Did my Freebie 2001 last May - 68581 on mileometer . Mine also had been done before with the MLS gasket and the head had been skimmed, could see the circular "skim" marks!!! Took to Jse Services, Blackwood, Gwent Tel 01443 835898 for advice, recommended PRESSURE TEST (most important as it turned out), reskim, valve seats recut and new vavlves & springs etc. Approx cost just over £200 not bad. After pressure test "Failed" head cracked between exhaust 2 & 3 only possibility to get engine going was to purchase new / reconditioned head. OH Bother I thought!! until after a phone call to his suppliers he got me a fully reconditioned head for £270 inc VAT. He even let me off the £35 for pressure test!. New head arrived NEXT DAY went to collect and picked up new gasket set, water pump, head bolts, timing belts, "gasket cement" for shim layer of gaket etc came to £398 inc vat. Did not replace oil rail on rebuild as deemed not necessary by JSE but did fit the modified cooling kit part no PCH001190 approx £60 from Land Rover Swansea. Rebuilt engine with son making sure of correct torque settings and timing etc. Changed plugs and did oil / filter change from "clotted cream" to recommended genuine oil. Engine fired up first time after rebuild. Bled the cooling system approx 3 or 4 times after running for approx 50 miles and checked daily for first month thereafter "to be Sure no coolant loss" Since then and 7500 miles later NO problems, getting 29.8 mpg (checked every time I fill since rebuild) which includes approx 500 miles towing my boat around to various places to fish and general town / motorway driving. I would add that I do not have any affiliation to JSE SERVICES except that I am now a loyal customer and respect his opinions and views. I hope all goes well with your rebuild LOL.
