[QUOTE="Iceduke, post: 618029, member: 3721"] Anyway decided to go ahead with my DIY and here it is... You'll need the following tools: -10mm T bar wrench -10mm small wrench(for small hard to reach places like the Vacuum Pump) -8mm small wrench(for 1 darn screw that held the VP line in place) -Used rags First remove all covers and related head cover screws. [ATTACH=CONFIG]25420[/ATTACH] Remove the head cover [ATTACH=CONFIG]25421[/ATTACH] as you can see, my block is still sludge-free which was one of the main reasons I decided to get the car :) With only the cover off, you can only replace cylinder 1 and 4 spark plug tube o-rings, for 2 and 3 you'll need to remove the cam and the corresponding Valvetronic unit. As my 1 and 4 plugs are only wet so only changed those. Theres 1 big and 1 small ring so you wont get mixed up. To remove them just wiggle them out of place and voila :) [ATTACH=CONFIG]25422[/ATTACH][ATTACH=CONFIG]25423[/ATTACH] Was quite hesitant to tackle the vacuum pump o-rings but decided what the heck... lets go...it was real tough getting the 3 10mm bolts out but managed to, lucky em fingers arent erm homer size :P Vacuum pump removed... [ATTACH=CONFIG]25424[/ATTACH] further outer bolts need to be removed to replace the big O-ring, as you can see the old one is virtually flat hence no more seal... [ATTACH=CONFIG]25425[/ATTACH] Put on the new seal and apply some gasket sealant (bought from John of Bomin)... [ATTACH=CONFIG]25426[/ATTACH] Reattach the Vacuum pump, remember to align the notch to the exhaust camshaft, or else you wont have brakes... [ATTACH=CONFIG]25427[/ATTACH] Lastly, put everything back...time taken approx(including testing) 4.5hrs. Price RM 27 (for 4 tube o rings + 2 VP rings @ Suan Huat). Hope this will stop or at least slow down the oil consumption...so saved rm1.2k in new VP part and labor by DIY. hope this helps :) [/QUOTE]
