Oil level reading

Post by mechanic80 » Tue Aug 13, 2019 6:16 am

Recently purchased 2005 NA Baja with rebuilt engine, new w/p, timing belt etc, etc... When I first checked the oil dipstick it read WAY too much oil. I immediately drained the oil but got the correct amount of oil (about 4.25 qt,) replaced the oil and of course still read WAY too much oil. Could see repairs made to the tube on closer inspection. Wrong tube? Wrong dipstick?

The dipstick has a notch above the upper level.
Just after driving or while the engine is warm, the engine
oil level reading may be in a range between the
upper level and the notch mark. This is caused by thermal
expansion of the engine oil.

If you'd like, I can measure my tube and dipstick lengths. I have a 2003 NA (I'd think they'd be the same as the 2005 NA, but not 100% sure).

By "overfill" I mean theat the level reads past the first twist, past the second twist and a half inch above that! It seems to read about 3-4 quarts over and yet it's not. I understand there is a 20006 STI oil pan that's different. If that were installed, might that account for the readings? I think I'm gonna stop by the local boneyard and see if I can find the exact same engine and go from there.

Where are you? Having another Baja to swap dipsticks with would be a good test.

I'm in Albuquerque and there are no Bajas in any junk yard but there are plenty of subarus.

It's the same dipstick as the same year legacy
1992 Legacy SS, 5mt and heavily modified
2000 Impreza RS Coupe, RSTI swap in progress
2003 Baja, 4eat & NA. Bone stock and loving it!

Just to be sure we're on the same page (is the device plugged in and the power switch turned on...) because I don't know you or your car knowledge.

Remember to let the oil settle a few minutes before checking it.
Pull the dipstick
clean it
insert the dipstick
read it

When you have drained and filled the oil, start the engine to fill the oil filter and passages that may have drained then let the car sit a minute or two.
