RS Aizawa ITB 1.6 - valve stem seals - improvements while in the head ?

[atlex]

So this is a very late follow-up but I thought it worth mentioning.. I moved to a thicker oil - 10w50 and that solved most of the smoking issue but I could still, let's say, 'provoke it' ;)

After having seen some higher oil temperatures (on the motorway) now I had some data collection in place for that (bosch combo sensors wired up to the link g4x) - a few days ago I switched to a higher flowing thermostat (Made in USA, 160f 72c) - and that dropped my coolant and oil temps both by around 20c - coming from max 126c to max 106c oil and from 100c coolant to 80c coolant.

Result - 40kpa more oil pressure minimum, sometimes more, and I can't get it to dump smoke on over-run at high revs - thinking being the higher temps were causing the rings to lose tension.

RS Delta is now asking me to do a video.. so, one day.. one day! I feel a bit more tempted now.
