oil change - wet sump
Discussion
Hi Guys,
need to drop out the mineral oil from the prosport to replace with 'normal'oil.... i have one of those sealey oil extractors... is it best to go in through the dipstick hole ? or oil filler ?
given this is to replace the mineral oil - do i need to do something different to get the oil out of the oil cooler etc too ??? assuming i really need to get all of that oil out....
Mark.

Neither really! Via the oil filler you will just hit the clutch or the inside of the cover without getting down to the sump. The oil dipstick will get you down to the bottom from memory but much better bet to just get it up to operating temperature then remove the sump plug. Then trace the bottom hose from the oil cooler to where it connects to the side of the oil filter area & disconnect it to allow the oil cooler to empty out too.
conversely you could try to turn the car upside down and shake it all out 
The sump plug is there for a reason... I know it's a pain to take off the Diffuser... all six bolts however it's also easier to change the filter and a good time to get underneath and take a look around to make sure everything is as it should be
Perhaps you could look at it this way. It's a race car, it needs to be looked after and loved, and it's yours. A lot of people would give their right arm for one so stop trying to find short cuts and get on with it.

+1 Some garages do it that 'suck it out from the top' jobbie, but no way would I ever let that be done to any car of mine; not even a road car and no way a race car. Metal is heavier than oil and it sinks to the bottom and lies in that nice flat sump; a nice gush of hot oil out through the sump plug will help take a lot of it away; in fact, in them olden days, I seem to remember sump plugs with a magnetised end that looked like little metal hedgehogs when you took them out; proved to me just how much contact metal gets produced by a healthy engine during the course of it doing it's business; best got rid off rather than being re-circulated like abrasive grit. Get yourself a beam put across the walls in the garage, then hang a beam clamp & 1/2t chainblock off it with a 1mtr sling wrapped round the roll bar, winch the car up two foot off the floor, sticking a small trestle under the front diffuser. You will then find removing the rear tray / changing the oil / general under car maintenance is a relative joy!
Gotta agree with the comments above, sump plug all the way. Diffuser is a 10 min job to take off. Tip don't worry about running over the edge of it with the rear wheels. Jack the car up with a proper trolley jack on the rear jacking point. When you've removed the plug lower the jack back down so the rear of the car is level again to ensure you get all the oil out. Regarding the filter invest in a proper bike filter socket, to tighten it do it up hand tight then add another 180degrees with the filter socket. Sorry if I am teaching you to suck eggs here 
cheers guys :-) i managed to 'suck' 4.1L out of it last night.. but will attempt the diffuser removal this evening - it looked like it was rivitted onto the floor section when i had it up initially hence looked for another solution.
I also saw the guys in the radical workshops with these sucking the oil out - but maybe that was just to empty the dry sump tanks.. not sure
Rob - yes agree, proper filter holder definately handy - had one last year for the honda.. will definately invest in one for this baby too..
I think i've just been spoilt at the ease of working on the striker last yr..

The diffuser is held on by the two bolts that also hold the rear subframe, there will be two loops halfway along and these allow it to be cable tied to the chassis. And finally, may not be on your though, there will be a bolt in each side pod that holds up the corners of the diffuser.
Have fun

100% correct Rob.. only took 4 bolts - and the two brackets cable tied to the chassis members..
definately better to drop through sump - when i bought this - it looked like the difuser was rivitted in along the back of the bulkhead - obviously this was just the back of the floor tray where the difuser locates over.
would have been a nightmare getting the oil filter & oil cooler hoses off without the difuser off anyway... interestingly the oil filter had a jubilee clip - but wasn't lock wired !!
good to check the gear change bracket bolts etc too - will be part of normal maintenance between races now....
Must say the sump, and oil take off's are very tidy - fair play to powertec for the work... also nice to see the loom ends to oil light and oil pressure all labelled up etc.. makes it all easy for numpties like me :-)
Thanks again to simon, Rob and the other comments..... am hopefully getting closer to being ready for testing...

ah ha !! didn;t study that bit !! too many years playing on bikes made me want to lockwire as a natural course i guess !!
the work on the sump and billet style oil unions etc is lovely i must say..
hopefully the bits of skin i donated to the radical will come back soon enough - after fitting a new battery !! damn its tight in there...
oending a few minor things and the weather we may be ready to test later this week :-)
