Wanted p38 3950cc engine

Hi all
just bought a westminster late 2001 range rover 3950cc on lpg
looking for a replacement engine or a company that will take my engine out, overhaul it and refit it.
It has overheating issues.
Any assistance will be greatly appreciated.
Kind regards
Chris

I'd recommend a clue to where you are uk north south east west?

I am In Lincolnshire
Thanks
Chris

I'd suggest you post your issues with it could be water pump /radiator/ head gasket/slipped liner or faulty vaporizer. after that you can decide what to do and someone may be able to suggest somewhere local to you

Hi
It will drive for four or five miles and thermostat kicks in.
AA suspect head gasket, but there is no water in the oil.
Need to use it to trail my campervans up and down the country, so maybe thought the best option was to re-condition or swap the engine.
Any names of decent companies that could help me out would be great.
I am not clever enough to sort it out myself!
