I have a 1998 land rover discovery 1 LSE. It just doesn’t want to idle. It has a big oil leak with white smoke coming out the back. Im thinking its either a Blown head gasket or bad piston rings. I have so far replaced the fuel pump, fuel filter, oil, oil filter, air filter. Cleaned the Idle control valve sensor along with the air valve. It still wants to idle bad or not run at all. It does great when you bring it to high rpms (2000 +RPM) any ideas on what it could be or what I should do next?

What to do next?

STOP.

looks like you have a GEMS engine, it is very similar to the older Lucas hotwire system, on that basis I would:

1: do wet and dry compression test.
2: check for inlet leaks.
3: check/set throttle pot base voltage.
4: The ignition is, I believe ecu controlled so you can't really check the ignition timing but just bear in mind crank position sensor.
5: Check the o2 sensors are working.

If you have the right equipment, a leak down test might be useful as would checking vacuum.

You dont mention if you have any issue with coolant level?
The oil leak area needs cleaning up and running to try and identify if its the valley gasket or head gasket from the look of your pic.

What do the plugs look like?
Do you have any diagnostics for some live data?

And all above ^^^

Oh and welcome :).
