How about installing a real oil pressure gauge to monitor whats happening? We did that at the first shop, that's how I know it's "barely sufficient". The low oil pressure is established, what's causing it has not been conclusively determined, although I think the consensus opinion I've ac...

I think getting a good xW-40 oil in there may help prolong your motor until you are ready to move to another car. Its probably not worth the time and money to investigate things any deeper. Yeah, judging by everything I read in this thread, it may be time to throw in the towel. If the engine has to...

Oil pump failures are very, very rarely the cause of low oil pressure. The biggest cause, short of obvious things like leaks, wrong viscosity oil or clogged pickup tube is in fact excessively worn main and or rod bearings. You could try a higher viscosity oil, it would mask the problem but still be...

I've been going about 50,000 miles on the same gearbox oil (last changed at 160k) so I'm coming up on another change. I hear a lot that if I change the ATF fluid now, it will start acting up due to the age of the unit and the "friction material" draining with the old fluid. Is that true? F...

I recently graduated from college and am starting my first job. Current vehicle is a 2001 S80 handed down from my parents. It's at 210,000 miles however I don't know how long it has left in it because of engine oil problems (separate thread). So if I can't really figure it out, I'd like to stick wit...

At idle (below 700 RPM), the oil light will come on and "No Oil Pressure, Stop Safely ASAP" or "No Oil Pressure, Stop Engine" will appear in the DIM. When RPM goes above 700 RPM, the light goes out. Had two garages look at the problem. A third party shop (specialist in Volvos) cl...

I own a 2001 S-80 that has had erratic idling for years (I can remember as early as 2005). It appears as if the problem is worsening in recent weeks. When idling, I'll notice the tachometer dip below 0.75 RPMs and the lights on the instrument cluster dimming. The engine appears to compensate by send...
