I had the Dax Gt40 in for its annual MOT last week and it came out with an advisory....... again.
they report a core,plug is leaking and it is the same one replaced by the garage a year ago at last MOT and that the one further back on the block on the same side has started weeping.
The core plugs are for the coolant system. The big leak one has been replaced about 5 years back too so the same one has gone twice!
Engine is the Rover/Morgan aluminium block.
So question to the engine gurus,
Do you suggest sealant when installing these plugs?
If so which sealant?
Do the holes need to be reamed out or similar? Or the bore “roughed” with sandpaper to help sealing?
or should I be sending it away to get screw in plugs fitted?
And can anyone suggest why this keeps happening?
thanks in advance
