the extra cam etc...

thanks guys
