Hi there so the story goes.....2008 GT Spec B auto wagon running stage 1 tune only otherwise stock.
Engine has 185K and I did the big end bearing at 120K'ish. Got a new bottom end installed and it's been running really well until about 2 months ago. I noticed lot's of white smoke on start and losing oil (about 0.5 Litre every 1000kms). White smoke was always on startup and was huge clouds so I figured coolant. Once the engine was warm I revved hard and no more smoke not white or blue . Wondered where the oil was going and coincidentally (or not) a breather hose broke a few weeks later and oil was pouring out. Smoke started pouring out of the engine scoop.
Interestingly didn't notice really any major drop in power at all despite a rough idle in low revs. Reading the forum I suspected ringland failure and pictures tell the story.
Now having a full rebuild with forged pistons, reconditioned head, STI injectors and STI turbo, dump pipe and high flow cats but back section of exhaust will remain stock. It will also have a custom tune. While it's being rebuilt is there anything else I should consider bearing in mind it's an auto and my target is to have good but safe power so it doesn't need to have another engine out episode.
