front discs and pads were an absolute joy to do. as was most other jobs. however when i pulled the coil pack of no1 spark plug it was full of rusty water. i blew all the gunge out with an airline and replaced the spark plug . anyone any ideas where the water come from. hoping its not head gasket related. another thing the old plugs were loose which i thought was weird. whats even weirder is the other week i did a service on the wifes c2 vts and the plugs were loose in that as well. is this the new thing with garages.
