Spark plug sleeves

My 4K motor is leaking oil from the spark plug sleeves  I am guessing they need replacing. Are these sleeves readily available from a Toyota Spare Parts dept or do you think I will have to replace the rubber o-ring and retain the original sleeve body? Any ideas on costing for new ones?

is it leaking from around the top or around the bottom.
if the bottom is damaged form doing up the plugs too tight (or just repeatedly), you can buy them new from toyota as parts for a 7KE motor (they are the same).
for the rubber, i prefer to use appropriately sized O-rings with a very slight smear of silicon. seals much better.
check that you have not blocked off the rocker cover vents (and PCV) as high crankcase pressure often results in oil being blown out the spark plug tube seals...
if it's just weeping out, try using o-rings...

thanks stewart,
the body itself isnt damaged in any way, so I may just replace the o-rings and take your advice and put a touch of silicone to seal. Its actually leaking out the the top of the sleeve, so I think just the rubber ring needs replacing
