Don't you just hate it when you cure one problem just to create another?
Decided to do the tappets on my Capri. Being a 2.8i it involves removing some of the coolant hoses to get the OS rocker cover off. Anyways, gets the tappets sorted, cures a rocker gasket oil leak at the same time. Decided as it was nearly winter and I had drained some water that now would be a good time to back flush the heater matrix and the rad. So, 20 years of rust, radweld and god knows what flushed out and all was well....
...until I got home and found steam coming from under the bonnet. Need a new radiator now. Bugger. Still, at least the heater works better than it ever has.
