Hello all,
I tried to change the plugs on my st 170 2002 reg but plug 1 &2 is jammed tight in and there is oil about half way up each of these plugs!!
I did manage to change 3 & 4 and no oil in these advice please.
Hi ive just had the same issue i soaked up the oil with kitchen roll(clean oil must of spilt it topping up)then used mole grips to give
more leaverage on the plug spanner careful tho worked for me.

Try soaking the rusted in plugs with penetrating oil (such as WD40) after soaking out the oil with kitchen roll.

Go very carefilly when trying to get out the plugs. You do not want to snap them off!
Thanks for your replys any chance it could be the rocker gasket that needs changing to stop the oil loss ?

WD40 is NOT a penetrating oil - it's a [url=""]Water Displacement spray[/url] - hence the "WD".
Sure it's not rusty water i had this problem and i thought it was oil turned out to be dirty water was getting through my washer jets and on to the plugs little seal up with sealent around the washer jets from under the bonnet sorted the mess.
no its defo oil I had this on my celica gt4 it was the rear rocker gasket seal on that one
if its oil then it does sounds very much like the rocker cover gasket.

The best penetrating fluid i can recommend is plus gas -

Absolutely brilliant stuff
