freelander k series replacement engine

:blabla: hello everyone,ive got a 1.8 petrol k series. its done 118000 miles on one head gasket and gets looked after very well. just started to get high emissions and has developed a small engine oil leak, also a compression test read :- no 1 - 160, no 2 - 120, no 3 - 150 and no 4 - 180 is all this related ? the engine appears to running ok with no signs of hgf and i was thinking fix the oil leak slap on a new head gasket just to be safe and see what happens. the other thing to do would be to replace the engine but with what ? the rest of car is solid.
any suggestions pls ?:monitor_punch:

Does it use a lot of oil? if not then try another compression test but this time put a spoonful of oil in each spark plug bore first and see if the readings rise substantially - this would indicate worn bores or damaged piston ring. if compression does not rise much then its likely to be a worn valve oil seal or HGF maybe - perhaps a slight compression leak past the fire ring on the gasket into an oil way putting extra crankcase pressure and causing a seal to fail.

High emissions could also be a faulty CO2 sensor or cat. A well looked after K can do high miles, the VVC unit in my old MGF had done 116k and was still sweet with low fuel consumption.

you mean worn valve seats not worn valve seals
