I have just purchased the injector loom and timing cover gasket. They should be here tomorrow, in time for me to get my hands dirty over Xmas! :D
I ended up going with discolaw's suggestion (thanks!) to get the pre-sealed injector loom from MR automotive in Brisbane. I figured the extra $$ (only about $30) would be worthwhile it if lasts a few years extra.
I spoke to Dwayne at MR and he said that they don't guarantee it will be permanent, but haven't had to replace one they have done yet. Good enough for me. He also mentioned he didn't think you needed to flush the ECU loom, but that if you were to check and clean the plug at the ECU every week or 2 (which is a 10 min job) that eventually the oil would stop coming (assuming you have replaced the injector loom of course). Sounds reasonable, but I will see how I travel.
Also thanks to RR P38 for pointing me in the right direction with regards to part no's and places I didn't know about to purchase in Sydney, plus even going so far as to give me some in person tips later in the week. Cheers,
Pads
