this might have been queried before but i couldnt find a definitive answer...
i've undertaken a service on the car today (2.2 astra) and i've struggled a bit with the oil filter housing. it's in a really awkward place and difficult to get a ratchet or spanner on it to tighten it to the required 25Nm. anyway, i've hamfisted the thing as tight as i can but when the motor is running its seeping oil from the seal. this might suggest that i havent tightened it enough, but i cant get a torque wrench on it. how do you lot manage, is there a tried and tested way, it seems to be in the most stupid position with no clear access (even with battery removed). thanks.
