Indeed old Opels are full of Torx screws and bolts, very irritating especially when the damn things are too tight to unscrew and strips,

had that issue with the aluminium sump bolt. I buy most of my tools at Builders, but you can also buy those from the motor spares shops, just take your time to buy everything, these can be expensive and always buy in a set. Also check second hand shops like Cash converters, you can pick yourself brand new tools at a steal.
yeh my nut or screw eventually stripped they said, they eventually got me a nice opel astra one which fits tighter and better... they also use a blob of this silver looking silicone.
anyways correct me if i am wrong, but it seems i have a torx type nut also for the sump which is the one i described about so not sure if this is an astra type or what.
anyways
So long as i can service my own car next time.
I did buy an entire service kit , i am just not sure how to fir the fuel filter it looks very awkward and the those clips looks like a pain.
also not sure if i need to keep those clips or if i can just use the whole set i get from the german looking filter i bought, forgot the name, its black in color, its not a Gud.
As for spark plugs and air filter and oil filter i am sure i can do that stuff.
I guess i just need a plastic tub or something like 10 liters for the oil to drain in to.
I just need to know what i can buy in terms of decent tools, i have a tool set but it is not great, its like a starter one with sockets and a rachet and stuff.
I need the torx stuff, i have screw drivers but size 5 to 10 and then i have another set from 10 to 20 i think but i need the hex set and or at least a decent socket torx set, game usually have nice stuff but i asm not sure what to buy and what not to buy,
My aim is to spend a bit here and there and make up.... dont know.i dont know if i can just spend 1or 2 grand and i dont really know what i am buying, and i am not a hardcore motor mechanic anyways
