just bought mk3 GTI 111000 miles no MOT
got gatage to put new timing belt on it --- when they did it they found the " tensioner " had seased up
anyway they sorted that out and she was running well --- but when doing MOT and reving her for the omissions test she just stopped --- no bangs or loud noises
now they tell me there is no compression on any cylinders !
they say things are still moving inside
I had put K seal in her anyway so the head gasket should not be the problem and any way this would not effect ALL cylinders
to me there must be an open valve in each cylinder
have asked them to take the haed off and see what they find
I need so ideas from you brain boxes out there ---- what can it be

?
confused Rob of Ganthill
cheers
