Replaced water pump then had oring's where tubes go to back of block start leaking...so removed intake replaced gaskets PCV plate etc etc and started her up.....took for hard test drive (Wife would take to work in morning) and she ran great..better than ever. In the morning....5 hours later!! Clutch wouldn't engage.....like clutch slave or master is bad.....can't see how changing intake gaskets had anything to do with it....coincidence???? Any thoughts..

Thanks
