Hi guys, my old TJ 97 has been in my local garage for 3 months after what seemed like a radiator issue. The garage is now saying one of the core plugs in the cylinder head is shot (and can't be re-bored), so I need to replace the cylinder head. I'm not happy it's taken 3 months for them to diagnose the problem, so can anyone recommend a Jeep specialist in Essex or Hertfordshire (preferably near Waltham Abbey/Harlow). I'm looking to sell my TJ - which has been so much fun for the last 10 years - and just need to figure out cost implications......do I repalce the cylinder head then sell, or just sell it as-is to a Jeep fan who is handy with a spanner?
