Hello Nick500
the I.S.C.V fell apart and got sucked into number 4, I have never removed the valve so feel a little pissed off.
A lesson for everybody, take yours out and put some thread-lock or better still, some super glue on the threads.
I could have just replaced the piston but decided to go for a full rebuild.
I still have lots of plans for the car, but as always costs so much.
Steve
