hi i am after a reconded head and full gasket set for a astra mk4 1.7 tdi eco 2001 i think i need a head and full gasket set but cant find anywhere that sell them,as my astra keeps over heating and the water bubbles and i have to release the presure as all the pipes swell ,only brought the car 2 days ago and the bloke said its had a head and gasket set 5000miles ago so it doesnt need that but had mercanic out and he said it does need either a new head or valves ,any info would be much appreciated thanks phill
