Have had this car for 6 months and always had issues with oil loss, but until recently it has not smoked a lot and no signs of external leaks. Have just removed cylinder head and replaced burnt out / damaged exhaust valve. Now compression is back to around 13 to 14 bar on all cylinders. Replaced valve stem seals, lapped in other valves. Also done pressure test on cooling system which held up fine.but since refitting head,exhaust is very smoky, plugs are oily and oil on top of pistons, of course. Apart from oil issue, starts and runs well. I suspect a problem with crankcase compression , a blocked breather or hose but from what I can find all looks ok. Anybody got any suggestions or had similar problem ? Plan to test further for c c comp tomorrow , thanks steve

Did you replace all the all the valve oil seals,oil in the bores can come two ways either from the head downwards or upwards via worn rings or bores.
