stevie_b Posted October 11, 2006 Share Posted October 11, 2006 I've changed a headgasket on a Rover Metro. Not too bad, just familiarise yourself well with the procedure before starting. For example, you don't want to undo the head bolts in the wrong order. If you've got "mayonnaise" in the engine (from mixing oil and water) then when the HG's been changed, run the engine with diesel oil for about 1000 miles to clean it out, then do an oil change as normal. Get the head surface checked for flatness, and get it skimmed if it's warped. When you've bolted the engine back together, whilst the spark plugs are out turn the crankshaft manually using a spanner and make sure it turns relatively smoothly with no untoward resistance. If you've got the timing wrong, you'll hopefully feel the valves impacting the pistons. Better to do it this way, than to crank it using the starter motor and then need to replace all the valves!!
