Thankyou. Will look into the amount of support they have for hard cornering. 

Hi Gregory. Have you finished car mods? Can I ask if you have found a good experienced mech in Melbourne area that you would trust with ISF header install. I plan to get the full rr racing kit. Don’t know anyone who tunes in melb. I’m in Geelong. 
thanks Carlos.

I have tried a number of different oil blends and weight with some success but after driving for maybe 500kms the properties of the oil seem to change and the ticking timing chain noise returns.

Hi Grant. Did you ever get this resolved? I have a 2012 with same problem. I am a bit to try a much easier and cheaper fix. There are quite a few posts on forums suggesting ( as per a Lexus bulletin) that the problem could also be as simple as the idler belt tensioner pulley. Can I also ask if you found someone good with ISF in Melbourne? Im in Geelong and need headers done as well. 
Thankyou, Carlos.
