My MK3 Golf hasn't been as reliable lately as I thought it would be. The last couple of weekends at the track I had a mechanical problem on Saturday.

First weekend was a intermediate shaft seal that leaked, oil got to the clutch and it started slipping.

The second weekend, the master cylinder failed.

What items should I replace to reduce the chance of not finishing the weekend? I made the car safe, and I thought it was reliable. I was getting ready to make it fast, but I have to go back to the making it reliable step.

Maintenance that has bee done to it in the last eight months:

- Shifter rebuilt
- new tie rods and ends, ball joints
- new control arm bushings
- new valve cover gasket
- new front pads, rotors and brake flush with Motul RBF600
- new timing belt and tensioner
- replaced front and rear crank seal, intermediate shaft seal
- new clutch disc, pressure plate and lightweight flywheel
- new clutch cable with manual adjustment
- oil filter and oil changes, new gas filter, new air filter
- new spark plugs and wires
- new PCV valve and installed catch can
- coolant flush, new expanasion tank and hose flange piece (next to head)
- tranny fluid changed
- new engine and tranny mounts
- vacuum lines replaced and A/C vacuum lines deleted
- EGR deleted
- TB cleaned
- new TT cat back and deleted cat

Thanks, Edison
