just read over this thread for the first time in a while and im not happy about how your going about this, i have never used the term "sight knocking" i told u exactly what happened with that engine. you were told it was knocking its tits off and i gave you it for £150, i had to pay that for a new head when i could have just used the 1 from that engine not to mention the brand new water pump brand new timing belt kit etc. I also had to borrow a van, get added onto the insurance then go a 3 hour drive there and back to pick the engine up for you and threw in a full set of wiring looms and bits and bobs for a little extra. dont make it out as if i lied to you mate as you where told everything that happened with the engine and everything i knew about it. how could i possibly have knowen the block was warped? asad i would love to see you try! why should i refund for an item that was sold as discribed?
