correct oil pressure

[jmaconaochy]

I have a 92 loyale wagon with 111K miles on it and it is now started the TOD.  I normally use 10W-40 oil and wondered what the correct oil pressure should be with the engine cold and when warm at 2000 RPM and idel?  If it turns out that the oil pump has failed does anyone know where a replacement might be found?

 

Thanks

Cold oil pressure is completely dependent on oil temperature, and as such really isn't a useful metric when comparing to someone else's pressure.

 

The oil pressure gauge on the dash is garbage, not accurate at all. They're OK for a relative reading, ie. it used to read 45 but now it only reads 35, but useless to compare against a different car. You'd need to hook up a good pressure gauge.

 

Oil pumps on the ea82 almost never fail, you may have a leaky oil o-ring (cam towers, etc), or tired lifters. There's a lot of good information on it if you search.
