Thanks for the sympathy lads.
I actually got the car back up and running saturday afternoon.
I'm still going to strip the engine down as i don't know what the problem is.
Could simply be the head gasket
After a long think over the weekend i think i'm going to keep the ZVH engine, sort out the problems and get the car on the road.
I think i will have to take the pistons out and send them away for checking to make sure they are suitable, and send the T34 away for checking just encase that is whats burning all the oil.
