Spark Plug Change

[cpaan]

tried to change the plugs on my st 170 today plug 1 &2 are stuck solid and the hole has oil in it at least half way up the plugsd

thats in both 1 and 2 . I managed to change 3 and 4 no oil in there .

Advice please

could be a leaking rocker cover gasket causing the oil seapage?...remove the excess oil from around the plugs and soak them over night in penetrating oil.....something like this.http://www.halfords.com/webapp/wcs/stores/servlet/product_storeId_10001_catalogId_10151_productId_274625_langId_-1_categoryId_165594

go easy on undoing them...use plenty of wd40 or the equivalent

investigate the cause of the leak,could be as simple as a new gasket...
