Clutch Advice

[Tempest111]

Good day

Wayne here and I would like some advice with my car's clutch, i have a Golf MK1 running a 2.0l 16V ABf with a FFZ gearbox.

When driving the car normal(slow) the car tends to drive beautifully, but when hammering the car and change gears from say 2nd to 3rd gear it is as if my clutch slips (revs climbing much faster than actual speed) then i let go of the throttle for a while until it hooks then i can step on it again, i have a brand new LUK clutch kit installed, worked fine for around 150km and now im back to square one.

The car is used daily for 120km a day.

Any assistance will be greatly appreciated

Thank you

Just to add i have removed my gearbox, clutch and flywheel, inspected the crank seal and everything is completely dry as i thought maybe its oil on the clutch.
