Dinky26 Posted February 19, 2014 Share Posted February 19, 2014 My EA81 on my Brat is fluctuating with its oil pressure. Goes down to almost nothing at times, then goes back up to about 3/4 on the gauge don't remember what # correlates with that. Yes there is adequate oil in the crank case too. Is this a tell tail sign of a failing oil pump? Link to comment Share on other sites More sharing options...
987687 Posted February 19, 2014 Share Posted February 19, 2014 Is that with a real oil gauge, or the stock subaru one? If it's the stock one, it's not really useful for much. Some of them read consistently, some don't... Sounds like yours doesn't. My GL probably has a short somewhere and my oil pressure depends on the humidity... lol Link to comment Share on other sites More sharing options...
Dinky26 Posted February 19, 2014 Author Share Posted February 19, 2014 It is the stock one. Didn't do this before I changed the white plastic piece that holds the gauges. wasn't working at all prior, cause I think I fried something in the original one Link to comment Share on other sites More sharing options...
ivans imports Posted February 19, 2014 Share Posted February 19, 2014 Is fairly normal to be low at idle as long as it comes up when reved if worried put a manual gauge on it to check exact psi Link to comment Share on other sites More sharing options...
