Hi all

Just a note to say thanks to you all for your help with my 97' Astra..

Following my previous posts it has now been confirmed that the cause of my fault was a Chipped Exhaust Valve, which has put a nik into the top of the piston but should be ok, and luckily the bore was fine...

Indeed the cylinder head gasket needed changing, as did the thermostat, but the real problem was the valve...

The EGR valve was fine...

So I thought I had better reply with this just to throw a spanner in the works...SORRY.

Thanks again
MUSTANG
