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.
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...
