Hi
I have only just read the thread
While i feel for your lad
You say the header tank was mucky or some thing similar, why didnt your lad see this or any other issues.
If he isnt mechanically minded why didnt he take someone with him.
I appreciate this doesnt help now but im just curious.
If it was my lad,s car i would tell him to cut his losses and sell as is.
At least he will be 3k up and not looking at his ***** up every day of the week and making him feel like s*it.
I may seem harsh but i am also a straight talking kind of bloke, deal with the cr*p and move on its the only way.
Hope you sort something soon
Rich
