1996 VW Jetta 1.8

[ncs1]

My son has a 1996 VW Jetta and his low oil pressure and buzzer started going off. We changed the oil and it seemed alittle better but still came on. I'm reading here about the 'big end bearing' and am not sure what that is. Is it the main bearing on the crank ? We intend to flush the engine and change the oil again, probably pull the pan to check the pump.
If it is the big end bearing, does the engine need to be out of the car for this repair ?
thanks,

No i think you are able do that with just the oil pan off. But it would help if the car was above you.

thanks for the info. But still not sure what the 'big end bearing' is. Is it the crank bearings and if so, doesn't the crank need to be removed.

The big end bearings are the ones that go between the crank and the con rods, the crank should not have to come out, but I have only every done this job on my MGB which is about 37 years old.
