Any tips on fixing the oil leakage I have?
It's not huge but I worry it will get worse.
My xjr is a 2000 model with 130,000 km on it.

Small droplets appears all over the my garage floor.

 

A fairly common leak is from the oil gallery plug above the rear crank seal, or from both. This leak would be blown all over the undercarriage as you drive. Inspect the area at the connection of the gearbox to the engine, the bottom openings at the bell housing. If they are very oily, then the leak is from the areas I mentioned.

 

Thank you very much.
I will try to figure out where those places are.
Do I have to lift the car for inspecting those?

 

You can just jack-up one side at the front sufficiently so that you can crawl under. A torchlight will help.
