Thanks to assasin1000 for this thread i can give you guys an idea on what to expect in AUD
the bluepoint tool GA317 costs ~$70
valve stem seals to me were $40 (ACL list them as the same as 3sfe)
the do hickey to hold the valves up was $30 odd
Labour was 2.5hours which thru me at work would be about $220
If you know what you're doing id say go for it otherwise it may be the most expensive oil leak you will ever fix.
Biggo wonders if the tool will work on 20v heads?
