So having not had any time or money to spend on the boat as I've been trying to sort out a suitable towing vehicle, I've attempted various things & mostly learnt that
a) everything anywhere near a 300 tdi engine is even filthier than an outboard
b) I have some really helpful neighbours who have been brilliant at undoing stuck bits for me
c) i'm going to slap everyone who says 'I told you so'
The bastard thing decided to overheat in Swansea and has now been diagnosed with a blown head gasket. According to the internet its really easy to replace, according to the garage its several hours work and probably not worth doing.
Aaaarrrrrrgggghhhhhhhhh I want a foreign car !!!!
That is all. Thanks for listening.
