Omega General Help / Re: Omega X25XE Oil pressure light flickering at idle

« on: 30 June 2025, 05:16:52 »

Thanks for the help, cleaning the sump was the right call. The bottom of the pan had around 2 milimeter thick layer of jellyfied oil, but i think the issue was caused by the pickup being blocked partially by the jellyfied oil and the o ring for the pick was also extremly flat. Anyway the issue seems to be resolved.

Omega General Help / Omega X25XE Oil pressure light flickering at idle

« on: 24 June 2025, 05:52:46 »

Hi!
I recently started reviving a 1998 2.5 V6 omega with 170k kms as a project car.
After a lot of work i got the car up and running pretty nicely, however after my first longer drive in it i noticed that the oil light flickers at idle when the car is really hot.
It has new:
-oil (5W-40)
-oil filter (newer cartige style), oil press pressure sensor

What are the common couses of this? I doubt its excessive engine wear as it sound really nice, however i do know that is was neglected for about 4 ish years before being parked in 2012.
I have read that the relief valve could get stuck but where do i find that?
