I need help. I have a 2000 Skoda Fabia 1.4 mpi.

The problem is that I replaced the head gasket because of a leak.

But I'm still losing engine oil.

What is the solution, and is there a connection to the thermostat?

Skoda's 1.4 8v MPI engine doesn't have an oil connection to the thermostat housing.

Maybe your piston rings are very worn, and the car is burning oil (noticed any kind of smoke from the exhaust?)

If not that, I guess that your oil goes elsewhere, and you should be able to spot a leak.

Loosing oil or water?

Head gasket normally leaks water rather than oil

Try a compression test to see if all cylinders are fairly equal and within spec. If your losing a lot and theres no blue smoke then it must be going somewhere. If theres an undertray fitted I would remove and have a good look. Have had oil leaks in the past that ended up on undertray so no drips. Check theres no oil in coolant as well.

Could also be crank seal in bellhousing area. On my sons fabia theres a slight slot at base of bellhousing where it meets Gbox. I assume its to let any fluid that leaks out but are prone to blocking.

Hello, welcome to the forum.

How much oil is being used/lost?

Might be worth checking breather valve/PCV in case its clogged or jammed.
