hi hope someone can give me a little advice. i've got a defender 110 csw 3.5 v8. wanting to change engine to a 300 tdi. just wanting to know if it's straight forward to change log book to diesel with dvla. and how you go about with insurance company. it's insured now as a 3.5 v8. do you cancel that policy and renew with someone else?. just like to get it all sorted in my mind lol. if someones done this lately.would be great to hear how it went. many thanks in advance. dave.
